  • 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.

    Shopped locally. Didn't find anything impressive. This is a great value compared to all others we found.
