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.

Interesting pillowcase that does run cool to the touch
To begin: I'm a 64 y/o woman who still gets hot flashes, despite air-conditioning and a fan blowing on me at night. It's the sheets off then blankets on routine that so many of us know. I ordered this pillowcase hoping that I would find some kind of relief in the night, even it was only for my head. The fabric is very unusual. It's a silky nylon blend, very swishy and soft. It reminds me of luxury, expensive women's lingerie. It's extremely slippery, moreso when you have your head on it; there certainly won't be any resistance or pulling on the hair all night. I washed it before using it, put it in a mesh bag to protect it from getting snagged. It washed and dried as good as new. One thing to note: because it is so slippery the pillow may want to slide a little out of the pillowcase. I slept quite well and did not experience any heat or sweating on it. The reason for the 4* and not 5* is the price, at almost $20 it is a bit pricey for a rectangle of nylon fabric. I could see if it were real silk, but it's not. Otherwise it's exactly what it purports to be.
