The best sitting position is to have your hips above your knees. Your office chair may have the option to tilt your seat downward at the front to create this position. If not, don't worry you may not need to get a new chair. The Harley Designer wedge will create that open hip angle for you on your current office chair.

This wedge is made of Memory Foam, making it comfortable, resilient and long lasting. It creates an 8 degree angle which is often enough of an angle for most people.

There is an option to have a coccyx cut out version. If you get coccyx pain (your tail bone) this option will relieve the pressure in this area. To ensure your sitting wedge doesn't slip on the seat make sure you purchase the wedge option with the fixing strap.

Dimensions: 36cm wide x 36cm deep x 8cm deep at the back.
