10 Best Convertible Car Seat For Kia Soul

If you drive a Kia Soul, you know the back seat is cozy — which makes choosing the right convertible car seat more important than ever. You want a seat that keeps your child safe, fits the car without crowding other passengers, and grows with your child so you don’t need to replace it every year. Picking a slim, easy-to-install model with strong safety features and washable covers will save you time, money, and stress on every trip.

Top Picks

How We Picked

You need a seat that fits the Kia Soul’s compact rear without compromising safety or comfort. We prioritized: 1) Fit for small cars (slim width and low profile), 2) Safety features (5-point harness, side-impact protection, strong frames), 3) Ease of installation (LATCH or clear seat-belt routing, level indicators), 4) Rear-facing limits (longer rear-facing capability improves safety), 5) Adjustability (no-rethread harness, multi-position headrest and recline), 6) Cleanability (machine-washable covers), 7) Longevity (3-in-1 or 4-in-1 designs that cover many weight/height stages), and 8) Real-user feedback on comfort and durability.

Scores weigh safety and fit more heavily since those matter most in a small vehicle.

Disney Grow and Go Convertible

This Disney Grow and Go is a true grab-and-go solution if you want one seat that carries your child from newborn rear-facing through forward-facing toddler and then to a belt-positioning booster. You can expect soft, machine-washable padding, a QuickFit one-step harness and headrest adjuster, and removable inserts that keep smaller babies snug.

It installs with LATCH for faster setup, reclines into three positions for naps on the road, and has removable cupholders that make cleaning easy. For daily runs, school drop-offs and longer drives, it handles the transitions smoothly; for special outings you’ll appreciate the comfy padding and easy buckling. If you want a playful print (Midnight Minnie) with practical features, this is one to seriously consider for a compact car like a Kia Soul.

What People Say

Reviewers repeatedly call out the comfy padding, easy-to-use harness adjustments, clear installation instructions and the convenience of removable cupholders and machine-washable covers. A few noted latch tightening can take a little patience but overall feedback is very positive.

Overall Sentiment: Positive

Everyday Use

At about 19.25 x 24.5 x 24.5 inches and 18.36 pounds, it’s sturdy but still manageable to move between cars. The removable, machine-washable pad and detachable cupholders are genuinely handy for day-to-day life—cleaning is quick and you won’t need to wrestle the harness to remove the cover. The three recline positions help keep naps comfortable on longer drives, and the one-step harness/headrest adjustment saves time during stage changes.

Safety 1st Grow and Go

You get a true all-in-one that covers rear-facing baby through forward-facing toddler and up to a belt-positioning booster. The Grow and Go offers QuickFit one-motion headrest and harness adjustment, removable grow-with-baby pillows, a machine-washable seat pad and removable cupholders so cleanup is simple.

It installs with LATCH or the vehicle seat belt, has a reclining setting for naps and visible belt paths for easy belt routing when your child is ready. For daily drives, school runs and longer road trips it handles transitions well; for special rides with grandparents or weekend outings you’ll appreciate the padding and the side-impact protection. In a compact car like a Kia Soul it will usually fit, but it can feel a bit snug if you’re tight on rear-seat space, so test-fit before relying on it as your only seat.

What People Say

You’ll see a lot of comments about how comfortable and well-padded the seat is, plus how the harness and headrest adjust quickly as kids grow. Parents also praise the straightforward installation and the easy-to-remove cover and cupholders for cleaning. A common caveat is that the seat can feel bulky in smaller cars, so double-check fit in your Soul before committing.

Overall Sentiment: Positive

Safety Highlights

Meets or exceeds federal safety standards, 5-point harness, engineered side-impact protection, LATCH and seatbelt installation options, QuickFit headrest and harness adjustment, visible belt path for booster use and grow-with-baby inserts for a proper fit at smaller sizes.

Everyday Use

At roughly 24 x 19.25 x 24 inches and about 13.2 pounds, it’s substantial but still manageable to move between cars. The seat pad snaps off for machine washing, cupholders detach for the dishwasher, and harness holders keep straps out of the way when you load your child.

The 3-position recline helps with naps, though the overall bulk means it can be snug in tighter rear seats like a Kia Soul—try a test install to confirm clearance with other passengers.

