elastic breathable mesh with a threedimensional woven structure accelerates air circulation, effectively dissipates heat and moisture, and keeps the seat dry and comfortable even after long driving. It helps prevent the stuffy feeling common on hot summer days. Ergonomic design fits mainstream car seats. Edges have elastic bands and the bottom uses nonslip buckles to stay fixed in place, preventing displacement during driving and contributing to safer operation. Upgraded durable construction. Thickened Oxford cloth lining plus an elastic mesh layer provide antistretching, friction resistance, and strong loadbearing capacity. It is not easy to deform or collapse with longterm use. Tool installation and easy maintenance. Hook and strap design allows installation in about 30 seconds. The seat cushion can be washed by conventional methods to keep the car clean and fresh at any time, and should not be rinsed or machine washed. Compatibility and performance.
