The Ridgeback cushion
Designed for drivers and is also useful for working at a computer.
The cushion includes a strap at the top to attach to a car headrest and a side strap for office chairs.
Posture while driving is strained, because sitting down and holding our legs and arms forward is difficult. The Ridgeback cushion supports the upper back to improve the position of the neck and shoulders. It provides light support for the lower back to avoid lumbar hyperextension. Hypermobile joints can also benefit from the support of the cushion.
