>>dex, wouldn't I have to suspend the couch in midair, since I want it in a second story room?

I was afraid you were going to say that.

OK, solution 1. Have Daffy Duck come over and install a button that when you press it, instead of you going upstairs, the upstairs comes down to you! Press button, do "back in time" thing, take sofa back to the present in correct position on lowered second floor, push button to raise second floor back up into position. As a bonus, you now have a "house of the future!"

(P.S. you'll have to hope that Porky Pig doesn't come over and ask "What happens to the first floor when the second floor comes down?" D'OH!)

Second idea. Bring sofa to past as before. Construct a large metal framework up and over where your house will be. Suspend the time machine and sofa by the framework using thin monofilament wires and position it juuuust exactly above the floor of the second story , right within the bedroom. Return as planned. The wires passing through the roof shouldn't cause a problem I would think.

Come to think of it, I think it would be OK just to build a structure to support it, even just stack it up on boxes, and put the time machine and sofa on top, in position. If the boxes are not inside the time machine, they aren't going to come along to get stuck in the walls.They'll be left behind and someone will move them when they clear the lot to build your house. I think that would be OK. We will have to run some tests to be sure.
