Federa in Seta: the Complete Guide Before You Buy
Shop the Silk Pillowcase →Three Criteria to Check Before Any Purchase
Exact composition (100% mulberry silk, never a blend), weight expressed in momme (ideally between 19 and 25 for a good durability/price balance), and seam finishing — three objective elements that separate a quality federa in seta from a polyester imitation.
Why the Italian Market Often Confuses Silk and Satin
The term 'raso' (satin) refers to a weave, not a fiber — a satin weave can be made of polyester, cotton, or silk; only the explicit mention '100% seta' on the label guarantees the natural fiber sought for its specific benefits.
"'Raso' describes a weave, not a fiber — checking for the explicit 100% seta mention remains the only reliable way to know what's actually being bought.
