A sofa-style towable that seats three across a 56-in bench, this tube trades the cramped single-rider donut shape for a deck wide enough that friends ride together and still hold their own handles. The 900D nylon cover is the headline material: it is sun protective and colorfast, so a summer of direct exposure does not bleach the panels, and the precise stitching that joins them is what turns a seasonal toy into something that lasts several. Comfort is engineered rather than assumed. A backrest runs the length of the seat, an air-cushioned side wall softens the shoulder-to-shoulder contact through hard turns, soft EVA pads face the deck, and easy-to-grip handles sit within natural reach whether riders choose to sit or kneel. Dual towing points let the tube run either direction behind the boat, and the drainage pocket sheds the water that would otherwise pool and slow the ride. Load and speed limits are specific: a 661-lb capacity across 3 riders, 20 mph for adults and 15 mph for children, 1.2 PSI or 0.083 bar of working pressure, a 3 Bft wind ceiling and a 12-in maximum wave height, with a recommended minimum age of over 14 years old. The tow rope specification calls for 50-65 ft of line carrying a 3350-lb tensile rating. Inflated, the tube measures 76-in by 74.5-in by 32.5-in at a 35-lb net weight, deflates simply, and carries by its portable handle once packed, with repair patches included for the unexpected.
