    Frequently Asked Questions

    What fabric and thread count is the Sei Sheet Set made from?

    The Sei Sheet Set is 100% cotton sateen woven at 600 thread count, MATTEO's highest thread count fabric. The sateen weave gives the face of the fabric a smooth, silky finish while maintaining the density and durability associated with hotel-grade bed sheets.

    Does the Sei Sheet Set deliver the kind of finish found in luxury hotel beds?

    Yes. At 600 TC, the Sei Sheet Set meets the density and weave specifications used in high-end hotel bedding. Key specs: 100% cotton, sateen weave, 600 thread count, garment-dyed using non-toxic dyes, designed and manufactured by MATTEO in Los Angeles. The sateen face produces a crisp, smooth surface with a hotel-style finish.

    How should I care for the Sei Sheet Set to keep the fabric in good condition?

    Machine wash in lukewarm water with a gentle detergent, using a cool rinse, and keep colors separated by light and dark. Tumble dry on low heat and remove promptly from the dryer; line drying gives the best results. Avoid bleach and any products containing chlorine or whitening agents, as these will affect the garment-dyed color.

    What sizes does the Sei Sheet Set come in, and what is included in each set?

    The Sei Sheet Set is available in Twin, Twin XL, Full, Queen, King, and Cal King. Each set includes one fitted sheet, one flat sheet, and either one or two pillowcases depending on size. Buying as a set saves 10% compared to purchasing each piece individually.
