Purchased 2 of these to replace a one-piece seat and back cushion of my Mother's porch swing.  Measurements are true to size and they worked perfectly for the seat and the back.  Color  (wheat)was a little darker than depicted, but that could have been my display.  Love that I'll be able to unzip and wash the covers, as this was the reason the old cushion needed replacement.  Only been on for 2 weeks, so if anything changes, I'll update.

Pros: Durable, heavy duty, good quality.
Cons: Only two ties on the cushion - one on all four corners would be nice.
