Assembly was very easy- except my package did not include the Allen wrench.  My instructions flew away while I was looking for an Allen wrench in my drawer () so thank goodness the assembly was very simple!! 
These are very lightweight- I’m not sure how long they will hold up.  I also dislike that the stitching is crooked (see couch photo).  The table glass does not fit well into the table and there is no way to secure it or the cushions.  I don’t expect the glass and cushions to last an entire sunmer.  
Overall they aren’t terribly uncomfortable if you are small.  My kids love them.
