Tru Flat Sheet

The Tru Flat Sheet is 100% cotton, woven in a percale (plain 1-over-1) structure at a true 400 thread count. That number is genuine: percale's construction makes it physically impossible to inflate thread counts the way multi-ply yarns can in other weave types. MATTEO used a very fine 100 singles cotton yarn to reach this count, which produces a sheet with a light, soft crispness rather than the heavy feel common in high-thread-count sateen.

Thread count in a percale is a direct measure of threads per square inch in a plain weave; there is a physical ceiling on how many threads fit. Many sheets advertised at 600, 800, or 1000 thread count use multi-ply or twisted yarns to reach those figures, which does not translate to a finer hand. The Tru Flat Sheet's 400 thread count is a verifiable single-ply count, resulting in a crisper, cooler sleeping surface than inflated-count alternatives. For a deeper explanation, see MATTEO's percale collection.

Percale's plain weave is one of the most breathable cotton constructions available, and the Tru Flat Sheet's 100 singles yarn keeps the fabric lightweight. The result is a sheet that releases heat rather than trapping it, which makes it well-suited to warm climates and hot sleepers. The garment-wash finish also relaxes the weave slightly, adding to its airflow without sacrificing the characteristic crispness percale is known for.

The Tru Flat Sheet is available in King (118 x 111 inches), Queen (100 x 111 inches), and Twin (79 x 106 inches). MATTEO recommends sizing up: use the King flat sheet on a Cal King bed and the Queen flat sheet on a Full bed. This accounts for the extra tuck-in depth those mattress configurations require.

The Tru Flat Sheet is garment-washed and dyed using non-toxic dyes, which is MATTEO's standard across all garment-dyed cotton bedding. The reactive dyes bond deeply to the fiber during the dyeing process, so there is no surface coating that can irritate skin. Because these dyes are not resistant to chlorine bleach or whitening agents like alpha hydroxy acids and benzoyl peroxide, MATTEO recommends keeping those products away from garment-dyed colors to preserve both the color and the fabric integrity.

Separate lights and darks before washing, and avoid overloading the machine, which can stress the long cotton fibers. Wash on a lukewarm cycle with gentle detergent and a cool rinse, then tumble dry on low heat, removing promptly to limit wrinkling. Line drying gives the best result. Bleach is safe on white cotton only; all garment-dyed colors should stay away from chlorine bleach and whitening agents. If pressing is needed, do so while slightly damp on the Lightweight Cotton or Medium iron setting.

Every Tru Flat Sheet is finished with a minimal 1/4-inch hem for a clean, low-profile edge. Darker colorways, including Coal, Fig, Night, and Bark, add a contrasting white top-stitch detail that makes the hem a deliberate design element rather than just a functional finish. The garment-wash process gives all colors a relaxed hand from the first use.

Yes. The Tru Flat Sheet is sold individually and also as part of the Tru Sheet Set, which includes the flat sheet, fitted sheet, and pillowcases in one coordinated purchase. Both options are available across the full color range, from neutral White, Off White, and Greige to deeper tones like Coal, Fig, and Night. The Tru collection is also available in the percale collection alongside other MATTEO cotton percale offerings.
