It is resistant to sagging even when placed on an office chair for long hours of desk work, and maintains an ideal posture. The honeycomb structure on the surface not only provides excellent breathability but also features an exquisite feel. As a cushion for chairs, we have paid attention to each material, achieving a comfortable sitting experience that prevents buttock pain, unlike conventional products. 2. 【Ergonomic Three-Dimensional Support Design】 This chair pad gently envelops the lower back and buttocks with a butterfly-shaped three-dimensional cut, distributing pressure over a wide area. It especially functions as a coccyx cushion, reducing the burden on the coccyx area. It is designed to be less tiring even when sitting for long periods. It naturally supports from the lower back to the thighs, making it effective for lower back pain relief. It transforms the seat of a hard chair into a custom-made fit. 3. 【Non-Slip and Easy-to-Clean Design】 This product has a strong non-slip treatment on the bottom to prevent slipping when standing up or changing posture. It stays firmly in place even on an office chair. Furthermore, the easily removable cover is machine washable, allowing you to maintain cleanliness. Combined with good breathability, it provides a hygienic and comfortable sitting experience that prevents buttock pain. 4. 【Durable and All-Season Compatible, Won't Lose Shape】 This cushion uses high-density memory foam, which is resistant to sagging and does not easily lose its shape, maintaining softness and elasticity even after long-term use. It is an all-season chair cushion that is cool and refreshing in the summer and maintains a moderate warmth that is not cold in the winter. Because it uses high-quality materials, there is no need to worry about it collapsing quickly like inexpensive products.