Why You’ll Like It

• 3-in-1 use: rear-facing infant, forward-facing toddler, belt-positioning booster
• QuickFit one-motion headrest and harness adjustment for easy stage changes
• Machine-washable seat pad and removable, dishwasher-safe cupholders for easy cleaning
• LATCH and seatbelt installation with visible belt paths for straightforward installs
• Removable grow-with-baby pillows and side-impact protection for a snug, secure fit

Graco SlimFit 3-in-1

You’ll notice right away this is built to grow with your kid — rear‑facing to forward‑facing to a highback booster — while being friendlier to tight back seats. The SlimFit trims about 10% of bulk by tucking the cup holders away and keeps things neat with a harness storage compartment for booster mode.

It uses Graco ProtectPlus engineering for multiple crash‑direction protection, a no‑rethread Simply Safe Adjust harness and a 10‑position headrest so you can fine‑tune the fit as your child gets taller. Daily errands, school carpools and longer road trips all work well here: it’s comfortable for naps with a 4‑position recline and installs quickly with the InRight LATCH click.

For special rides — hops to grandparents’ house or weekend outings — you’ll like that it’s easy to move between cars. In a compact hatch like the Kia Soul it usually saves space compared with bulkier models, but I’d still recommend a quick test fit to be sure it clears your front seat.

What People Say

You’ll see a lot of parents noting how well it fits smaller cars and how straightforward installation is with LATCH. Reviewers praise the headrest adjustability and the compact footprint — many call it a practical choice if you need a long‑lasting seat that won’t eat up backseat space.

A few mention that fit and recline can feel different depending on your vehicle, so a quick in‑car test is helpful.

Overall Sentiment: Positive

Safety Highlights

Graco ProtectPlus Engineered (frontal, side, rear and rollover crash protection), 5‑point harness, side‑impact protection, InRight LATCH with audible click, visible belt path for booster mode and harness storage to keep straps tucked when used as a belt‑positioning booster.

Everyday Use

The SlimFit trims backseat bulk and is designed to be moved between cars when needed. Rotating cup holders and harness storage help keep things tidy; the seat cover wipes clean and most pads remove for deeper cleaning.

You get a 4‑position recline for naps and a no‑rethread harness for quick adjustments. Dimensions are roughly 21.5 x 19.9 x 25.5 inches and it weighs about 24.6 pounds, so it’s manageable to transfer but not featherlight — test fitting in a Kia Soul or similarly compact vehicle is a good idea before you finalize placement.

Why You’ll Like It

• 3‑in‑1 lifespan: rear‑facing harness to forward‑facing harness to highback booster
• Slim, space‑saving profile with rotating cup holders that tuck away
• Graco ProtectPlus Engineered for multi‑direction crash protection
• Simply Safe Adjust no‑rethread harness and 10‑position headrest for easy resizing
• InRight LATCH with audible click and harness storage for booster mode

Graco Grows4Me 4-in-1

You’ll appreciate how this seat is built to last — it moves from rear‑facing harness to forward‑facing harness, then to a highback and backless booster so you won’t be swapping seats every year. The no‑rethread Simply Safe Adjust harness and 10‑position headrest make it easy to dial in a secure, comfortable fit as your kid grows, and the 6‑position recline helps for short naps or longer drives.

LATCH installation speeds things up and the steel‑reinforced frame plus Graco ProtectPlus engineering cover multiple crash directions. For everyday errands and school runs it’s comfortable and adaptable; for special outings or longer road trips you’ll like the plush inserts and sturdy feel.

In a compact car like the Kia Soul it can take up a bit more room than slim models, so do a quick test fit, but its long lifespan and adjustability make it a practical pick if you want one seat that grows with your child.

What People Say

Parents often call out how solid and adjustable the seat is — reviewers report it feels secure once installed, is comfortable for kids, and grows with them. A few mention the bulk compared with slim models and suggest testing a fit in smaller cars like the Kia Soul before committing.

Overall Sentiment: Positive

Safety Highlights

Graco ProtectPlus Engineered protection for multiple crash directions, side‑impact tested occupant retention, a 5‑point harness, steel‑reinforced frame and LATCH installation. The Simply Safe Adjust system keeps harness and headrest aligned so you get a consistent, snug fit as your child grows.

Everyday Use

This seat is designed for long use — the 4‑in‑1 stages cover roughly 5–110 lb and the 10‑position headrest plus 6 reclines help you find a comfy fit. It’s reasonably easy to move between cars, though some reviewers say initial installs can take time until you get the tightening technique down.

