To soft for a back sleeper and just ok for a side sleeper. I prefer a firmer pillow that I don't sink in. My wife will not even use hero's, it gives her headaches. We took off the zipper covers it came with and took a full week to air out the smell. We also ordered the cooling covers which was a waste of money as well. Since these items are non returnable, we put them in the guest room. We were going to buy a king sized bed but due to the return policy on products. We will be buying elsewhere.
I bought two of these pillows and they did not last long. My husband and I started waking up with neck and shoulder pain from these pillows. There is no support in these pillows. They started out great but did not even last a year.
This is the best pillow Tempur-pedic has produced in years. I believe it would suit anyone. So soft and comfortable, even for those needing neck support.
