I have put a lot of furniture together and I’m always prepared for sketchy instructions, mis-fitting holes and screws, missing parts, or damage during shipping.  However, this bed had NONE of those issues, amazing! It was perfectly wrapped and marked so assembly was really easy. Everything fit together perfectly! It is sturdy as heck, there are cross bars to support the mattress and little rubber spacers that hold the supporting bars in place. I will definitely buy product from this manufacturer again, what a pleasure. Took a little less than two hours to complete and I did it by myself.
