Our futon mattress had worn down and was no longer supportive, and I am very happy with this Aviva 7” Cold Foam Full size mattress.  It arrived quickly and was completely encased in plastic wrapping.  The mattress is firm and supportive for an adult so the metal bars of the futon frame cannot be felt.  II like the deep blue color and the upholstery weight of the fabric. 
   Sleepers may need a foam topper for comfort if they are not used to a firm mattress.
