Rigid enough to float two adults. I've kept it inflated for over a month & not any noticeable air leakage so far. Material looks durable, dragging over beach sand does leave some scratches to the surface painting but the fabric seemed fine. Seats are attached to bottom of boat with loop n hook that's not as secure & may come loose easily especially for the back seat, however the reinforcement belt is a big plus as it effectively holds the seat in position. The valves for the seats are cheap ones that can go off too easily. The "drainage valve" located at rear of the boat is also toy-like and can't remain its opening position, that makes it awkward trying to expel the water through. Other than that it's a very nice kayak to have.
