Wow! This living room set is precisely what we are looking. It replaced a faux leather, brown hulking 3-piece sectional. The set arrived in two large and heavy boxes delivered inside our home. Delivery was scheduled and arrived on time, even received a courtesy call with real time location update! Legs and hardware were stashed in a zip pocket underneath each couch. The set took myself about 45 minutes to assemble. They are built very sturdy although lightweight. The cushion may feel a little firm because they are new out of the box and have not been broken into, so to speak. The legs screws onto the bottom of each couch and a corresponding set of bolt, nut and washer then further secure each leg in place. The backboard mates and slides into the side rails located on opposite ends of the couch. If the backboard keeps "popping out," then you've incorrectly installed the backboard.