Covers wipe clean and many pads remove for deeper washing. Product dimensions are 20 x 21.5 x 24 inches and it weighs about 22.5 pounds, so it’s manageable to transfer but not ultra‑light.

Why You’ll Like It

• 4‑in‑1 use: rear‑facing harness to backless booster for long lifespan
• Simply Safe Adjust no‑rethread harness and 10‑position headrest for quick resizing
• 6‑position recline for comfort on short and long drives

Graco TriRide 3-in-1

You’ll like how this seat covers three stages so you don’t have to swap seats every few months. The headrest and harness move together with the No-Rethread Simply Safe Adjust system (10 headrest positions) and there are 6 recline settings to help with naps on short errands or longer road trips.

Installation is eased by LATCH and an easy-to-read level indicator, and the steel-reinforced frame plus Graco ProtectPlus Engineered testing give you added peace of mind. For everyday school runs and grocery trips it’s comfy and practical; for weekend drives or holiday visits the plush inserts and machine-washable pad make life easier. In a compact car like the Kia Soul it’s a snug fit — it will work, but I’d recommend a quick test fit to be sure you still have enough rear passenger space.

What People Say

You’ll see parents praise the seat’s sturdiness, comfortable padding, and how it grows with their child. Many note straightforward installation once you get the tightening technique down and appreciate the recline and removable inserts. A few mention the seat takes a bit of room in smaller cars and that cup holders can be pulled off by curious toddlers.

Overall Sentiment: Positive

Safety Highlights

Graco ProtectPlus Engineered covers frontal, side, rear and rollover crash scenarios, plus a 5‑point harness, steel‑reinforced frame, LATCH installation and open‑loop belt guides for proper belt positioning in booster mode. The No‑Rethread Simply Safe Adjust system keeps harness and headrest aligned for a consistent fit.

Everyday Use

This seat is built for long use and everyday life. The seat weighs about 18.45 pounds and measures roughly 20 x 19 x 23.25 inches, so it’s manageable to move but not tiny.

You get two easy‑to‑clean cup holders, an integrated harness storage compartment for booster mode, and a machine‑washable pad. For a Kia Soul you’ll likely have enough space, but expect a snug rear seating area and do a quick test fit before deciding.

• 3‑in‑1 use: rear‑facing harness to forward‑facing harness to highback booster for long lifespan
• No‑Rethread Simply Safe Adjust harness and 10 headrest positions for fast, consistent resizing

• LATCH equipped and easy‑to‑read level indicator for simpler installs

Graco Tranzitions 3-in-1

You’ll like how this seat really grows with your kid so you don’t have to juggle multiple car seats. It converts from a forward‑facing harness to a highback and then a backless booster, and the No‑Rethread Simply Safe Adjust system moves the headrest and harness together across nine positions so resizing is quick.

It’s fairly lightweight and portable at about 15.1 pounds, so tossing it between cars for everyday errands or a weekend road trip is easy. The twin cup holders and machine‑washable pad make snack time and spills less stressful.

In a compact car like the Kia Soul it’s doable, but expect a snug fit — do a test install to be sure you still have enough rear passenger space.

What People Say

You’ll hear parents praise the seat’s comfort, easy adjustments, and how it grows with their children. Many mention straightforward installs once you use the LATCH hooks or vehicle belt correctly, plus the convenience of cup holders and a washable pad. A common note: it can be a bit snug in smaller cars, so try a test fit in your Kia Soul before committing.

Overall Sentiment: Positive

Safety Highlights

5‑point harness in harness mode, No‑Rethread Simply Safe Adjust system that keeps headrest and harness aligned, LATCH (ISOFIX) hooks for secure installation, and weight/height guidance across stages (forward‑facing 26.5–100 lb; booster 40–100 lb) to match industry standards.

Everyday Use

This seat is built for everyday life and travel. At roughly 17.4 x 19 x 26.5 inches and 15.1 pounds it’s easier to move than some bulkier models, which helps when you’re switching between family cars or a rental. The removable, machine‑washable pad and two cup holders make snacks and spills easier to manage. For a Kia Soul expect a snug rear seat fit; you’ll likely be able to install it, but do a quick trial to check passenger space and middle‑seat clearance.

