We are very pleased with this mattress. We slept on a foam mattress with cooling gel on vacation and loved it. After contacting the hotel, their mattress was going to cost us nearly $1000 with S & H, so we looked online and found this one that seemed to match its specs.
The smell was gone quickly - by bed time after unwrapping. After about 5-6 weeks sleeping, its seems great. Our only reservation, is that the cooling gel does not seem to work as well as the mattress we tried at the hotel. Its definitely not as hot as a straight thermal foam mattress or mattress pad, so I'm glad about that.. We've tried those, and I thought the world was on fire I got so hot!
Previously, we had a high end Sleep number bed. We HATED it. No matter how we tried to configure it, we were sore and uncomfortable. There was never an "ahhhh" factor when we got into bed at night. Now with this mattress, we have that "ahhhh" factor. The best part, is we were able to keep the adjustable bed base. We can raise and lower the mattress like a hospital bed.
Update: 2/12/2017: We have had this bed for 4 years now. We still love it! Best bed ever!!! Still a little too warm, but every night we climb into bed and we still have that "aaaahhhh" factor. Sleeping on an old fashioned coil mattress sucks. We hate sleeping in hotels.
