    • Just what we needed!

      We had a HUGE platform bed; heavy and wooden. In preparing to move, I dreaded the thought of moving it. So, I purchased this bed platform for our California king mattress. The frame was a breeze to assemble and supports our mattress well. In moving, I have noticed some bending of the thin metal, but nothing is affecting support yet. At this price point, I wouldn't mind purchasing one every 3-5 years.

    • Great quality, had for over a year

      I got this frame over a year ago for a new memory foam mattress. This frame was easy to set up. I am a 5'2, 100 lb female and I set it up myself. Instructions are self explanatory. With this frame you do not need a box spring and a bed skirt works great with this frame. The frame is very sturdy and does not squeak, it is steel. It is also a decent height because I can still store things under it. When we added the memory foam which is also 14" to the frame, it is really a great height for a bed. It is a basic frame, you can't go wrong.

    • Easiest set-up!

      This frame could not be easier to set up. I am pretty tiny so dragging the box into the house was a bit of a challenge because it is heavy and awkward, however, set up was SO EASY! It unfolds in a couple of steps and was a breeze, might have taken 10 minutes and requires zero tools. It seems pretty sturdy, much more so than a regular frame with an open middle. Like others say, it is a very high frame but it's really meant to be a platform and can replace the box spring, so without a box spring my bed would be at a regular height. I enjoy sleeping higher up and the storage space underneath is great.

    • Works great

      I have two large 8" thick foam mattresses that are used for camping. Usually we put these in the tent on the ground. This frame did exactly what we wanted. The mattresses are off the floor and air circulates around everything. We picked up flat boards for the feet and put two boards on top of each foot holding the frame securely in place and without knocking holes in the floor of the tent. There is no squeaking because we lined the frame with burlap bags before placing the mattresses on the unit. This works for us.
