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 Lmell excellent performance. . The microporous bubble structure of the number of polyurethane materials absorbs energy and buffers. It is equivalent to a spring buffer with Lmell multi-balloon damping in the hand impact process. It has good impact resistance and compression resistance. It has no noise and no spark during the buffering process. Explosion-proof, safe, reliable and stable. . Has good heat dissipation and breathability. Allows you to sit on top of it and maintain a cool work and driving environment . Supporting power, almost comparable. It also provides just the right support based on the full release of the vertical pressure of the human body caused by sedentary . Its design improves the contact between the buttocks and the seat cushion, and makes a special double hole at the seat bone to make the contact area a larger annular area. According to the physics principle, when the area of the seat cushion and the buttocks is larger, The pressure on the buttocks is smaller. . Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
