    • Great Value

      Comes tightly packer in a small box. Let it air out when you unwrap it, and like magic it expands overnight to full size. Very comfortable. Bought for XL twin bunk bed--great deal

    • Love this product!

      I used these 2 mattresses for a built-in bunk bed & since its very difficult to make the beds, I wanted something lightweight. Very pleased with the quality & the products arrived quickly & on time. My grandkids say they are very comfortable.

    • twin sheets fit

      I bought this mattress for a twin extra long bunk. I wanted something inexpensive as we have wetting issues. I like this mattress because it is lightweight and easy to move around, and the lower than standard height is good for safety on the top bunk. I was surprised and pleased to find that the twin sized fitted sheets we already own fit easily on this mattress. I think it is because the sheets are made for a standard 8" height and this is only 5" high. I am pleased to not buy new sheets and in particular to not by twin extra long sheets.

    • Awesome mattress! Plan to buy more...

      Bought this mattress for my husband who drives truck to replace his coil-spring mattress in his semi. He is very happy; the coils were tapping his heat and aggravating his back; this new mattress is a huge relief. We will be replacing all our children's mattresses with these!

    • Overstock only shows me sheets now, haha

      I find it amusing that only sends me ads for mattresses I already bought and sheets I already own. The "new" way of directing traffic on the internet. Funny! Maybe I would want something else, you would think. But ads for mattresses, bed springs, sheets are fine. I certainly won't buy any more of them!!! It will save me lots of money $$$$$ !

    • Comfortable mattress for a cheap price

      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.

    • Okay but not Twin XL

      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

    • Not long enough

      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.

    • OK

      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

    • change instructions

      I purchased this for my sister who has an old hospital bed and needed the x-long size to fit it. We tossed out her old matress thinking the foam would inflate in the 48 hours like the instructions said. (she does not have a car so I had to do this while there) It was almost two weeks before the matress filled out to the size it was supposed to be. Thank goodness she had a cot to sleep on while waiting for this to happen.
