1.TEMPERATURE BALANCE - The three materials used in our lumbar support pillow work together to address back discomfort – all without causing more discomfort. Firm yet comfortable, the pillow's supportive memory foam gently guides your spine into the correct, pressure-relieving position. The memory foam won't flatten, retaining its shape no matter how long it's used. Meanwhile, the gel core is designed to keep your lower back from feeling too warm. Topping these comfortable cushions is a ventilated mesh layer, which encourages breathability during long periods of use. 2.ERGONOMIC DESIGN - 's Lumbar Support Pillow isn't like a standard chair cushion or a pillow you use to sleep. It's designed specifically to fit the curve of your lower back, naturally supporting your body as it's supposed to sit. This is done to relieve the pressure and strain off your lower back, especially while sitting in less-than-ideal positions like you would in a car or on an uncomfortable chair. 3.VERSATILE INSTALLATION - Sitting in comfort is at your control. 's back pillow can be used in most places where you may need extra lumbar support. Install quickly with the adjustable one-clip belt, generous enough to fit around many types of chairs. The lightweight and portable pillow can be easily moved from vehicle to vehicle, or even from room to room. Carry easily on airplanes or to and from work. It also fits in wheelchairs. 4.SUPPORTIVE - Our lumbar support pillow could help alleviate the pain and discomfort associated with lower back soreness, injury, chronic condition, or simply add a little more support for those who sit for long periods at work or drive hours-long distances. Its ergonomic design, high-grade memory foam and gel materials, and firm support are all designed to gently hold you in the correct position, alleviating pressure and stress on this sensitive area of the body.
