Bed made to order - Twin XL

My daughter has a twin XL bed, which we had been unable to find a frame for since getting it. After 2 years of her mattress and box springs on the floor, this plan came out and a plan was hatched to get it made. The biggest change we needed to do different from the twin plans was to make the side rails and the side rail cleats 5" longer to accommodate the XL length. We also added a middle support to keep the side from bowing out, and the cleats are at the bottom of the siderails, as we are using a boxpsring and mattress.
