The trays are a great addition that puts this ottoman over the top. The trays are so nice I would buy them separately if they were available. 
It comes out out the box fully assembled which is a great bonus. It is a little on the small size but perfect for the loveseat I purchased it for. The only issue preventing five stars is that there is a very strong smell inside the ottoman. It needs to be aired out for a couple of days before you would want to put a blanket or anything that might pick up the smell in there. Definitely worth the price.
