Description
This all-in-one car seat is designed for birth through booster. This model features LeverLock vehicle belt installation.
It transitions from a rear-facing harness (5-40 lbs, up to 43”) to a forward-facing harness (26.5-65 lbs, up to 54”) to a booster (40-100 lbs, 44”-57”). A removable newborn positioner supports infants weighing 5-11 lbs.
The slim, space-saving design fits into your vehicle without compromising comfort. Two CupFolders fold in when not in use to maximize space.
Designed with ClearTex flame retardant-free materials, OneFit Max ClearTex is GREENGUARD Gold Certified for low chemical emissions, contributing to healthier air quality around little passengers.
OneFit Max provides 20% more rear-facing legroom (compared to other OneFit car seats) and multiple recline options in every mode of use. The easy-adjust headrest system adjusts with the harness to grow with them.
For rear-facing installation, OneFit Max includes premium LATCH connectors and a SuperCinch force multiplying tightener. RideRight bubble levels work in tandem with the eight-position leveling system to provide improved vehicle fit and child comfort.
For forward-facing installation, OneFit Max features the LeverLock Self-Tensioning Lock System. This provides a secure vehicle seat belt install with minimal effort. Installation is as simple as open-route-close.
The flex-forward crotch buckle stays out of the way for easier loading, while harness pockets keep straps and buckles contained until ready for use. The quick-secure magnetic chest clip also offers easier ins and outs.
OneFit Max includes a steel-reinforced shell and sculpted EPP energy-managing foam.

Like all car seats, ridiculously hard to install correctly
Great car seat, but like all car seats, it is ridiculously hard to install correctly, and I would guess most are not. The latches are great, but those are not the “preferred” method according to the manual, and can’t be used for a 40+ lb. child. The tether strap can be frustratingly difficult to lengthen and tighten in-place and should be redesigned. Have each design engineer swap a car seat between two cars for a week and they will understand perfectly. The manual should be edited for clarity, leaving out the fancy trademarked names for different seat components.

Sturdy and durable, but the harness release button and strap isn’t easily accessible
I just bought this car seat and although it seems very sturdy and durable I wish the seat fabric fit snuggly around the Harness Release Button and the Harness Adjustment Strap, the strap slips below the fabric and it can be very difficult to pull it out. If I had noticed that in the pictures before I purchased I would’ve chosen the OneFit instead

Very comfortable and safe
We bought this car seat to replace an old seat that was falling apart. Our son has chronic kidney disease and needs a wide seat due to his medical equipment. After looking at many car seats, we found this one to be by far the most comfortable and the one that adapts to his needs without compromising safety or breaking the bank. We are happy with our purchase and so is our boy.

Tried and true ! Best car seat out there
I love this car seat! I have kids aging from 12-1 year. I have used this car seat over the last 12 years and I can just tell you this car seat is the best! The newest model I’m in love with as the ease of the car seat is amazing!

Fantastic car seat!
Incredibly easy to install and my 1 year old fits so well and looks so comfortable. We had the KeyFit 35 before getting this one, so I knew I loved Chicco.

Happy mama!
Great convertible seat! I had the original OneFit and loved it so much I was excited to try this new version. Love the upgraded harness pockets and buckle that help loading in the child easily. I was especially impressed with the thickness of the padding as my child loves a plushy comfy seat (we have zip air versions of their other Chicco seats) and the sleekness of the style.

Love it, just really big!
Love this car seat! Only downside is that it is really big! Almost didn’t fit in my husband’s ford explorer. The front passenger seat has to be pulled forward all the way. I’m glad we found this out before purchasing one for my car as well. Unfortunately, my car is smaller so I will have to buy something else. But overall, installation was easy, fabric is soft, and it looks so comfy!

THE BEST convertible car seat on the market!
Great convertible car seat! As someone who went from CYBEX to Chicco, the seat has premium quality material, easy installation, and A+ safety. Checked all our boxes at a fraction of the cost. We thought it would be challenging getting our 6 month old in and out- no hassle at all. Side note chubby baby approved.

Perfect Car Seat
Absolutely love this car seat for my grandson. It is so easy to install and the extra leg room is a super plus! The material is very comfortable and soft and love that he can grow into this car seat. Would highly recommend to anyone looking for a All In One Car seat for their little one!
