This amazing sensory seating conforms to your body and provides sensory input like no other furniture can. Other typical bean bags flatten over a short period of time but the polystyrene micro beads filling this seating are so tiny that the seat stays plump for years to come. The nature of these micro beads allows you to dig your body into the stretchy fabric and squishy filling and feel surrounded by calming pressure. Each Yogibo seating product has a soft stretchy jersey cover that can be removed for washing. Extra covers are sold separately as well. Sink into a Yogibo today and let the relaxation begin!
