The G-seat Ultra is an ergonomic gel seat cushion that effectively relieves pressure and improves your level of comfort when sitting for long periods of time. Designed for individuals who may be seated in excess of 12 hours a day, this unique gel pad is constructed from a premium visco-elastic gel and features a center relieved groove that address the point of contact. This helps eliminate soft tissue pressure and suspends the tailbone (coccyx), which eliminates direct pressure on the spine.
