We love this futon.  It was the perfect addition to our spare bedroom without having to purchase a whole other bed.  The mattress is surprisingly sturdy and comfortable.  It is somewhat difficult to put together; however, it is solidly made, in my opinion.  I definitely recommend!  

Pros: Excellent value for the price and shipping; appears to be quite durable.
Cons: Difficult to assemble; not super easy to switch from couch to bed.
