    • Foam mattress for bunk beds
      Verified Purchase

      Good for younger and smaller kids but when they get older will need thicker mattresses.

      These mattresses are comfortable and the right size. I do not measure them, but my 6'3" son fits just fine.

    • Not long enough
      Verified Purchase

      The mattress was described as being 80 inches long, but is only 77 inches long. Really? They can't make something the size it's supposed to be? This is disappointing, especially since this is a product which needs to work with XL twin sheets, which are made for an 80-inch mattress. At first I hoped it was just still expanding from shipping, but after a week, it still comes up short.

    • Comfortable mattress for a cheap price
      Verified Purchase

      This is a great option for dorms, guest beds, and campers. A little firmer than couch cushions. Thick enough that you don't touch bottom when you sit on it.

      Verified Purchase

      We bought used bunk beds without mattresses off Craiglists. THis seemed like a great buy to have a mattress for my school agae childrens. Shipping was great. The mattresses, though, are hard like the floor. My son complained of neck pain the day after sleeping in them. Will continue to use for now hoping they will soften with time

    • Okay but not Twin XL
      Verified Purchase

      I ordered a twin xl but when I unrolled it, it was NOT 80 inches. This mattress is too short for the bed and it is fully expanded. It looks like the picture but the measurements are incorrect
