Our house was built in the 20's. A few years later they closed in the "sleeping porch" and we now have a beautiful round parlor with five 5X7 windows, walnut french doors into the living room and a big closet that holds a "real" Murphy bed, with a tag that says 1915. The bed turns out of the closet so easily, then it folds down. We bought a full size mattress from Sears. I spent 7 weeks on it with a broken ankle. Our old house really only has 2 bedrooms, but this was advertised as a bedroom, too. I prefer to call it the parlor/guest room.

Screw/glue a ledger strip to the insides of the rails to support the ends of the slats--don't route the siderails out.

We have this bed and the leather headboard (with the drawers rather than the baskets) that we bought through Craigslist about 6 weeks ago. I love it. We really needed the storage (just downsized to a home half the size of our old one) and the drawers are huge (we have a king). I don't find it any more difficult to make the bed than we did with our old bed. I don't have pics as our bedroom is still a work in progress. We knew we wanted this bed and were thrilled when one popped up on CL right before we moved.
