The slow-rebound memory foam cushion is the preferred curved hip design for people who sit for a long time. The slow-rebound memory foam core allows your hips to always maintain an S-shaped curve. The sinking wrapping supports the hips on both sides to bear the force first when sitting down, giving the center of the hips a buffer space, fitting the hip curve, and shaping beautiful hips. The hollow ventilation and dehumidification can keep the air in the hips uniform and give the hips a refreshing and hygienic environment. It solves the problem of hot and humid air when people sit for a long time. It is ergonomically designed and adopts a special "hip design" to sink and wrap the hips to avoid hidden diseases such as hemorrhoids caused by poor blood circulation in the hips due to long-term sitting pressure. The correct sitting posture conforms to the ergonomic structure. The uniform support of the seat cushion on the hips can stop the back from stretching naturally and maintain the correct sitting posture. It effectively corrects the sitting posture of modern people.
