With 4 people, we were able to put this together in about 2 hours. The directions are pretty straight forward! I will say, however, that we were a little disappointed to find out that the drawers do not run on a track, they just sit on the ground with wheels. They are still useful though, so we are happy. 

I'm rating this a 4 instead of a 5 because after only 2 days of having this futon, the mattress already has a slight rip. You see in the photo 4 "dots" on the mattress, where a button is sewn onto it. This button ripped off our mattress after only 2 days of having it put together. It's a small hole, and shouldn't interfere with us as long as it doesn't widen.
