Product description Package content: 1 piece waist headrest 1. Sitting all day at work, in the car and at home puts a huge strain on your back ... but it doesn't have to be anymore! Mount our lumbar support pillow on any chair or car seat for immediate and ergonomically correct positioning and posture correction. 2. Flat support cushions offer slight relief, but cannot provide support where it is needed most - on the lower back. The D-shape of our lumbar support adapts to the natural curvature of your lumbar spine, relieves the strain and helps you sit correctly. 3. You can certainly tuck a regular pillow behind your back and then spend the whole day constantly realigning, folding, repositioning and picking up the pillow when you get up. On the other hand, you attach our lumbar cushion once, that's it. 4. Most memory foam pillows are known for their heat storage - and thus promote sweat production. Our back support has a breathable cushion cover that allows gentle air circulation, intelligently dissipates body heat and keeps your back comfortably dry and relaxed throughout the day. 5. Best Back Support Pillow & Gifts This high quality ergonomic lumbar support pillow is a perfect gift for parents, office staff, teachers, drivers, students who sit for a long time. Perfect size for office workers, pregnant women, drivers and students to improve their posture.
