Pro: Easy to assemble but tools not included. You need a small wrench and a mini screwdriver and extra washers. Cons: 1. filler smells like a car oil tank and is not enough, so it makes you feel the steel support, 2. you can see the screws unless you paint them with a black marker, 3. once assembled, it does not cover the frame. We kept it for the frame since the cushion is replaceable and is now in our basement bar/game room
