The Willow S Infant Car Seat by Britax offers you peace of mind while riding with your precious cargo. This baby car seat is side impact tested and includes an array of features for your convenience. The ClickTight technology allows you to install the car seat securely and with confidence. The 5-point harness spotlights the RightSize system that allows adjustment points at the hips, shoulders, and between the legs, creating a perfect and cozy space for your little one.

The Willow S Infant Car Seat by Britax includes the Alpine travel car seat base equipped with a ReboundReduce Stability Bar that minimizes movement and maximizes safety and convenience. When it's time to stroll, the baby seat easily snaps to the Britax Brook, Brook+ and Grove strollers (sold separately) in both parent-facing and forward-facing modes, allowing baby to face the parents or face the world. This seat features a washer and dryer-friendly SafeWash car seat cover and inserts with naturally flame-retardant fabrics. Every part of this car seat is 100% FR free, so you can rest assured baby's precious skin is not in contact with any nasty chemicals.

  • NATURALLY FLAME-RETARDANT FABRICS: Featuring 100% fire retardant-free, naturally fire resistant fabrics as well as foam free of any added fire retardants
  • INFANT INSERT PILLOW: This rear-facing car seat is designed to provide a more comfortable and customized fit for newborns under 11 lbs

Free of added fire retardants

Britax is fully transparent about their manufacturing process and guarantee that their car seats are completely free of any added fire retardants. However, their products are manufactured in the same facilities as other gear that does contain FRs so there is a chance of potential FR carryover. We believe in full disclosure and transparency and appreciate Britax's honesty and effort to produce fire resistant products without the addition of chemical fire retardants.

Nice Coat, But Could Better
Size: Medium, Color: Black
I like this coat overall. It fits really well, nicely tapered, and a good weight, but the fabric has a sheen to it, very noticeable in brighter light, which I'm not crazy about. It doesn't have any inner breast pockets, and I don't feel secure putting my phone in the side pockets. I did get lots of positive comments from friends.

Great style chose for any occasion
Size: Medium, Color: Black
Genuinely the perfect fit and great for the style I prefer. Great material and thick to keep you warm but not to hot. Black is deep and adds that depth that I am looking for

The description states 100% cotton, but it is actually 100% polyester. I don't know what I was counting on... Returning
