It disperses the pressure from your weight, providing a stable sitting experience. Recommended for those who find cushions too soft and unstable, or too hard and causing their buttocks to hurt. ■ Thin yet with minimal bottoming-out feeling... This cushion can be used without significantly changing the height of your chair. Recommended for those who feel that thin cushions quickly make their buttocks touch the chair and feel hard. ■ Breathable cushion... The honeycomb structure gel reduces the contact surface with the body.
