Product information

Triangle Support System®︎ (patent pending)
Supports three areas: the sacrum, the sitting bones and the thighs.
Gently holding the sacrum and sitting bones keeps the pelvis upright in an ideal seated posture, so sitting stays easy and tiring is less likely even over long hours.

An original three-dimensional structure keeps an ideal seated posture and disperses the pressure concentrated on the sitting bones
The seat-bone pockets are positioned so the pelvis sits where an ideal posture forms. Settling the sitting bones into the pockets prevents sliding forward, and the sacrum point supports from behind, guiding you into an ideal seated posture. Simply sitting keeps your posture correct with no effort, and using the cushion also showed a reduction in pelvic tilt angle.
Sitting without a cushion concentrates about 85% of the pressure on the sitting bones. With the Keeps cushion, pressure on the sitting bones drops to about 30%. Body pressure is spread across the whole contact surface, so you can sit comfortably for longer.
