Very simple to assemble.  Pull out of box, open up frame, push support legs into position, attach a couple of screws, and your done.  Lots of storage underneath (can slide our large suitcase under with no problem).  Bought a 12" memory foam mattress for this frame and have been sleeping on it for nearly a week.  No shifting of mattress (though we did put a mattress pad between mattress & frame), no "squeaks" from frame when turning in bed.  Will be purchasing another of these frames for guest bedroom in near future.
