The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride. *Britax cannot guarantee 3-across fitment in all vehicles.

Recommendation – Britax strongly recommends:

Children ride rear-facing to the highest weight or height specified

Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed

The top tether be used at ALL times when installing the child restraint forward-facing.

Excellent support and comfort.
Size: 12, Color: Black/Carrier Grey
A comfortable, lightweight shoe, with a nice heal cushion that gives slightly but not mushy or squishy. Very breathable. A solid choice for everyday sidewalks and trails.

Almost perfect shoe for any use.
Size: 9.5, Color: Steel Grey/Cloud Grey
Almost the perfect shoe for anything if you get the right size. I sent back 1st pair, no reviews on new model so found out hard way sizing is a bit off. Definitely size down a half size! They are long! Also note that if you're feet are at all wide, go for wide version. I have normal width(4 1/4 at widest point) feet and its snug on me. My only real complaint about these shoes is they could use about 10% more arch. My arch is medium height. They're so comfortable I didn't even notice until the end of a long work day. Could also just be due to my current (194) weight. Color/design is fantastic, though I would like to see more color options like previous models had. Hopefully they just haven't launched full line-up yet, since I purchased in first month of availability. Also, these are seriously better than my expensive Kayano lite 2's.

Cute but size up
Size: 5 Toddler, Color: Beige Silver Glitter, Size: 5 Toddler, Color: Beige Silver Glitter
These are super cute, made well, feel much more solid than any other jellies we’ve purchased but size up. These are the size 5 Melissa jellies against the size 5 Sophia Grainge Mary Jane’s. These Melissa wouldn’t go on her foot, the SG Mary Jane was huge.
