Here is another transforming piece of furniture that can be converted from a couch into a bunk bed for 2 people. The Dormire Couch is pretty easy to use: simply lift up the seat base for the whole system to rise up. Once you have locked the bunk bed in place, you can use the built-in ladder to reach the top bed.
The Dormire sofa measures 88.2 inches wide x 36.22 inches deep. Expected to ship late December.
