After we moved the mattress upstairs there was a big hump, bump or lump in the middle.
We call the company and they said they never had a complaint about their mattress seem like they do not listen very well. We did find out from this web site that to get rid of the hump you had to cut into the mattress. We hesitated to cut into it however, we could not sleep on the mattress any more.
We final did cut into the mattress just enough to get our hand inside. First above the stitching which did not work because they place a lay of cloth between the Gel Foam and the Top Foam. Once we could reached the foam we pulled it back and no more hump. GREAT ADVICE GOOD LUCK
