It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

Very comfortable - spoil yourself! :)

Size: Medium, Color: Grey

Go ahead an spoil yourself! I did, and I don't regret it! I was looking for ways to make my reclining chair more comfortable. This pillow is comfortable and eases the area in the back of your neck/cervical spine through soft, thick, curved support. I also love that it is adjustable in terms of height, depending on whether I'm sitting very upright in the moment or slouching down a bit. Seems to be made of high quality material and has a Velcro strap that you can thrown over the back of the chair (for the height adjustment -- you just put another little piece with velcro on the back of the chair, and that's how it sticks).

Comfy

Size: Medium, Color: Grey

I ordered three pillows similar to this, and this was the one I chose. It was a little softer behind the neck and I think had a little better memory foam feel.

Works well

Size: Medium, Color: Grey

Pillow is good. The velcro strip to attach it to the back of the chair doesn't stick well so constantly have to adjust it. Will buy separate velcro strip and try that
