I bought this and had it sent directly to my aging mother so she could continue letting her faithful and loyal dachshund sleep with her.  Mocha took to it immediately and now this aging pooch can get up on the bed without my mother struggling to lift him.  The only problem is that Mocha can't seem to figure out how to use the pet stair in the opposite direction.

Pros: light weight, sturdy, and folds easily to be put out of the way.
