Add supportive comfort to your everyday seating with the Cheer Collection Memory Foam Lumbar Support Pillow, shaped to follow the natural curves of the back while providing a cushioned surface for longer periods of sitting. The contoured memory foam core gently adapts to your body, while the versatile design can be positioned lower for lumbar and mid back support or higher for upper back comfort depending on your seating needs. Two adjustable buckle straps help keep the pillow securely positioned on most car, SUV, truck, office, home, and gaming chairs, making it easy to move from the commute to the workspace. A stretchy jersey knit cover made from 75% nylon and 25% spandex offers a smooth, breathable feel, while the built in zipper allows the cover to be removed and machine washed for convenient care. Measuring approximately 20 inches high by 16.9 inches wide, this portable back support pillow delivers broad coverage in a practical size for driving, desk work, travel, and everyday seated comfort
