The Feelfree Gravity kayak seat is unlike any other kayak seat on the market. This super comfortable, and super adjustable seat, will make all day fishing trips feel like you're sitting in your favorite chair. The Gravity Seat adjusts up to 10 inches high in 1 inch increments. The backrest is fully adjustable and even reclines. In the low position the seat sits almost flush on the deck of your kayak and is the perfect height for paddling. The high position is going to offer more visibility and will be more comfortable. There is a mesh side pocket for tackle or other storage. The Gravity Seat needs a wide footprint, 23 inches of deck space from side to side and 16 inches from front to back. It does not come with any mounting hardware.
