Vey disappointing. They are thin and flimsy and provide very little cushion. I’m not a heavy man and weigh 185 pounds and can feel the metal chair digging into me. Sunbrella makes these and they are not close to the same quality as their other products. Material, color and cut to size are all good but thinness makes these worthless.  Maybe if you’re the size of a jockey they’ll provide adequate cushion.
