UPDATE: After about 30 days, the rail cracked. Once again, customer service through the manufacturer has not been helpful. It was easy to assemble, but the holes were drilled incorrectly and I had to repair this myself. The base supports for the center beam are also too short and don't reach the floor. Contacting customer support from the manufacturer was no help - they are only available M-F 8-5 ET, not 24/7 as listed on the flyer enclosed with the package (but you can reach their answering service instead). Once assembled, I found that the quality isn't quite what I was hoping for, as the materials seem lightweight. The bed rocks a bit as well. I suggest adding a sheet of plywood or something similar above the slats to add more support. While I think it'll be fine for the time being, I doubt this will last in the long-term.

The right side rail has a crack all the way through and the support legs are about 1/2” off the floor. Not as sturdy as I expected and the color is not perfect on the foot board.

What a nice bed for our spare room. The walnut finish is a great departure from all the oak finishes we had in the room.
