It said that this fits two people, it does not fit two 5'7", it is too short.  You would need to be in the fetal position.  

The cushions are very sturdy which is great, and the legs for the sleeper fold into the back so nothing is sticking out.  The bottom legs look like metal, but they are hollow, and not well attached to the support.  This is in a guest room and is good for the price and use it will get.
