Yup, it was 29 X 70, which is after I took an inch and a half off of the length. Now it tilts upwards much easier to get to the storage compartments, just clearing the window frames but still wide enough to reach the outer edges of the cusions.
I made the legs as high as the ledge on the front wall plus the height of a 2 X 4 on edge (usually 1.5 inches milled, but measure to be sure), which made it all level. However, another 3-4 inches in height would be better now that I've seen it in use. Just barely enough room for the bottom sleeper to comfortably roll over in its current configuration.
The legs at their current length are about a half inch too long to get the thing through the door in one piece - still. The first leg through the door has room because you can turn the whole thing but by the time the 2nd leg needs to come through you can't turn it because of cabinets on the far wall. I'm considering adding hinges and buckle latches to allow the legs to fold up but for now I'm leaving it as a semi-permanent installation.
