I received the mattress in good condition I gave my mattress a full month to inflate and thinking perhaps I needed the full month to adjust. But after a month one side of my mattress has only inflated to 10.5 in while the rest of it inflated to 12. Then we noticed that when we try to sleep on each side of the bed we tend to roll more toward the middle of the mattress instead of staying on the side that we have positioned ourselves on. Around the edging of the bed you can feel the u-shape metal bulging out I dont know if that is supposed to be the edge support that this mattress is supposed to have but it is uncomfortable while getting off the bed cuz you can feel it poking into the back of your thighs. Overall the bed is a wonderful bed if you get a good mattress but the king size I ordered was not up to par for what I was looking for.
