Great for office or home, this cushion straps onto a chair and then provides various massages to various areas of the back while two large nodes knead the neck. Massaging and kneading are controlled separately--two speeds for each--by a control wand with a backlit LCD screen. The kneading nodes, which are covered by a stretch fabric, extend out 3-1/2 inches and are about the diameter of golf balls. They work in a circular motion, either clockwise (up and down), counterclockwise (down and up), or alternately, and firmly massage the neck muscles all the way down to the shoulders. For people of different heights, the nodes can be adjusted vertically by turning a knob atop the cushion.
Six massage motors--two each for the upper back, midback, and lumbar areas--deliver a "hammering" massage (like the sides of hands). In addition to high and low speeds, they can be set for two intensities, three modes (tap, stretch, pulse), and four directions. The tap mode is a single thump, the stretch provides multiple thumps that seem to stretch the muscles, and the pulse consists of rapid multiple thumps. Direction options are up and down, left and right, circulating, and automatic, which is a seemingly random pattern of varying speeds. A memory function recalls the favorite massage and kneading choices, and a timer offers settings up to 15 minutes. The cushion is covered in black simulated leather and measures 30 inches top to bottom, 20 inches wide, and 5 inches thick. It plugs directly into a wall socket and carries a five-year warranty against defects. --Fred Brack
