The Feel Seating System, by Animi Causa’s Sarit and Amit Axelrod, is 120 foam-filled spheres in stretch fabric, each tied on individually, that you push and pull into a sofa shape, a slouched lounger, or a flat bed-like surface. It has no frame or fixed form — the balls just hold whatever position you leave them in. Animi Causa’s site currently lists the Deluxe as out of stock, with a notify-me waitlist rather than an active order button.
