I read nearly every single review before I made my purchase. Few people mentioned their weight, so I want to say that my husband weighs 250 , 6'4" and I weight 135 5'7". i mention this because with my old Serta mattress, when my husband woud get into bed, I would roll to the center. I was concerned regarding this purchase because I wanted to get something to support his weight and be comfortable for me. I am so glad that I read the reviews and ordered the SOFT mattress. Even though it is great, the soft is firm, so I shudder at the thot of ordering even the medium. I am very pleased. My husband says that he didn't realized that the old mattress was making him feel stiff in the mornings. He thot that he was just getting old. Now we both feel so much better in the mornings. My old mattress was so uncomfortable that I was staying up later and later because i didn't want to go to bed. Not to sound like a commercial, but I love settling down in my bed now.
