Up for over a month now, so far it’s great. Three air chambers plus the seat and head rest, holding up fine. Nice sturdy two-part valves so air doesn’t escape while you’re pumping. Not the typical pool toy type valves. You’ll need a pump with the correct adapter. Comfortable for 2-3 adults. Yes it will list to one side if your ground isn’t perfectly level, that’s how gravity works. Don’t overfill it. It’s big enough but not too big. Price varies wildly from day to day so maybe keep an eye on that before purchasing. Highly recommend overall.Tip: if your ground slopes slightly, position the bench side on the downhill side and it will slump less, as the air in the bench displaces some of the water. Eureka! ?
