Sei Flat Sheet
Frequently Asked Questions
What fabric is the Sei Flat Sheet made from, and where is it manufactured?
The Sei Flat Sheet is 100% cotton in a sateen weave, woven at 600 thread count using 120/2 Ne yarn in both warp and weft for a balanced, silky hand. It is designed and manufactured by MATTEO in Los Angeles. Key specs at a glance:
- 100% cotton sateen weave
- 600 thread count, 120/2 Ne yarn construction
- Garment-washed for immediate softness
- Finished with a 1/2" double-stitch hem, contrasting white top stitch on darker colors
- Designed and manufactured by MATTEO in Los Angeles
- Hotel-grade weave density for a crisp, cool, silky sleep surface
Is the Sei Flat Sheet a good choice for hotel-quality bed sheets at home?
Yes. The Sei Flat Sheet is woven at 600 thread count with a balanced sateen construction, the same weave density used in high-end institutional bedding for its durability and smooth finish. The garment-wash process and double-stitch hem give it the crisp, polished surface associated with hotel-grade flat sheets, while the 120/2 Ne yarn keeps the hand soft rather than stiff.
Does a higher thread count always mean a better flat sheet?
Thread count measures weave density only; it does not account for yarn quality, fiber softness, or weave balance. MATTEO stopped at 600 thread count because counts above that typically produce a fabric that is stiff and lacks breathability. The Sei uses 120/2 Ne yarn in both warp and weft so the weave is dense and smooth without sacrificing drape.
What size Sei Flat Sheet fits a Cal King or Full bed?
MATTEO recommends the King flat sheet (118 x 111 inches) for Cal King beds and the Queen flat sheet (100 x 111 inches) for Full beds. Twin flat sheets measure 79 x 106 inches. You can pair the flat sheet with the Sei Fitted Sheet for a complete set in the same fabric.
