I will begin by saying I like a firm mattress. I was also very skeptical of any mattress that came in a box, but I moved into a very old house with STEEP narrow stairs, so I was forced to consider this one. I am glad I did! Never having had a foam mattress, it took a few nights to get used to it, but I have had it for several months and I will not go back to a spring mattress. This is NOT memory foam for those who think it is (read the description. I can't stand memory foam anything so I wanted to be sure this wasn't.) It is firm, so if you want something cushy and soft, this is likely not the mattress for you. Its held up well so far and I sleep on it every night. I am about to get a new bed, and was thinking of buying another to use as a foundation.
