Assembly involved attaching 8 legs, 4 each side, and then connecting the units by barely lifting one side and sliding its metal joint into the other side. I assembled it myself in less than 30 minutes and have fallen in love with it, especially it’s green color! If you have other things to do, like moving in other furniture, don’t assemble until after all tasks are complete because once this beautiful couch is assembled, and you sit on it, nothing else gets done that day! It’s wonderful! Best investment ever!
