Cushion for Sitting for long hours

1. to correct the posture

2. to disperse the body weight

3. to ventilate well.

The EX was developed taking long-hour sitting seriously into consideration. Especially, the cushion was created: 1. to correct the posture, 2. to disperse the body weight, and 3. to ventilate well.

2. Disperses the body weight

This high-grade 2-layer structure with urethane makes low bouncing-back possible. and absorbs shock and vibrations well. Also, its 2-layer structure disperses the body weight evenly to your whole rear and substantially reduces the burden to your back. Furthermore, it holds your back in the stabilized position.

3. Well ventilated

The only drawback of the low bouncing-back urethane was the poor ventilation; however, this 3-dimensional honeycomb structure made this cushion possible to control heat and humidity. Thus, you feel cool in the summer and warm in the winter. Although this high-grade 2-layer structure with low bouncing-back urethane reacts to the temperature, it gives you comfortable touch throughout the seasons. This material is used by leading car companies as well.
