When sourcing high-end Savonnerie carpets, you must prioritize material composition and knot density. Authentic Savonnerie-style carpets should use 100% New Zealand wool or premium silk blends for the pile. The knot count (often measured in lines per inch) determines the detail of the floral and medallion patterns; for B2B luxury standards, a minimum of 90 to 120 lines is recommended. Additionally, verify the pile height, which typically ranges from 8mm to 12mm to provide the characteristic plush, velvet-like texture.
