By closely following the lines of the body from the thighs to the lower back, it distributes pressure over a wide area. The design that lifts the rear firmly supports the buttocks and provides a comfortable sitting experience. 2. 【5-6 seconds slow return, gently distributes pressure】The high-density low-resilience material slowly sinks in over 5-6 seconds after sitting, gently receiving the weight. This "slow return" characteristic softens the impact on the ischial bones and distributes body pressure over the entire surface without concentrating it on one point. It provides firm support without putting a strain on the body. 3. 【Non-slip stability and easy cleaning to maintain cleanliness】The bottom is coated with strong non-slip particles. The synergistic effect with the large and thick seat surface makes it difficult to slip even when standing up or changing posture, providing a stable support feel. Furthermore, the surface cover is removable and can be washed in a washing machine, so you can easily maintain a clean condition at any time. 4. 【Durable and resistant to deformation with high-density material】Because it uses high-quality high-density memory foam, it maintains softness and elasticity even after long-term use, and is designed to be resistant to sagging and deformation. It maintains a "presence" of substantial size and thickness. 5. 【Optimal fit regardless of the season with temperature-sensitive material】The high-density memory foam used in this product has a "temperature-sensitive" characteristic. In a low-temperature environment, the material may temporarily harden, but this is a natural property of the material. As you use it, when it reaches the appropriate temperature (about 20-30°C) with body temperature or room temperature, the molecules activate, creating the original "moderate support feel" and a unique support feel that fits the body. It provides the best sitting comfort in both summer and winter. 380
