Relatively easy to assemble once  you figure out what exactly the diagrams are trying to say. Instructions claim to provide you with 2 50 mm bolts in the list of items section, however they weren't there and nowhere in the instructions did it mention actually using them. This created a little confusion from the get go, but nothing major. Took me about 2 hours by myself. Only needed the hubby to help lift the seat portion onto the frame. 
The mattress material is silky soft so that's a plus. Like another person my mentioned my zipper also came apart when u was getting it in place, but nothing that wasn't a simple fix. Will be perfect as a guest bed, glad I purchased!
