My husband and I weren't sure if we would like a foam mattress after laying on them at mattress stores, and several thousands of dollars is a rather expensive way to find out. So, when I saw this for under $500, I figured it was a great way to find out!It came very quickly, packed very well, and we have been using it about 2 weeks now. We do like foam mattresses, and I am now thinking about upgrading to a thicker one. This one IS very thin. It is only about 6", and on our box springs, we have a VERY low bed now. It is comfortable, though, and we have a lot less aches and pains.So, bottom line, if you are experimenting to see if you would like a foam mattress or not, this is the way to go. If you already know you like a foam mattress, spend a little more and get one of the thicker ones offered here.
