This is not the same quality as the TempurPedic pillows we are all familiar with. Those are 4-5 lbs in density; these are 3 lbs, and there is a big difference. The material is not as soft, and it does not hold the shape in the way that high quality memory foam is known for. The "Oversized" shape of these pillows is also less comfortable than the expensive ones I have tried in stores -- they feel like overstuffed pillows. On my traditional mattress, they worked OK, but when I upgraded to a (flatter) memory foam mattress, they were MUCH to high. They are also not tall enough in the chin-to-forehead direction, so my head does not fit comfortably in the hollow. Finally, these pillows do not come with a fabric cover, so they have a very cheap appearance. They do basically fit in your average pillow case, but they look like the inside of couch cushions. I would highly recommend shopping around some of the other higher-density options on this site before buying these. They are very cheap, but probably not worth the money.
