These are very comfy. I love them on my new lounge chairs. Also from Wayfair. 
Sunbrella material is the best. Worth the extra money for sure. I purchased 2 for $100.00 at Canadian Tire last summer and they are squished and one is tearing already. 
I have purchased many items from Wayfair over the last year and I love them. Always telling my friends to shop with them.
