We have been using this bed frame since November of 2016. It is very sturdy. It was easy to assemble. The instructions were clear. My dear hubby and myself assembled it together when we received it. Assembly took a little over an hour. We are using a 13' mattress with the frame. You can use a box spring with it if you choose. We moved and had to take it down, store it and then put it together again in the new house. Hubby put it together himself that time.  There are many parts to the bed. I would suggest that two people assemble it due to the size of the frame and the many pieces. We have the king size. The poles that form the hold for the mattress are very strong. The metal frame is strong as well. Everything came as expected and it was actually delivered before the due date. I assumed it was because of the holiday delivery schedules. We are very happy with our purchase.
