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.

Puppy loves her baby
Purchased for a 9 week old puppy, she is now 18 weeks, took the heartbeat out and it’s her baby, drags it everywhere and hasn’t ripped it to shreds.

Incredible smoothly
I recently purchased the Heartbeat Puppy Calming Kit, and it has been a game-changer for my anxious puppy! The heartbeat toy is incredibly soothing and helps my puppy sleep soundly through the night. The lick mats and treat ball keep her entertained and busy, which has significantly reduced her separation anxiety. The quality of all the items is excellent, and they are durable enough to withstand daily use. This kit is a must-have for any new puppy owner looking to provide comfort and training aids. Highly recommend!

Durable and Great for Teething!
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
This Nylabone Power Chew Textured Ring is a great find! It’s a pretty big ring, which is perfect because my puppy can grow into it. She already loves it and spends a good amount of time chewing on it. She’s a big teether, so I was specifically looking for something she could gnaw on that wasn’t plastic, and this has been so much better than the other things she tries to get her teeth into. It seems durable, keeps her occupied, and the price is great for the quality. I’ll definitely be buying another one when needed!

As durable as expected.
Size: Large, Color: Femur Bone, Size: Large, Color: Femur Bone
My dog loves it—more than any other bone she’s ever had. It’s not quite as durable as regular nylabone, but we expected that. This photo was taken after around 2 hours of super aggressive chewing by a very big German shepherd. It has no discernible smell, but obviously it has a flavor because she doesn’t want to put it down even for trips outside. It’s soft enough that it doesn’t cause that “are their teeth breaking?!” sound that a lot of offbrand nylon chews have. The classic femur shape is perfect. It’s the easiest shape for her to hold naturally. All around, perfect dog chew.
