Knotty is a floor cushion with a plaited upholstery was designed by Kumeko, a design studio based in Prague, Czech Republic. Available in two sizes, the pouf was inspired by old weaving, knotting and basket-making techniques. Made from soft jersey tubes stuffed with highly resilient foam, and a lining that is filled with polystyrene balls, the cushion adjusts nicely and molds to your body making it extra comfortable.
