I want to see a video of it lowering and raising the bed. I can kind of grasp it from the pictures but it would be cool to see.

Does seem like a nifty idea, but what if you loaded it up with more weight than it could hoist back up into place? I would guess they've dealt with that.

Something tells me it could be a problematic mechanism. A lot going on there.
