ErgoForm - Pronounced Lumbar Support
The Ergoform seat back contains a comfortable, firm, pronounced lumbar support to ensure you're supported. It allows for the pelvis and hips to adjust to a corrected tilted position so you know when you are sitting with your back rested against the seat back for many hours a day, the spine is supported comfortably to relieve and help prevent back pain.
Ergo Air - Triple Band / Pneumatic Lumbar Pump
The pneumatic means you can precisely increase or decrease the amount of pressure in the lumbar support of your chair. Using the pump, you can increase the lumbar support to provide a more firm and pronounced lumbar support in the back rest or you can decrease the lumbar support to reduce the pressure of the lumbar support. This feature is ideal for anyone who experiences back pain when sitting at their desk or anyone who has recently undergone back surgery, as you will be able to adjust the lumbar support to specifically suit your personal preference.
