Pillow is very thick and does not compress much with weight. Holds me slightly too high. The odor eminating from them was awful though. I was finally able to use it for the first time after three weeks of wipe downs and airing them out.
The pillow is manufactured to excellent quality standards and is noted to be firm but I find it extremely firm compared to other gel memory foam pillows.
Do not buy this awful smelling pillow, first 2 months back ordered. Then when shows up smells like chemicals and after sitting in open air still can't be used the smell makes you sick.
