Unfortunately we returned this mattress after trying it for about a month. It was just toooooo soft for us. Now, we love a soft mattress, but when you sit on the edge and practically fall off because there's no support, that might be a problem. I left for a work trip where I spent 4 nights in a hotel and the shoulder pain I hadn't realized was caused by the soft mattress magically disappeared! Upon returning back home to this mattress -- and to the pain -- I knew we couldn't sleep on it anymore.
