The bed is finally finished! A hatch cover was cut in for easier access to the system water control valves, the queen size mattress was unpacked / unrolled / allowed to expand, and the linens were put on. Wow, this is a good feeling bed! I can't wait to actually get a night of sleep on it, but the initial tests feel great. Here's a few pics...
