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.

This is a great brand! The products are quality, and well made! These pillowcases are extremely soft and comfortable! The fabric is luxurious! The colors that I ordered are true to description! And these pillowcases are generous with size - it isn’t difficult to put your pillow in th case!! The cases are not slick/slippery! They are soft and comfortable (I know I already said that, but it’s worth repeating!! They look great on the bead like a sham as well!! Best of all, they are more than worth the money! Highly recommended!!

So soft and cool on my face at night. Fit my pillows perfectly and don’t slip off. They’re thin but thick at the same time (if that makes sense), super breathable and clean well in the washing machine. I cosleep so stains happen and I love good quality fabric that doesn’t stain easily.
