I really like this set. They are very comfortable position and cushion wise. The little attached pillow is a pleasant addition. The cushions are water resistant but not waterproof meaning that a splash from the pool, sprinklelight quick rainfall will bead up and can be brushed off. A heavy downpour will soak them though. I didn’t get a chance to see how long it would take them to dry after their first thunderstorm as it was eveningbed time but they were dry when I checked the next morning. 
When folded they are still hefty to carry. If you’re trying to take them to a beach be prepared to have sore arms if you have to carry them any distance. To me that’s a good sign of sturdiness and I have no doubt they will last. The only thing I would like to see is some better edge protection for the foot end of the chair. Repeated dragging around concrete seems like it will wear them out pretty fast.
