The bun is made of soft velour on the outside, with a moisture-resistant nylon inner liner and is filled with soft foam chunks. The bun can be used multiple ways for postural positioning. Weighted condiment bags, Ketchup and Mustard, are filled with a safe non toxic medium. The Ketchup and Mustard each weigh 10 pounds and can be used for additional proprioceptive feedback. The Ketchup and Mustard are surface clean only. A great addition for home, sensory room or classroom.
