I bought two sets of Restoration Hardware cushions on clearance and they worked out great. I had to adjust the measurements a little bit but that went pretty quickly. I came up with a plan for the tables to match the couches.
The tables are both 30x30. This way I can use them as 2 tables, one large table, ottomans or seating.
I LOVE the cushions. They are 6.5 inches thick and were dry 3 hrs after a rainstorm. There was no way I could have sewn something cheaper.
Thanks for the plans Ana!
