This is the compact lumbar support pillow that folds into a zippered pouch the size of your hand and expands to provide ergonomic support on the seat of your choice. Crafted from memory foam, it contours to the shape of the lower back to relieve aches and pain while sitting in an office chair, driving in the car, or flying. The moisture-wicking cover distributes heat to keep the skin dry and cool. Slips easily into a jacket pocket, handbag, or suitcase. Designed for most straight seat backs. Black pouch and midnight navy pillow. 9 3/4" H x 11 3/4" W x 4 3/4" D. (4 1/2" L x 7" W x 3" D packed).
