Ready to go with room to grow! The Poplar® convertible car seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® installation and slim SpaceSaver™ design. This convertible car seat accommodates up to 50 lbs when installed rear-facing, allowing your child to ride rear-facing longer.

ClickTight technology provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening. This baby car seat lets you easily adjust the 14-position no-rethread harness and headrest to help create the perfect fit. Slim outside and spacious inside, this convertible car seat features 17-inch SpaceSaver technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort. The rear-facing car seat includes a patented SafeCell® crumple zone and a V-shaped top tether to help manage crash energy. Carbon steel frame and belt paths provide strength and stability. The car seat cover fabrics are naturally flame-retardant with no added FR chemicals, and they’re safe to machine wash and dry time and again. *Britax cannot guarantee 3-across installation fitment in all vehicles

Good pillow, useless case
Color: Grey, Size: S-16 X 12 Inch
Nice pillow, small and portable. No horrible smell. Negative 1 star for the carrying case which is twice the size of the pillow. If you think you will use it to compress your pillow for travel, think again. It just expands back in the bag. Totally useless unless you’d like to store rocks in the bag instead.

Great for car naps and family road trips.
Color: Grey, Size: S-16 X 12 Inch, Color: Grey, Size: S-16 X 12 Inch
Adjusts to any position, no weird smell, packs well and hangs from headrest. Soft, supportive, and easy to clean after kid messes. Slightly bulkier than some, but the comfort is worth it!

A Travel Pillow That Actually Works!
Color: Sky Blue, Size: M-17.7 X 13.8 Inch
I fly fairly often and have gone through a few different pillows that I thought would be great but left me disappointed! I’m honestly so happy with this pillow. It fits easily in my backpack, and it doesn’t look ridiculous if I hanging it on my backpack if I’m packing a lot. It’s thick enough to support my head against the window/wall without feeling too bulky. I usually sleep really poorly on planes, and I’m not going to say that this was the magic charm, but I definitely slept more comfortably. It’s also great support against your lower back if you’re not sleeping. Some have mentioned a smell, but honestly it just smells like memory foam usually does and it’s not overpowering. I’ve only used for a few flights so far but I love it!

Nice travel pillow
Color: Apricot Pink, Size: S-16 X 12 Inch
Works well as a pillow to support my elbow while I’m driving. It was too full to use as a pillow to place my head on at night since I am a side sleeper. There is no way to remove some of the memory foam to make it flat enough to use as my bedtime pillow. I liked the soft pink zippered cover as it works well and makes it easy to remove and wash. I didn’t notice any smell.
