Wow! What a mattress! I have been sleeping on the mattress since the first night it arrived (early June, I think?)-- so for about a month now.
I had been a stomach sleeper most of my life, but after a back injury, I was forced to be a side sleeper. With this mattress, I can lay on my stomach--for chilling, reading, playing on laptop/tablet-- and sometimes even sleeping! My weight (currently about 230 pounds; big hips, large breasts, broader-than-normal woman-shoulders) is evenly distributed and supported! I have fibromyalgia, along with several other health conditions, all of which contribute to me having sleep issues & "getting comfortable" is a struggle. . . but this mattress has made a positive difference! Right now I'm sitting on it, with my feet and part of my legs hanging over the bed (which I've done before)-- this position typically puts my legs and feet asleep fairly quickly, but not with this mattress! The pressure on my calf muscles doesn't cause me pain! Even sitting without leaning against anything, I feel supported and my butt doesn't hurt!
