My experience is that it works very well, but I sometimes value the raw elevation (as David commented, it makes it easier to get out of bed in the morning). I also find that clutter on my floor is more annoying, so I clean more often, which has it's positives and negatives - in a small space it can be annoying since the clutter has no place to go. And, of course, dust/mold/spiders/cats are more annoying.
