I've had this bed frame for 3 weeks now, so here is my honest opinion. The wooden support frames are NOT pre drilled and they DON'T recommend power drills. Had a nasty forearm pump after I finished screwing the boards. Unfortunately, I was conducting the "deed" and the wooden support frames broke. Please see pictures. I literally followed the instructions and I was quite surprised. I only weigh 150lb. Maybe I got a defective unit. Slightly disappointed that they couldn't simply ship and replace the broken wood, they wanted me to send the bed frame back (I told them I didn't have the original packaging) in order to be eligible for a refund. The frame is beautiful, but the quality can definitely be questionable. I'm not happy, very disappointed.
