Read over 100 reviews on this futon mattress before purchasing. i was nervous about trying to return item because of the size it expands to. turned out to be an excellent value for the money. fits perfectly on my frame - folds up easily from bed to couch position. very comfy in both positions. i did not experience any strong odors as some have. i did febreeze it though just in case. of course its not the quality of a permanent mattress one would purchase for a regular bed (and pay over $1000.00 for) but is great for overnight guests and as additional seating. i am very happy with my purchase and of course the free delivery. can not comment on the longevity of item at this time.
