  • Exactly what I was looking for.
    Verified Purchase

    We built a "fish shack" over on our pond for a fun place to hang out and I was looking for two bed frames to place the two twin mattresses on to make them look like they were in a summer camp. The legs are exposed which gives the look a summer camp feel. If you are not seeking that style, these will not work. In my case, they worked out exactly as planned.

  • Not adjustable height
    Verified Purchase

    This is not really adjustable. You can pull the legs off and then you have a really low bed or put the legs on and have a medium bed. doesn't fit to all headboards and you have to figure that out on your own. Either you have to alter the headboard or figure something else out.

  • Nice, Sturdy and Portable
    Verified Purchase

    We bought this frame to set up an extra bed in a nook we had in a spare bedroom. The area we have was just large enough for a mattress but a daybed frame was just a little too big for the nook. The frame is the exact size of a regular twin mattress so it worked well. It is sturdy, well made and very portable. Perfect for our need.
