I explored many options for a murphy bed for my den/guest room, and spent quite a bit of time considering this one.  I read all of the reviews (most of which were great) and was a little nervous about return shipping if it didn't work, but I'm so happy I bought it.  It's a great looking piece and it's so versatile.  The fact that it's on wheels and is quite compact makes it a great option for small spaces.  It's sturdy and the mattress is substantial.  It's quite firm, but I would rather that than too soft.  I was fortunate that it arrived in perfect condition, after reading many reviews about broken hardware.  The only negative about it is that the mattress has a very strong odor.  I've aired it out for days and it still isn't gone, but it will fade.  If you're unsure about committing to it like I was, I can tell you that I'm very happy I stopped debating with myself and purchased it!
