    • Great idea, not 100% awesome on delivery.
      Verified Purchase

      VERY easy to setup and rather genius design, mine came missing a rather critical butterfly nut that I had to go to the hardware store to fix. Overstock covered the cost of my quick fix. When setting a King or even Queen mattress on this frame I STRONGLY recommend two people, otherwise the frame "sheet" that's included gets bunched and is useless...it's basically useless anyway but a good idea. Great height and like I said quite easy to set up. No tools required if you don't use a headboard.

    • Great frame!
      Verified Purchase

      This frame goes perfectly with the matching mattress. The cover for the frame doesn't fit as well as I would like but the frame itself was very way to assemble and it only took about 20 minutes. Very sturdy. And high enough off the ground that we can have storage under the bed.

    • Height not in description
      Verified Purchase

      The description said 12-14 inches high. Also it said "adjustable height." There are actually only 2 heights. 14" and 10." There is no 12" height. I bought this to go down a couple of inches, but the clearance at the low level is only 9" which is not enough for a banker box. 11" would have been perfect because a banker box is 10.5 inches high. Even these small differences matter. They should have been more clear in their description. I would have probably bought another frame. The only reason I picked this one was because I thought it was adjustable to 12." My bed is a little high because I put a memory foam pad on top. Oh Well, I won't even use the lower height! And this just means that the frame has more unnecessary movable parts.

    • King size bedframe

      This requires no tools, folds out easily & just tighten the wing nuts. Raises the bed high enough for storing boxes etc. & who can't use more hidden storage space. Makes the bed sleep like everything's new. Would buy again!! Steel frame holds at least 2000 pounds!
