The Britax Poplar Convertible Car Seat can safely accommodate children up to 50 pounds while rear-facing and easily transitions to a forward-facing car seat as your child grows.

*Britax cannot guarantee 3-across installation fitment in all vehicles.

 

Specifications
  • Convertible design car seat works as a rear-facing car seat with the infant insert, and converts to a forward-facing car seat.
  • 2 additional premium inserts and padding that help create refined comfort and a tailored fit. 
  • ReboundReduce™ Stability Bar is a carbon steel bar that easily attaches to the car seat when installed rear-facing. It minimizes the movement in the event of a crash; it must be removed when installed forward-facing 
  • With ClickTight, you know it’s right in just 3 easy steps: open, buckle, and close.
  • Infant inserts are specifically designed to fit newborns 22 lbs. and under.
  • 5-point safety harness helps evenly distribute crash energy to keep your child safe.
  • Fully open seat belt paths are clearly labeled and easy to access, while the automatic tensioner takes care of the tightening.
  • Patented v-shape top tether has two connection points to help slow and reduce forward movement in a crash; easily stores away when not in use.
  • The fabric is naturally flame retardant with no added FR chemicals
  • Safecell Technology acts as a crumple zone, helping to keep crash energy away from your child.
  • The 14-position harness and headrest move with one hand to grow with your child.
  • Washer and Dryer Friendly, no more hand washing or waiting for the cover to air-dry; just quick and easy cleanup, so you can keep moving.
  • The 2 cup holders slide in and out and are dishwasher-safe for easy cleaning between rides.
  • Easy-read level indicators with 6-position and quick-adjust recline help you find the most comfortable fit for your child and the best fit for your vehicle.
  • 1-Year Limited Warranty.

Not durable, cheaply made for big guys 6’4 235lbs
Color: Gray Navy, Size: 13-16, Color: Gray Navy, Size: 13-16
Don’t recommend for men. Boys maybe but not men. I wore them twice for about 3 hrs before bed. Went to put in the 3rd time and they ripped. It’s literally a small sheet of Sherpa from the shoe and plastic wrap. I also got the bigger size and they still don’t fit right. I bought these right before my trip upstate during the holidays, because I live in Florida. I paid $20+ for these, hoping they would be good. 1/10 recommend

Size 13 (not 13-16)
Color: Gray Navy, Size: 13-16
I have a size 13 foot and these Winter Socks/Slippers just barely cover the length of my foot, so if you are over size 13 these will be too small_ they are well made and insulated_ they look nice, just like the pic, and I can go from my house to the my car in the snow without the bottoms getting wet_ they are cozy without my feet getting hot_ just wish they were a half inch longer on the foot size to be a more perfect size 13_ they feel about 12-1/2

Awesome but loses shape
Color: Long Black, Size: 10-13
This is comfy and keeps my feet warm but definitely doesn't hold shape good to wear indoors but don't think about walking long distances.
