We were disappointed that the "rivets" (for lack of a better word) were inch-long white plastic bars against the black mattress fabric and were worried that they would be uncomfortable.  But after putting a good, pretty futon cover on the mattress and sheets, our guests said it was extremely comfortable and they could not feel the rivets.  Did not have issues with severe smell from the fire retardant chemicals as described in other reviews.  It will do the job just fine.
