When I bought this ottoman they were selling an optional tray that was quite expensive. I had some leftover barn board so I decided to make this simple tray
Wood type: Grey Barn Board
I cut four pieces on the table saw and then joined them together with pocket screws. I made to edges so that the tray would no shift on the ottoman. Once again, I attached those two pieces with my Kreg jig (no I'm not sponsored :).
