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.

OneFit Max CLearTex Al-in-One Car Seat
This a high quality car seat with plush washable inserts and great adjustability. Its ability to convert so we can have it for many years is clutch. The seat also received rave review from the hospital car seat technician which made us feel estremely comfortaable in our decision.

Safety issues with the top clip
Recieved this as a replacement to the older version I had after being in a car accident. The magnetic clip is terrible. I've had it one month and it keeps sticking when you push the top and bottom buttons together to clip it. The buttons take awhile to become unstuck causing 10 minute+ delays on going anywhere.
I would like a response from Chicco on a resolution for this as well. It's an expensive carseat to be having this many safety issues one month in.

Horrible install
Materials, cup holders, aesthetic 10/10. Install is literally 2/10. I have a chevy suburban and can barely get this in my vehicle correctly. The recline is off and the bubble never stays in place. The latch system isn’t easy to use and only goes to 40lbs the rear facing seat belt install is next to impossible and none feel as snug as my Nuna RAVA. I purchased a chicco booster and was SO impressed I bought this for our newborn since I do a convertible from day 1 and I hate to say but I wish I…

From NextFit Zip Max to OneFit Max - a toddler parent perspective - Embracing Change
Overall really enjoy the carseat (4.5/5 stars) and feel it provides great protection for my little one(s)! New to us model as our older child has the previous (closest-related option) model of the Chicco NextFit Zip Max which I would give a 5/5 stars.
My only two qualms I have encountered or prefer differently to what is available on this model is the lack of a zipper removal option for cleaning the cover (just makes it easier and wish it was an option on this model as it was on the…

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.
