    • Pleased with product

      I inherited a roll-away folding twin bed frame without a mattress. The appropriate mattress was impossible to find in local stores. I was a little apprehensive about purchasing this mattress without being able to see it, but I was desperate. My young grandson was due to visit in one week so I took a chance. Well, I was pleasantly surprised by the thickness and density. I don't know if would be comfortable for my old bones, but my grandson slept comfortably on it for a week.

    • Worked perfectly~

      I needed a firm, thin twin size mattress to turn a brass bed into a settee. This one is very firm, exactly the right thickness and appears to be substantial for my needs.

    • Good mattress

      I am a big advocate for foam mattresses. Got no complaints about this one. The five year old sleeps well on it!

    • Good buy!

      Good product, came as expected- quick shipping. Not that it mattered to me, unlike other (more expensive) foam mattresses, the mattress cover on this one does not have a zip (so foam cannot be cleaned without tearing apart the cover)
