The adjustable feet have a large, soft rubber tip that is safe for any pool floor. How much do the Pool Stools weigh? The 24 inch model is 16lbs and the 30 inch model is 30lbs. Once placed in the water, they self-fill with water and weigh more. Once removed, they self-drain and return to original weights for easy transportation and storage. What are the recommended water depths for each pool stool? The small pool stool (20" tall) is recommended for 28" - 46" of water and our large pool stool (30" tall) is recommended for 36" - 53" of water. Do Pool Stools work for above ground pools? Absolutely! They do just as well in above ground pools where it can be even harder to permanently mount a poolside bar.
