    Verified Purchase

    When I recieved my mattress set, I couldn't believe how firm it was. My old one was lumpy and my fiance and I had a very hard time geting any rest. As soon as we set this bed up, there was no longer any reason to complain! We slept incredibly sound that night and have ever since!! I love my purchase!!

  • Best Ever

    Firm. Comfortable. Two houses. Two if these. Doesn`t wake her up when I get up. Room for the kids when they can`t sleep.Tried every brand out there. You have to lie on these. Not just sit on them to test them out. That`s why bozos give bad reviews. And our body changes over the years so does our comfort zone.

  • Don't buy it
    Verified Purchase

    I bought this mattress and it makes a lot of noises, when you sit, move, when you are sleepping it wakes you up, I didn't have time to call overstock, I call one day before the 30 days and the miss told me that the warranty with them has expire, that I need to call spring air, but has been impossible to contact them, I'd prefer my old mattress 100% times than this one.

  • Low Quality Bed and Mattress was not Frim
    Verified Purchase

    Bought this bed and mattress combo 1. Took 2 months to receive it 2. Bed looks expensive and is pretty quality wise it is unacceptable we had to go to Lowes twice to purchase brackets + large plywood to make it stable 3. Mattress first arrived damaged, 2nd time after 2 months of total waiting time got the replacement 4. Advertised as BackSupporter Firm it feels super soft. We had a SpringAir mattress from before and it was solid, this model feels like a extra soft mattress. 5. Customer Service has been acceptable, the quality of products was low. I guess you get what you pay for.
