Wow...this was easy peasy to assemble. We chose a twin size.  It took no more than 10 minutes to put together. The instructions are clear but we didn't go by them as it was obvious to put together. It brings a malet which made it a breeze thump together. We did not need the legs but would be just as easy to use the malet and thump it to place. The cover is of good thick quality and I like how it brings little ties that you can hook on it so that the cover stays in place. Worth every penny.
