Fabric

When thread count became all the rage, we were disappointed with some of the gimmicks that were being used to declare absurdly high thread counts. Especially in percale fabrics. Thread count is simply a measurement of how many threads are in one square inch of fabric. A percale is a plain weave (or 1-over-1 structure) it is very challenging to weave a percale in very high thread counts; you can only pack so many threads into one square inch!

We love percale, so we decided to make the highest thread count percale possible using a very thin 100 singles cotton yarn. This is why we called it Tru(e). It is indeed a true 400 thread count percale with a light soft crispness that makes for a wonderful sleep.

Care Details

Wash

Wash should be separated into light & dark colors. Do not overload machine as this will damage long cotton fibers. We recommend a lukewarm wash cycle with a gentle detergent & a cool rinse.

Bleach may be used on white cotton bed linens only. Avoid using products that contain whitening agents such as chlorine bleach, alpha hydroxy acids and benzoyl peroxide on garment-dyed items. The reactive dyes used for garment-dyeing are not resistant to these whitening agents.

The largest challenge with garment-dyeing is the truth that it is an art, and not a science. We must allow for a shade variation of +/- 10% from dye-lot to dye-lot.

Drying

Tumble dry with low heat.Remove bed linens promptly from the machine to reduce wrinkling. For best results, line dry.

Ironing

We at MATTEO tend to prefer a lived-in look, as such, you don't find us ironing our sheets too frequently. If you prefer a crisp looking bed, our cotton bed linens should be pressed while slightly damp using the Lightweight Cotton or Medium setting.

Frequently asked questions

What is the thread count and weave of the Tru Flat Sheet?
The Tru Flat Sheet is 100% cotton in a percale weave with a true 400 thread count. Percale is a plain 1-over-1 weave structure, and weaving it at 400 thread count requires an exceptionally fine 100 singles cotton yarn. Most high-thread-count percale claims on the market rely on counting individual plies rather than individual threads; this sheet does not. The result is a light, soft crispness that holds up wash after wash.

How does 400 thread count percale compare to higher thread count sheets?
Thread count measures how many threads fit in one square inch of fabric. In a percale plain weave, there is a physical limit to how many threads can be packed into that space, which is why thread counts above 400 in percale typically involve counting individual yarn plies rather than distinct threads. The Tru Flat Sheet is woven from a 100 singles cotton yarn to reach a genuine 400 thread count, the realistic ceiling for this weave. The finish is clean and slightly crisp rather than heavy, which is what makes percale well-suited for year-round sleep.

Is the Tru Flat Sheet a good choice for hot sleepers?
Percale's 1-over-1 plain weave is inherently breathable because it produces a more open fabric structure than sateen. The Tru Flat Sheet's 100% cotton construction wicks moisture and allows airflow, making it a practical option for warm climates or anyone who sleeps warm. Its light, crisp hand stays cool against the skin without sacrificing the durability that comes with a 400 thread count cotton.

What size Tru Flat Sheet should I order for a Cal King or Full bed?
For a California King bed, order the King flat sheet, which measures 118 x 111 inches (300 x 282 cm). For a Full bed, order the Queen flat sheet, which measures 100 x 111 inches (254 x 282 cm). The Twin flat sheet measures 79 x 106 inches (201 x 269 cm) and fits a standard Twin.

What does garment-washed mean, and how does it affect the Tru Flat Sheet?
Garment-washing means the finished sheet is washed and processed after it is sewn, rather than the raw fabric being treated before cutting. This pre-softens the cotton so the sheet arrives with a broken-in feel from the first use. It also sets the color more evenly into the fabric. Because MATTEO uses reactive, non-toxic dyes in this process, garment-dyed colors do have a natural dye-lot variation of plus or minus 10%, which is characteristic of artisanal dyeing rather than a defect.

How should I wash and care for the Tru Flat Sheet?
Separate light and dark colors before washing, and avoid overloading the machine, as excess friction damages long cotton fibers. Wash on a lukewarm cycle with gentle detergent and a cool rinse. Tumble dry on low heat and remove promptly to minimize wrinkling; line drying gives the best result. Bleach is safe on white cotton only. On garment-dyed colors, avoid any products containing chlorine bleach, alpha hydroxy acids, or benzoyl peroxide, as these break down reactive dyes.

Does the Tru Flat Sheet work well as a hotel-quality bed sheet?
The Tru Flat Sheet is 100% cotton percale at 400 thread count, garment-washed for immediate softness and finished with a minimal 1/4-inch hem. These are the construction details that define hotel-grade bed linen: a durable plain weave, a high but honest thread count, and a clean finish that launders well over time. White and Off White colorways in particular replicate the crisp, neutral look standard in luxury hotel bedding.

Where is the Tru Flat Sheet designed and made?
The Tru Flat Sheet is designed and manufactured by MATTEO in Los Angeles. The fabric is woven using a fine 100 singles cotton yarn developed specifically to achieve a genuine 400 thread count in a percale structure, and every sheet is garment-washed and dyed with non-toxic dyes at MATTEO's studio. It is part of the broader Tru collection, which also includes fitted sheets, pillowcases, and sheet sets.
