this is an awesome mattressfor the money. We received the bed within four days of ordering! VERY FAST delivery. There is a sight odor to the mattress, but it will dissipate over time. When I first lay on the mattress, I thought uh-oh, too hard. After lying there for about ten minutes, my body heat expanded the mattress more and it was perfect. After a day of taking apart old beds, moving up new bed, asssembling, running to hardware store, and hauling new memory foam upstairs, I lay down with my son after his bath to check it out. I fell asleep for about two hours!! this is a great deal. Buy one immediately if you are interested. I may be getting the king sized version for myself very soon!!
