We upgraded from a queen size bed to a king size. We pondered buying a frame but I had confidence that I could build it better and cheaper. One of the challenges I faced was that the upper bed frame only had about an inch clearance from the height of the door frame so I had to build it in the bedroom on carpeting which is a challenge keeping everything square. Propping it up on boards took care of that issue and everything came out square. This is the biggest project I have built yet and learned a lot about structural stability. Everyone who has seen the finished product thinks we bought it from a store. I would not have been able to build this without my collection of Ryobi tools! Every tool worked flawlessly and effortlessly throughout the entire project. Thank you for building reliable and affordable tools.
