Very good quality hence the heaviness of the unit. Instructions were easy to follow. Everything fit together very well and the only bolted connections were the seating units on the sides (4 boltnuts per side). Aside from being impressed with its fully completed fit, its operation and the overall look of the unit, we were really impressed with the welded steel cages used to package the two boxes the unit was shipped in. Very sturdy and well planned out packaging!!  Highly recommended.
