Three folding boat seats create a flexible seating layout on your deck, with two high-back chairs measuring 17.5 x 21 x 23 in and one low-back center chair to fit different positions. Each high-back seat folds down to a compact 17.5 x 17.5 x 10.5 in to free up deck space when not in use. PVC upholstery is sun-protective, wear-resistant, weatherproof and easy to wipe clean. High-density 28D sponge padding and curved backs follow the shape of your body to improve comfort and support up to 330 lbs per chair.
