Cheap material!! the frame came with broken pieces when it was delivered. It took months of me sleeping on the floor for me to finally get the replacement piece I needed but they ended up only sending me ONE of the two pieces I needed so it was still not able to be put together. Fast forward another month of sleeping on the floor and they sent me another complete bed. I set up the bed I had been waiting months for and the slats and support legs underneath gave out and snapped in half. Wayfair sent me a new bed instead of parts this time, I replaced the broken parts again and it was fine up for about five months until the same area and pieces broke once again. So now I have a completely unusable bed (twice  replacement parts for the initial delivery) that I have paid for. Unacceptable. My partner and I are average weight and this collapsed.
