This lounge cushion is well suited for balancing exercises or relaxing. The lounger is filled with many small foam beads that adapt perfectly to the body. Nothing pushes or bothers you and is ideal for a peaceful rest or relaxation time. As you walk over, you have to rebalance with each step - promoting sensorimotor function, coordination and stability. This decor piece is a great cushion for floors in recreational places, for reading books, listening to music or studying and is more comfortable than a rug or mat. Perfect for early learning centers, classroom lounge areas or children's libraries where stories can be listened to. Filled with styrofoam balls. The Trevia CS polyester fabric cover with a zipper is removable and washable at 86°F.
