So this couch looks awesome and I (female, slim built) was able to assemble this easily. 

We planned on using it as a guest bed for my parents but this will not comfortably fit two adults (regardless of their size). In an emergency, certainly but you'll be really, really close. Like REALLY close. 

However, that would have been doable but no matter how you lay, your feet will be dangling over the edge. I'm on 5'8 and couldn't stretch out comfortably. So as a couch in the garage/hobby room, it's great. As a guest bed for two grown adults who aren't super short, I'd give this one a miss.

The grey linen looks nice, though.
