From my Series of Tubes collection, one pillow that unties into three. There are many ways to connect the pillows, or use them separately. Need to elevate just one ankle? Tie it on! I like to knot all three together to form the ventricles of a heart. Set includes one yellow, blue and red tube, filled with 90% recycled polyester fibers. All fabric is 100% cotton. Tubes measure approximately five feet long.
