I really like it. Great piece of work, especially considering the fact, that you put the interactivity in it as a bonus. I personally wouldn’t sleep well in that bed though…fear of falling really, really hard 
Two things to the technical side of this: i think it lacks a bit of contact-shadowing. From my experience, this results from very sensitive exposure settings (everything from/below Min-Exposure of 0.3) What are your values for Auto-Exposure?
Second to that: Hard to see from the youtube vid, but do you have lightmap-compression on or off? We usually turn it off when working in scenes, that contain many bright/white areas like your walls. Reason for this is, that the DXT-compression tends to result in some JPEG-like rainbow-artifacts. Don’t know if that’s of any help though
