I ordered the California King size. It fits the mattress perfectly, is sturdy and well-constructed. I didn't believe that assembly, as described, would be "easy" but it was! No tools are necessary and it was assembled in just minutes. With a metal frame, I worried about squeaking and creaking, but this frame is so sturdy that there is no squeaking at all - a real plus for light sleepers. The 14" height is enough room to store luggage or other items under the frame. I wish the legs had rubber stoppers or some other protective cover, but that can be added. [...]This was an excellent purchase and I'm quite satisfied with the product. I've only been using it for a couple weeks, but I think a problem would have shown up by now.
