The pillow is comfortable and supportive. The cool gel only stays cool for about 15 minutes, but it's usually enough to fall asleep. It does need several days of airing out before the foam smell subsides enough to use.
I have other memory foam pillows and a memory foam mattress. The price of this pillow is great and it seem to be a little larger than some of the other brands (diameter). I do wish it was a little thicker but that is just me. I am a side sleeper and could use a little more neck support. I can't say I notice a difference in the coolness but I do have a zippered satin pillow case on it over the cover that came with it. That could be blocking the coolness.
The Cool Gel Comfort Pillow keeps your head cool on those warm nights. Constructed of durable memory foam which gently cradles your head and neck, this pillow features a layer of cool gel which helps regulate your body temperature.
