Absolutely wonderful bed. I gave it the full 48 hours to decompress. Then I gave it to her another eight just to be sure. It is a lovely firm supportive and well-made. Follow the instructions, give it time to fully decompress. If you read any reviews saying the mattress has a dip or have any areas that aren't fully supportive is because that person didn't give it the full time frame. After 20 hours I laid on the mattress just to feel it and I immediately felt a dip. After I gave it 50 hours no dip.
