1. Excellent elasticity, softness, elongation and compressive strength; good chemical stability, resistance to many solvents and oils; excellent wear resistance; excellent processability, thermal insulation, Adhesive properties, etc., is a cushioning material with excellent performance. 2. Its design improves the between the buttocks and the seat cushion, and makes a special double hole at the seat bone to make the area a larger annular area.
