The Concrete Seat is the innovative new lightweight seating range released by Fatboy. With its no-nonsense shape and size the Concrete Seat has multiple purposes. By unscrewing a cap on the bottom of the seat, it can be filled with sand or water to add some weight for extra stability and sturdiness. Available in five shades, the seat can also be topped with a choice of pillow from the range of 16 different designs. A practical asset to any interior and exterior, the stools can be combined to create a bench.
