Our Natural Rubber Massage Peanut is ergonomically shaped for massaging muscles prone to tension along either side of the spine. Lean into a wall, office chair, or floor to target areas that need it most. The Natural Rubber Massage Peanut offers medium to firm pressure, relieving tight uncomfortable muscles and helping to improve circulation. Try lying on your back and placing the peanut between the floor and the base of the skull or back of the neck, this can relieve tension in the neck and head while also alleviating headaches.