Why You’ll Like It

• 3‑in‑1 design: forward‑facing harness to highback to backless booster for long use
• No‑Rethread Simply Safe Adjust harness and 9 headrest positions for fast resizing
• Lightweight and portable (about 15.1 pounds) for swapping between cars
• Two rotating cup holders and machine‑washable seat pad for easy cleanup
• Adjustable 5‑point harness for toddler harnessed use and secure booster transition
• LATCH-equipped for quick, stable installs in many vehicles

Safety 1st Everslim DLX

You’ll notice right away this seat is built to grow with your kid so you don’t have to swap seats every few months. It converts from rear‑facing for newborns (5–40 lb) to forward‑facing (22–65 lb) and then to belt‑positioning or backless booster (40–100 lb).

The slim profile is handy in smaller cars — it’s designed to fit up to three across — and the 10‑position headrest plus 5‑position base make getting a good fit straightforward. The visual SecureTech chest clip takes the guesswork out of buckling and the removable cover is machine‑washable for real‑life spills.

For everyday errands or longer trips you get a comfortable, durable seat that’s easy to clean and adjust; in a Kia Soul you’ll probably appreciate the slimness, but do a quick test install to make sure your rear passenger space works for your family.

What People Say

You’ll hear parents praise the seat’s comfort, soft cushioning and easy installs. Folks like the slim fit for smaller cars and the visual chest‑clip indicator.

A few mention the weight when moving it between cars, so plan for that if you swap seats often.

Overall Sentiment: Positive

Safety Highlights

5‑point harness in harness mode, SecureTech chest clip with visual buckle indicator, LATCH installation, multiple recline positions for correct rear‑facing angle and headrest/harness adjustments to match height and weight limits across stages.

Everyday Use

The Everslim DLX is practical for daily use and travel: the cover comes off for machine washing, cup holders detach for cleaning, and the adjustable headrest/base help keep your child comfortable on short errands or long drives. At about 25.6 x 18.1 x 23.6 inches and 29.8 pounds it’s slimmer than many all‑in‑one seats but not the lightest — good for long‑term use in a primary car, less ideal if you’re constantly carrying it between vehicles.

In a Kia Soul the slim design usually helps, but do a test install to confirm passenger space and middle‑seat clearance.

Why You’ll Like It

• 4‑in‑1 design covers newborn to booster so it lasts for years
• Slim profile that can fit up to three across in many back seats
• SecureTech chest clip with visual red‑to‑green indicator for easy checking
• 10‑position headrest and 5‑position base for fine tuning fit as your child grows
• Removable, machine‑washable seat cover and infant inserts for easy cleanup
• LATCH installation for a stable, straightforward install

Britax One4Life Convertible Car Seat

You’ll appreciate that this is a true all‑in‑one: rear‑facing for infants, forward‑facing harness for toddlers and preschoolers, then a high‑back booster as your kid grows up to about 63 inches. Installation is one of the things parents keep talking about — ClickTight takes the guesswork out of threading and tightening the belt — and the steel frame plus SafeCell crumple zone give a reassuringly solid feel.

The Cool N Dry knit fabric breathes and wicks moisture, so long rides don’t get sticky. For daily errands it’s comfy, easy to adjust (15‑position headrest and a no‑rethread harness) and the cover is machine‑washable when life happens; for travel it’s approved for other transport and has features that keep kids comfortable on longer drives.

If you drive a Kia Soul, do a quick test install first: the seat is well built and safe, but it’s on the heavier and wider side so fitting three across or moving it between cars can be a challenge. Overall, if you want one seat that truly grows with your child and makes installs simple, this is worth a close look.

What People Say

Parents commonly praise the ClickTight install and the solid, reassuring build. Many mention how comfy the padding is and that adjustments are simple as kids grow.

A few note the seat is heavy and fairly wide, so think about how often you’ll move it or whether you need to fit three seats across.

Overall Sentiment: Positive

Safety Highlights

5‑point harness for harness modes, high‑strength steel frame, SafeCell crumple zone, patented V‑shaped tether and two layers of energy management. ClickTight helps ensure a tight seat belt install and the no‑rethread harness keeps harness height aligned with headrest changes.

Everyday Use

This seat works well for everyday driving and longer trips: the cover comes off for machine washing, cup holders pop off for cleaning, and the headrest/strap system makes sizing quick. Keep in mind it weighs about 30 lb and is on the wider side, so it’s ideal as a long‑term seat in a primary car rather than something you constantly move between vehicles.

