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.

Good products but not packaged as a set
I was looking for a gift for my coworker. I thought this was going to come as a set in a box. Not 4 separate items, especially considering the fact that there is a review video posted here that shows a set in a big box together. On closer inspection that review is from a completely different set of Ordinary products not the ones featured in this collection. Why is a review featured for different items? Make it make sense.

Best product I have found!!! Love love love it!!
Color: Picotonic Shot
This product And all the other dr Melaxin products are awesome. I have seen visible changes in my skin and my forehead wrinkles or creases if you will have diminished. I have to creases in my forehead and one between my eyes and ai can’t even see that anymore and he one on my forehead has lightened up and is not as prominent. My skin is visible plumper I am 49 and look like I am maybe 38. I have probably spent thousands of dollars on all kinds of beauty products and none work like these!! Definetly purchase hem I just bought my second bottle. I have only been using this for three months and it deminished the wrinkles in that amount of time. Also get yourself the spicual shot as well it is the pink one it's a micro needling serum and you don’t feel tingly and you don’t get red irritated akin like you do with other micro needling products. Definitely buy all their products. If you do I would get their set of skin care with the serums the cleanser, the turmeric exfoliator,therice exfoliator that is awesome all you do it put a few drops where you have black heads and you rub it into your skin in circles and it pulls out the black heads and exfoliates at the same time. I will never buy another product again their entire beauty line is great they have all you would need for beautiful skin.
