The GSeat ULTRA is ergonomically engineered to enhance comfort while seated. It slopes forward 5 degrees to return your pelvis to its proper posture, reducing low back strain and maintaining proper lumbar curvature. The GSeat ULTRA uses poly urethane gel to disperse pressure at the point of contact, while also featuring a center relieved groove that eliminates pressure on the tailbone and soft tissue. Dynamic Density Technology combines the benefits of gel and memory foam to create a lightweight cushion that provides superior comfort.
