    • 12" cal king
      Verified Purchase

      Great quality mattress for the price! Purchased to replace a waterbed mattress in a hard frame. Fit perfect with enough depth so you don't hit your legs on frame. A bit more firm than expected, but I am still getting used to it. Very comfortable. Would recommend.

    • Awesome bargain, price and comfort!
      Verified Purchase

      Very pleased with my purchase, at first a little apprehensive of course but couldn't beat the value in comparison to my mother in law's. (She paid $900 for her queen size vs our cal king!)

    • purchased this a few years ago
      Verified Purchase

      and still very happy with it. Still feels just like it did 5 years (or however long ago it was) ago when I bought it. I was dubious about how they were going to ship it and when it came all sucked up in a bag I thought "No way is that going to pop back to a 12 inch cal king size....but it did.

      Very hard at the beginning; have tendency to deflate at the edges causing potential for fall injury.

    • Love this mattress!
      Verified Purchase

      My husband and I are both heavy people and worried the firmness wouldn't be enough. Boy were we wrong! Love the mattress!!!! You only sink in a little and it popped out and air out to a full 12" within the first 24 hrs. Totally recommend this item.

      • A:

        A couple months ago we were moving and didn't want to store our mattress in the barn with the rest of our stuff so we actually managed to squeeze it into our motorhome and into the bunch over the cab. of course it stuck out quite a bit as it was a calking size and 12 inches thick. I slept up there for 2 months and had to squeeze in there, but it worked and when we got our new house we wrestled it back out and up the stairs to the new room.
