    Came super fast! Bought this for our granddaughter's room since she has a loft bed now. Fits well and just the right height so we don't have to worry about her going over the side! And a great price!

  • Perfect for trundle
    Verified Purchase

    I took a shot on this based on the good reviews and was pleasantly surprised. I wanted an extra mattress for a trundle for when guests stay over. I wanted something inexpensive which was hard with a regular mattress as the cheaper ones tend to be really springy. I like the thick foam of this one. It's very comfortable. Feels firm to me but I'm only 100lbs and enjoy a firm bed. Someone heavier may sink in a little more. My husband is about 160lbs and said its comfortable for him as well. It does come rolled up in a box so you need to let it air out/expand over night. I would definitely recommend as an extra mattress option!

    I inherited a roll-away folding twin bed frame without a mattress. The appropriate mattress was impossible to find in local stores. I was a little apprehensive about purchasing this mattress without being able to see it, but I was desperate. My young grandson was due to visit in one week so I took a chance. Well, I was pleasantly surprised by the thickness and density. I don't know if would be comfortable for my old bones, but my grandson slept comfortably on it for a week.

  • Worked perfectly~
    Verified Purchase

    I needed a firm, thin twin size mattress to turn a brass bed into a settee. This one is very firm, exactly the right thickness and appears to be substantial for my needs.

    I am a big advocate for foam mattresses. Got no complaints about this one. The five year old sleeps well on it!

  • Good buy!
    Verified Purchase

    Good product, came as expected- quick shipping. Not that it mattered to me, unlike other (more expensive) foam mattresses, the mattress cover on this one does not have a zip (so foam cannot be cleaned without tearing apart the cover)
