See last post.
So the service guy came out. He was able to lower the bed portion of the sofa an inch, which was as far down as it would go. Then he found some cylindrical legs, which were slightly shorter, that look like they belonged to a different type of furniture. After making those changes, the bed is only elevated slightly. We have decided it’s good enough. What boggles my mind is that even with the bed screwed in as low as it can possibly go, it’s still clearly not right. The only possibilities I can think of are either (1) they put the wrong model bed into the sofa, or (2) the sofa has a fundamental design flaw, and they’ve just decided to sell it that way.
