Perfect adjustable bed frame!  There are lots of various of basic metal bed-frames that used to be called a "Harvard square frame." I bought this one to hold one of Wayfair's simple folding box-springs and a good quality 10 inch Queen memory foam mattress (plus a 3 inch memory foam topper). I'm on a budget but well past the point of buying junk that will fall apart. This frame does all its supposed to do and has the center rail for extra support (some are just square).  It also has wheels that lock (some don't have the extra support rail or wheels).  It was very easy for my adult daughter and boyfriend to put together and she could have done it herself (I can't but that's because I have disabilities in my hands). Highly recommend!  I just moved to a larger home and got a ton of new furniture from Wayfair. I am about to buy another of these for a guest room with a full size bed.
