Memory foam vibrating massage and heated seat cushion turns most chairs into a relaxing spot for cold days by adding vibration and warmth to your back and hips. The cushion uses resilient polyester memory foam with a soft plush cover to conform to your body and support pressure points while weighing only 3 lbs for easy handling. Six vibration motors work with optional lumbar and seat heating to help ease tense muscles. Five preprogrammed modes, four massage zones and three intensity levels are set using the remote.
