Becaue the assembly directions are not very helpful, it was on us to figure it out. It wasn't hard but it did take some time. The first chaise took about 45 minutes to assemble. The second only took about 15 minutes. Don't be alarmed when the box arrives! It looks like it couldn't be possible to have the entire set in that one box but it is! We're happy with our purchase! (Delivery took less than a week.)
