Although we have only had our new cushions for the chairs around our fire pit for a week, the Sunbrella fabric seems very sturdy and comfortable. We chose dark gray and love the color for our patio. The bottom cushion is very firm and the back cushion is cushy. The Sunbrella cushions that came with our chairs 12 years ago have lasted beautifully and still look good. We got these new ones, so that we could move the old ones to a different set of chairs.
