      Mattress is much to big for a regular twin size bed.

    • Comfortable memory foam

      I put these mattresses in twin beds in the guest bedroom. My college-age and young adults kids say it is comfortable . They're happy with them when they visit .

    • Comfy Mattress

      I really like the mattress - the only thing I wasn't pleased with was the mattress cover. There was a small tear in one place, there were a lot of loose threads, and there was a big dent on one corner; seemed like the foam had somehow gotten stuck to the cover, so pulled at it and got it loose. Fortunately the cover doesn't get taken off, and with a nice mattress pad it's fine - just a little disappointed in workmanship

    • My daughter loves it.

      It was one of those blind purchases: we needed a twin size mattress for my daughter, and had a limited budget. Mattress stores did not have anything decent to offer for the money. This mattress was not only at a good price, it has arrived super quickly, and my daughter finds it very comfortable.
