I think these will work OK. I worry a bit about the quality of fabric and time will tell. It doesn't feel as thick as other Sunbrella fabrics I have but they fit pretty well on our existing chairs. They wrinkles should relax over time. The cushions feel comfortable.

I have a hanging chair that the cushion that came with it just wasn't full enough to not feel the structure of the chair. It was so hard to find something in a nearly equal color, but, having three cushions (and extra one for the head/neck area) and not just bottom and back. Wayfair, as always comes through! This came in a relatively small bag, not a box, which was surprising, as the cushion was vacuum packed to decrease size. I would have thought the danger of a puncture would be too high. But it arrived without issue, with many layers of outside plastic wrapping and a lot of packing tape (you really can't see it in the photos) and then inside was the vacuum packed guide. I would definitely recommend being very careful with a knife or scissors when trying to open it. But, once open, and laid out for a while it expanded into full sized cushions. Fit perfectly in my chair (not pictured). It has a nice texture in the fabric as well, making it feel like a very high quality item. I would absolutely recommend this cushion if you are looking for a higher backed replacement!

This outdoor cushion set is amazing! The seat cushion has a nice and dense pad, and the back head rest is filled with a pillow like filling material. It’s very comfortable at 24.5” X 27” is oversized for a regular patio chair, so my husband built me a chair!

The comfort sunbrella high back chair cushion is fabulous!!! The cushion is super thick and cushy and feels amazing to sit on. This is by far thicker than any other cushion I have purchased in the past. It is so comfortable to sit on and the waterproof fabric is excellent. I highly recommend this cushion.

Cushions are fantastic. They are not for the standard Adirondack however. They are huge and going to be a pain to return