In a Kia Soul you’ll likely find it comfortable and safe, but test a real install to confirm back‑seat clearance and whether it fits alongside other passengers.

Why You’ll Like It

• One seat that covers roughly 5–120 lb and up to 63 in — use from infant rear‑facing to high‑back booster
• ClickTight installation for a clear, confidence‑building install process
• High‑strength steel frame plus SafeCell crumple zone and patented V‑shaped tether for energy management
• Cool N Dry knit fabric for better airflow and moisture wicking on longer rides
• 15‑position headrest with no‑rethread harness so you can adjust height and straps quickly
• Machine‑washable cover and removable cup holders for easy cleanups

Safety 1st Crosstown Slim All‑in‑One Convertible Car Seat

If you need one seat that really grows with your kid and won’t eat up back‑seat space, this is worth a look. The Crosstown Slim covers rear‑facing, forward‑facing harness and belt‑positioning booster stages, and its 17″ slim profile is handy when you’re trying to fit people (or other car seats) in the back of a Kia Soul. You’ll like the one‑hand harness/headrest adjustments as your child gets taller, and the removable, machine‑washable pad and dishwasher‑safe cup holders make daily life easier. For errands and short drives it’s comfortable and quick to clean; for longer trips the padding and multiple recline positions keep kids settled.

Do a quick test install in your Soul before committing — it’s narrower than many all‑in‑ones, but still worth confirming for three-across fits.

What People Say

You’ll often hear parents call out the slim fit, comfy padding and easy‑to‑clean cover. Many say installation felt secure once adjusted, though a few note it can take a bit of patience to get the install perfect in some vehicles.

Overall Sentiment: Positive

Safety Highlights

5‑point harness in harness modes, meets or exceeds federal safety standards, clearly marked belt paths for proper installation, 8 recline/height positions and an adjustable base foot for correct rear‑to‑forward transitions.

Everyday Use

This seat is built for day‑to‑day life: the pad comes off for machine washing, cup holders pop out for cleaning or extra space, and the slim frame is useful if you need to fit another passenger or seat beside it. The one‑hand adjustments make quick sizing simple, and the seat’s lighter, narrower footprint compared with some all‑in‑ones makes it a practical choice for a smaller car like the Kia Soul.

Still, test a real install to be sure of clearance and angle in your vehicle.

Why You’ll Like It

• Covers rear‑facing, forward‑facing harness and booster stages so you can use it for years
• Slim 17″ profile helps fit 3 across the back seat of many cars, useful in a Kia Soul
• One‑hand adjustable harness and 8‑position headrest — no rethreading as your child grows
• Easy transitions with clear belt paths and an adjustable base foot for rear‑to‑forward changes
• Removable, machine‑washable seat pad and dishwasher‑safe cup holders for quick cleanups

Graco Turn2Me 3-in-1 Rotating Convertible Car Seat

This is the kind of seat that makes everyday life with a little one noticeably easier. The Turn2Me rotates one‑handed from rear to forward facing so you can load and buckle without twisting your back — especially handy if you’re working in the tighter rear of a Kia Soul. It covers newborn through booster stages (4–100 lb across its modes), and Graco packs in practical touches: quick SnugLock installation with belt or LATCH, the InRight push‑button LATCH, a no‑rethread harness that moves with the headrest, and a 10‑position adjustable headrest.

For daily errands you’ll appreciate the rotation, harness storage pockets and plush inserts that keep infants cozy; for longer drives the multiple positions and ProtectPlus engineered crash protection give extra confidence. If you want one seat that grows with your child and reduces the contortions of buckling in a compact car, this is a smart pick — just try a test install in your Soul to confirm fit and clearance.

What People Say

Parents tend to praise the rotation for making buckling less awkward, and many call out how fast and secure installation is with SnugLock and the InRight LATCH. A few mention the seat is bulkier than slim models, so checking fit in a smaller car like the Kia Soul is recommended.

Overall Sentiment: Positive

Safety Highlights

ProtectPlus engineered protection for frontal, side, rear and rollover crashes, 5‑point harness in harness modes, No‑Rethread Simply Safe Adjust system for correct harness/headrest alignment, clearly marked belt paths, SnugLock installation system and InRight push‑button LATCH for audible, secure attachment.

