Organic Cotton Sateen Fitted Sheet

The Organic Cotton Sateen Fitted Sheet is 100% Egyptian cotton, woven at 300 thread count in a sateen weave and garment-washed in MATTEO's Los Angeles dye-house. The sateen construction gives the face of the fabric a smooth, silky feel, while the garment-washing process produces softness from the first use. The cotton grows softer with every wash rather than stiffening over time.

The fitted sheet has 16-inch pockets that fit mattresses up to 20 inches deep comfortably. The elastic band spans the entire perimeter of the sheet and is encased in a high-density stitch at the bottom seam, so it holds its grip through repeated washing and years of use. Corner construction uses a flat felled seam tacked at the top corner to reinforce the areas that take the most wear.

The fitted sheet is available in Twin (39 x 75 x 16 in.), Twin XL, Full (54 x 75 x 16 in.), Queen (60 x 80 x 16 in.), King (78 x 80 x 16 in.), and Cal-King (72 x 84 x 16 in.). All sizes share the same 16-inch pocket depth. If you are between standard sizes or have a non-standard mattress, the 16-inch pocket provides enough depth to accommodate most specialty mattress configurations up to 20 inches.

Wash in lukewarm water with a gentle detergent and a cool rinse, separating light and dark colors. Do not overload the machine, as that puts stress on the long cotton fibers. Tumble dry on low heat and remove promptly to reduce wrinkling; line drying gives the best results. Avoid chlorine bleach, alpha hydroxy acids, and benzoyl peroxide on garment-dyed colorways, as the reactive dyes are not resistant to whitening agents.

MATTEO developed this fabric specifically to eliminate the need for ironing. The garment-washing process gives the sheet a lived-in softness that reads well without pressing. If you prefer a crisper look, press the sheet while it is slightly damp on the Lightweight Cotton or Medium iron setting.

Thread count measures weave density, not overall quality. At 300 thread count, this sateen sheet uses 60s yarn count Egyptian cotton, which determines the fineness and smoothness of each individual fiber. A lower thread count woven from high-quality long-staple cotton will feel softer and last longer than a high thread count sheet made from shorter, coarser fibers. MATTEO's position is that thread count is one measurement among several: fiber length, yarn size, weave balance, and finishing process all contribute to how a sheet actually feels and wears.

MATTEO uses reactive dyes in its garment-dyeing process, applied in the brand's Los Angeles dye-house. The process does not use chlorine bleach or harsh whitening agents. Because garment-dyeing is done by hand in small batches, MATTEO allows for a natural shade variation of plus or minus 10% between dye lots, which is a normal characteristic of artisanal dyeing rather than a defect.

Sateen and percale are both 100% cotton weaves, but they have a different hand and finish. Sateen has a higher thread-over construction that produces a smooth, slightly lustrous face; percale uses a one-over-one-under weave that gives a matte, crisp finish. The Organic Cotton Sateen Fitted Sheet is garment-washed to soften the fabric before it reaches you, so it starts soft and continues to improve with use, while percale typically starts crisper and relaxes gradually. If you prefer a silkier feel, sateen is the better choice; if you want a cooler, more structured hand, MATTEO's luxury cotton percale sheets are worth comparing.
