Overall, I’m happy with it now. I was not, when it took us a couple hours to put together. The directions weren’t the best. We got 3 sets of generic instructions, one for the frame, another for the side and bottom rails, and another for the headboard that are supposed to work for any type of bed this company sells. A couple of the holes for the wings didn’t line up, but luckily they are esthetic only and don’t actually support the bed. 
We have a regular profile slatbox and mattress and there is still about 4-5 inches between the top of the mattress and bottom of the head board. No way to lower the headboard, especially with wings. 
The support rails underneath seem sturdy enough and I’m glad that they came with levelers. 
Love the look, but I would think twice about ordering something that requires this much assembly again.
