The upholsteries of Quersus chairs should be cleaned carefully with non agressive products.

Ultrasoft Hybrid Leatherette : Begin by vacuuming the leather to clear away loose dirt using a soft brush attachment to prevent scratches. For a deeper clean, use a slightly damp cloth to wipe down the leather. After cleaning, ensure the chair is left to air dry thoroughly.

Soft Woven Fiber : For loose particles or dirt, utilize a fabric vacuum. If there are any spills, promptly blot them with a dry cloth or paper towel. Refrain from rubbing the stain directly on the fabric and avoid using hot water as it can fix the stain.

Nano Fabric Suede : Use a dry microfiber cloth to wipe against the grain of the suede.
