  • No More back pain
    Verified Purchase

    Got this 4 days after placing order. Opened it up expecting to have a smell to deal with but there was nothing I slept on it that evening after letting it expand for about 4 hours. I was a little firm but after the first night I woke up with no aching back I was hooked. I wait for a few weeks before writing this review to see how it would be over a period of time and have to say that I am very satisfied. I bought the water proof cover for it which fit well I just bought a second one yesterday for my wife.

  • Perfect cover for deep mattress.
    Verified Purchase

    We needed a cover for my son's X long twin. Its actually from a split king set of very high end bedding. It is large enough to easily cover the mattress and stay tucked under. It is waterproof as our dog.... We like the material, lack of plastic sound and feel. I thought this was a cover that would go over both sides. The description does not say, but it is basically a waterproof fitted sheet.

  • Not what I thought I was ordering, but my error
    Verified Purchase

    These seem to be fine, but they are a rubberized mattress cover, not the quilted cover that I intended to buy. They'll be ok, since it's for my guestroom beds, but I'll probably be picking up quilted covers to go over top. they do not appear to be too noisy, which is a good thing, but I'm wondering if they'll be hot.