Everyday Use

The rotating bucket saves you from awkward contortions when loading kids in a compact back seat, and harness storage pockets keep straps out of the way in booster mode. Plush head and body inserts cradle smaller infants and can be removed as your child grows. Quick installation and one‑motion harness/headrest adjustments make daily swaps and carpooling less of a hassle. Still, give it a quick test install in your Soul to confirm clearance and how the recline sits.

Why You’ll Like It

• One‑handed rotation for easier loading in tight back seats
• 3‑in‑1 design grows with your child from 4–100 lb
• SnugLock and InRight LATCH for quick, confident installation
• No‑rethread Simply Safe Adjust harness moves with the headrest

FAQ

Which Convertible Car Seats Fit A Kia Soul Best?

You’ll get the best fit in a Kia Soul with a slim-profile convertible seat or one known for space-saving design; models like the Graco SlimFit, Safety 1st Crosstown Slim, and Safety 1st Everslim DLX are built to be narrower in the back seat and often let you keep a passenger or second car seat beside them. That said, many full-featured all‑in‑one seats such as the Safety 1st Grow and Go, Graco Grows4Me, or Britax One4Life will also fit — they can be wider and heavier, so you should measure your Soul’s rear bench from door to door and compare it to the seat’s width, check whether cup holders or armrests will block the adjacent seat, and if possible do a test fit in-store or at home before you commit.

A quick rule of thumb is to measure before you buy and verify installation options in your owner’s manual so you know whether the seat will sit flush and allow proper recline and tethering.

How Do I Install A Convertible Car Seat Properly In A Kia Soul?

You should install the car seat following both the car seat manual and your Kia Soul owner’s manual: locate the LATCH anchors and check the vehicle’s LATCH weight limit, decide whether LATCH or the vehicle seat belt gives a tighter installation for your child’s weight, and use the car seat’s built‑in angle indicators or a rolled towel as recommended for correct rear‑facing recline. After installation push and pull the seat at the belt path — it should move less than 1″ (about 2.5 cm) side‑to‑side or front‑to‑back. Keep your child rear‑facing as long as they fit the rear‑facing height and weight limits, route the tether for forward‑facing seats, adjust the harness so you cannot pinch any slack at the shoulder, and keep the chest clip at armpit level. If you’re unsure, you can have a Certified Child Passenger Safety Technician check the installation — a brief inspection can catch common mistakes and give you confidence that the seat is securely installed.

What Should I Consider When Choosing A Convertible Car Seat For Long‑Term Use In A Kia Soul?

Think beyond just compatibility: prioritize a seat with weight and height ranges that match how long you want to use it rear‑facing and forward‑facing, look for a no‑rethread harness or easy harness and headrest adjustments so you can quickly get the correct fit as your child grows, and choose multiple recline/headrest positions to help with comfort and proper belt geometry in the Kia Soul’s relatively upright seats. Materials that are machine‑washable, removable cup holders, good side‑impact protection, and a solid installation system (clear LATCH or seat‑belt routing and level indicators) will make day‑to‑day life easier.

Don’t forget to register the seat for recalls, check the expiration date, and confirm that the seat’s base and dimensions will leave enough room for an adult in front or a third passenger if you need it — the most practical picks balance safety, adjustability, and a slim footprint for small cars like the Soul.

Customers Top Picks

When choosing between the Disney Grow and Go Convertible, Safety 1st Grow and Go, and Graco SlimFit 3-in-1, you mainly prioritize safety features and how well the seat fits in the Kia Soul’s narrower back seat. You also care about ease of installation, a slim profile and long-term adjustability, plus comfort and washable covers—Disney often wins for character and padding, Safety 1st for straightforward value, and Graco for compact versatility and multiple modes.

Wrapping Up

You want a convertible car seat that keeps your child safe and actually fits in the Kia Soul. If you need one seat that lasts years and offers excellent safety, the Graco Grows4Me is the top pick.

If conserving rear-seat space is your priority, choose a slim model like the Graco SlimFit or Safety 1st Crosstown Slim. Before you buy, measure your rear bench width and check that the LATCH anchors and recline positions work in your Soul.

If you need help installing, look for a certified Child Passenger Safety Technician in your area or use the manufacturer’s installation videos. Choosing the right fit now will give you safer, calmer rides and fewer seat swaps as your child grows.
