Recently received and haven't used ye.  Chaises (I ordered 2) were easy to assemble, all you need to do is install arms.  I did it myself, even though instructions suggest 2 people, but I thought how hard could it be?  I think if it were 2 people the assemble time would be less than the 45 min it took me.  I had my husband tighten the arms after he got off work.  My only issue, if you can say that, is the front "feet" don't lock in place.  If you want to move it the lounges to a different location, the front feet will collapse....just annoying but not a big deterrent for me.
