Made from pure memory foam, giving you the support that current office chairs lack. With our office chair seat cushions, it supports your hips and reduces pain and fatigue in your lower back, hips and sciatic nerve. The bottom has non-slip rubber to stay in place even as you move around in the seat. Without worrying about it flattening out, the high quality memory foam of the seat cushion is slow to bounce back and returns to its original shape after every use. Our ergonomic “U” cutout that hangs your tailbone from a hard seating surface, relieving stress and improving posture.
