When sourcing car upholstery, the price is primarily driven by material type and durability. Genuine Leather (Nappa or Top Grain) offers the highest luxury and resale value but comes at a premium. Synthetic Leather (PVC or PU) is more cost-effective and water-resistant. For high-performance needs, Microfiber Leather is a top-tier choice as it mimics genuine leather's breathability while offering superior abrasion resistance. Ensure the material thickness is at least 1.0mm to 1.2mm for durability, and verify the Martindale rub count (ideally >30,000) to ensure it can withstand daily wear.
