Was very easy to put together. Ordered a king and was nicely surprised that it had 2 vertical beams with 4 legs each for added support.  Only complaint was the off-gassing smell of the materials.  I understand this is due to them needing to be fir-retardent but am trying to rid my home of toxic materials so this was an unwelcome surprise. The smell did dissipate within a day.  Very sturdy so far.
