Customers say
Customers find this car seat to be heavy-duty and solid once installed, with excellent build quality that will last for years. The seat is easy to install and adjust as children grow, providing good support for neck and head, and customers appreciate its safety features that keep children secure on the road. The cup holders remove for easy cleaning, and customers consider it worth the price. While customers find the car seat comfortable, they note it is pretty heavy.

Very happy with this car seat!!
My little one outgrew his infant car seat and I looked for months trying to find one to suit our needs. Most importantly I was looking for additional safety features!Pros: For my Honda odyssey it fits better than my other seats (graco and Evenflo).Installation- this always gives me anxiety because it usually takes me forever to install and I never get it snug enough. The Evenflo 360 is a nightmare to install for me. This was AMAZING. I was literally telling so many moms about the installation and how fast, easy and SECURE it was.Seat cushion for younger babies has very obvious instructions on weight so you donât have to look back in the manual.The level indicator is available to see on both sides which is a big win for 2 car seats.Comfort- baby was struggling to nap in his old seat and spent hours crying. I moved him into this one and though he still has taken some time to settle in heâs actually napped for me in the seat. I truly believe heâs more comfortable.Cons: itâs very heavy! (Honestly not really a con for me, but I know for some it can be).I havenât been able to adjust my daughterâs seat to a more comfortable recline position for her comfort without keeping it within the level indicator. I need to look into this further since sheâs complaining that she feels sheâs sitting too far forward.I have 2 of these seats rear facing for my 10 month old who is 20 pounds and daughter 4 years and 30 pounds. Looking forward to long rear facing and safety with these seats

Great Car Seat!!!
I looked heavily into purchasing a car seat before deciding what car seat is the best for my baby. My biggest concerns were:1. Safety2. Longevity (Weight/height capacities)3. PriceWith those 3 things in mind I ultimately decided on the Britax One4Life. It is rated one of the safest car seats in US and European standards. It has different modes that will grow with your child up to booster seat mode which supports up to 120 pounds. Lastly the price tag is a little hefty, but with the idea that I won’t have to buy a booster seat it made sense to go with this one. My daughter has been using it for about 8 months now, and we absolutely love it!

Favorite car seat for my (soon to be) three kids!
Weâve bought five of these because it is our favorite car seat. Iâve also recommended it to at least three friends. They are so easy to install and the kids are comfortable in them. I really like that the rear facing weight limit is so high because I plan to keep my kids rear facing as long as I can. My one complaint is that the cup holders pop off easily, but in the grand scheme that isnât that big of an issue. Will continue to buy these as we have more kids!

Highly recommend
I just purchased this car seat. First offHow it looks: beautiful love the style comes in many colors and styles i did the one 4 life click tight ( it is actually true it installs tightly). Supper soft and easy to follow instructions.What features: well I purchase this for easy installation and it also looked very comfortable too when it arrived it had many cushions and air netting on the sides for to breath. Side button with one push and easy to adjust tilit It was easy to find the buttons all labeled side and under the seat.Pros: easy to read and understand, easy to adjust and installation was a breeze. Once installed correctly it dosent move at all very impressive as I have had many car seats and they always move a little even once installed correctly this one was zero movement highly recommend for safty.Con well I don’t really have any yet it is so far everything I hoped for.So weight: well it is on the more heavier side but it’s not any heavier than Carring a baby carrier with base. It is solid to carry and solid once buckled.Other qualities it also is approved for other transport such as a plan if you wish to fly.What I love is the tilt feature and how it grows with your child, easy to install and read direction on the car seat visible and it is in two languages. The cushions for the head is very comfortable.Highly recommend for baby on up however I already pass the baby stage carrier and purchase this after my child was already one. It can even use for infants up to 10 years oldAgain highly recommend

Yup, Buy it!
Very happy with this carseat! This is the 3rd one we’ve bought. We purchased and returned two as they felt cheaply made, unsafe and we didn’t like the fit as well as how much they moved around after being tightly installed.This one is the exact opposite! It feels incredibly well made and safe, it doesn’t budge from its position tightened down in the car, our 8 month old fits great in it and I’m happy with the amount of padding around the head.Great quality, great fit, durable, manufacturer takes the safety of your child seriously! Highly recommend!

Quality Car seat that grows with your child
Great value for the money with easy installation. Quality sturdy materials with a very handy cup holder as the child is older. Comes with Newborn insert, and grows with your child, rear facing, forward facing and booster seat in one. I was really pleased with the functionality of this Car Seat

Very sturdy but hard to use click right difficult to click into place
I have two of this exact car seat. Both have issue with shoulder straps being even. Both car seat shoulder straps one is tighter than the other when in place on the child. Cup holders remove can be washed easily. The click tight feature to snap in place with the seatbelt are hard to snap in place if you have seat belt tight enough in my opinion. But overall very sturdy, take lbs a high amount of weight for child car seat. Has every seat option you would need as child grows. Easy push button to adjust the should height. Heavy car seat.

Esa facilÃsimo de instalar con la función clicktight, es un poco más costoso que otros muy populares, pero yo lo compré en descuento y vale totalmente la pena, además es muy acolchonado para comodidad de los babies, lo recomiendo ampliamente.
