The surface is soft to the touch and waterproof. The interior is filled with density memory foam, providing elasticity and support to effectively buffer vibration for a more comfortable ride. Breathable design and shock absorption: Ventilation slots in the middle of the seat surface ensure air flow between the seat and the rider, promoting ventilation and reducing stuffiness. The bottom includes shockabsorbing balls that flexibly respond to multidirectional impacts, enhancing overall shock absorption. Ergonomic design: The front end is relatively narrow to avoid restricting thigh movement and reduce friction. The rear end is widened, and a decompression groove is shaped to fit the perineal area, helping relieve pressure and prevent compression of sensitive parts.
