We bought this bed in December to replace a sleep number bed. We wanted to move up to a King size and didn't want to go the sleep number route again for a variety of reasons, primarily motion transfer. I tried memory foam beds in mattress stores and was a bit worried that they would be too hard. I like a very soft bed, my sleep number was 30-35, but my husband likes a firmer mattress, he was a 45-50. We ultimately ordered this bed in soft and although it feels a little too firm when you first lie down, it feels perfect a few minutes later. I do not have any back pain or stiffness when I awake and sleep quite well. There is no motion transfer and we have not noticed any indentations when we get up. The bed quickly returns to it's original shape. The smell everyone refers to was evident for about 2 weeks. We opened the bed up in our office and left it there til the smell faded. For the price, you CANNOT beat this bed. I was skeptical about buying a bed online, but we LOVE it!
