Fine at 2 months old, then permanent body impressions form

This was far more expensive than a traditional mattress, even with a Serta iComfort sale rebate price in addition to a SAMS club discount. Despite a discount club price and sale, it was delivered by the Serta "white glove" service upstairs to a 3d floor bedroom with removal of the old mattress, box spring and frame. It was fine at first. Maybe a bit too warm but the modern memory foam provided great support and weight distribution , whether lying flat on back or on one's side. But after 3 months it formed what the literature called "comfort impressions." This means body depressions that don't go away--ever. My wife and I both liked the mattress at first but then it quickly formed depressions that reminded us of a +10 yr old traditional mattress at the end of its service life. You got into bed and rolled down into a hole with none of the advertised support--and it was just 3 months old. The original effective and pleasant weight distribution was gone. It wasn't comfortable. We gave ours away to a young couple who needed a king size bed to be able to have room for their dogs and got a new but old style mattress. We'll never buy another one of these foam things. We got an old tech mattress and box springs and love it, even after 6 months. The marketing of these foam things sounded good, and felt Ok for the first 90 days, then turned into junk. I strongly recommend you find an old style mattress manufacturer, with pillow top on both sides. You will be far more satisfied then this hi-tech foam piece of junk with high dollar marketing.
