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.

Great little pillow

Color: White & Light Blue, Size: S - 16 x 12 Inch

Works perfectly since stuffing can be removed to make it just the right thickness needed for you. Soft & cool to put your head on plus very well made with quality materials.
