We have been looking for a deal on an outdoor sectional for a whole year. Nothing. The cheapest we could find was $899 for one that was much smaller than this one and with thinner cushions. So we upped and drove to the lumber yard and purchased the lumber on the list and got to building.
The total cost of lumber was $200, the Spax screws we already had on hand. We used pocket holes for the joints. The wife made the cushions herself. She had most of the fabric on hand, we just had to buy 3 yards for the back cushions, which are made of standard size pillows. They have been sprayed with fabric protectant for outdoor use (I think she used the Scotch brand). The seat cushions are 5 inches thick (they are wrapped in silk film to protect them from getting soaked when it rains or when someone who just got out of the pool sits on them), around $100 for both. It took her a couple of days to sew the box cushion covers.
