Sometimes it doesn't take a lot to make a massive difference to an aching, painful back. A small adjustment to your posture, maybe, or a good stretch - or a clever seat cushion like this. Made from high-density foam with a soft polyester cover, it has a subtle tear-drop shape anatomically designed to provide optimum support for the back. Designed to fit most upright chairs (including car seats) the cushion is a perfect support for the lower lumbar region. Move it up the chair back and it does an equally good job on the upper back or even the neck - simply position it where you need it most. - mysmartbuy Black Adjustable Back Lumbar Supporting Chair Cushion with Machine Washable Cover - Measures H16 x W50 x D5.5cm
