This says it's made for larger adults, not so much! I'm about 280 and this simply did not work. I had to stay behind because of it. No matter how much air we put in it or how we (the guide and I) adjusted the seat, the ends came off the water and water came in because I went below the water line. I was sitting in several inches of water. Sitting low like that makes an uncomfortable seat an unbearable seating position. Simply put, ruined my day!
