Thank you for viewing our products from among many others. ★ Product Description 【Black Cushion】 Stylish black cushion. Can be used stylishly even without a cover. Uses high-quality black gel, and has excellent elasticity and comfort. 【Molds Designed from Ergonomics】 We have focused on a honeycomb structure to achieve maximum pressure distribution. With powerful pressure distribution, it won't break even if you sit on it with a cigarette or a raw egg. The cushion that prevents the egg from breaking is a hot topic. 【Doesn't tire even with long hours of sitting】 It's like weightlessness when you sit. Because you sit every day, we recommend a cushion that reduces the burden on your lower back and back. Just by placing one, the sitting comfort changes dramatically. The pressure distribution is so good that an egg won't break even if you step on it with your buttocks. This is a popular chair cushion that can also be used on the now-popular gaming chairs. We have received many happy comments saying, "My buttocks don't hurt anymore." This is a perfect gel cushion for those looking for a cushion for chairs that allows you to sit for long hours. 【Doesn't tire even with long hours of sitting】 It's like weightlessness when you sit.
