Mulberry Silk Flat Sheets

Some beds are made around a flat sheet; others have never needed one. Ours are sold individually for the first kind of sleeper—and for anyone who wants one smooth mulberry silk layer without buying a set. Choose 19, 22 or 25 Momme, then check the finished dimensions against the tuck or drape you prefer.

A Flat Sheet Depends on How You Make the Bed

We do not think a flat sheet needs a rulebook. Some people tuck it tightly beneath the mattress and sleep between two neatly held layers. Others leave it loose because they like being able to move one light covering without moving the duvet. It can also be the single silk layer added to a bed that already has a fitted sheet you like.

That freedom is the reason we sell our mulberry silk flat sheets one at a time. You are not paying for pillowcases or a fitted sheet simply to get the piece you came for. Before choosing, picture how the sheet will be used on an ordinary night. The right size for a crisp hospital corner may not be the same size you would choose for a relaxed side drape.

Leave Room for the Tuck You Actually Want

A mattress size name does not tell us how much fabric you want hanging over the edge. Measure the mattress width and length, then add the drop needed on both sides. If the sheet will be tucked under the foot or sides, allow enough extra fabric to reach beneath the mattress without pulling every edge tight.

Compare that total with the finished measurements on the product page. A topper changes the height of the bed and can use up more of the drop than expected. If you are trying to cover the mattress itself rather than add a loose upper layer, an individual silk fitted sheet may make the bed easier to keep in place.

Three Weights, One Flexible Layer

Our flat sheets come in 19, 22 and 25 Momme. The 19 Momme version has the lightest hand and is easy to move around the bed. Twenty-two Momme adds a little more body. Twenty-five Momme gives the same simple rectangle a fuller fall and makes the fabric feel more present when you pull it across the mattress.

Momme measures fabric weight; it does not decide the correct size or the best way to sleep. A higher number is not automatically better for a person who prefers a lighter top layer. If you are still deciding which parts of the bed to replace, our broader mulberry silk sheets page places fitted, flat and baby options together.

The Layer Closest to You Should Feel Quiet

The value of a silk top sheet is not only how it looks when the bed is made. It is the large surface moving against the body through the night. Mulberry silk has a smooth hand that may create less dragging against skin and hair than a rougher fabric. Its breathability can also help the bed feel less stuffy when the room or other layers are warm.

A sheet cannot promise deeper sleep, clearer skin or healthier hair. What it can do is remove one source of coarse contact and give you a layer that moves easily when you turn. For many sleepers, that small physical difference is the reason a flat sheet earns its place on the bed.

Wash the Sheet Without Letting Its Size Work Against It

Large silk pieces need space. Follow the care label on the exact product. When machine washing is permitted, use cold water, minimal agitation, a neutral silk detergent and a roomy laundry bag. Do not crowd the drum with towels or clothing that can rub against the sheet.

Support the fabric as it dries instead of hanging all its wet weight from one corner. Keep it away from direct heat and strong sunlight. If a flat sheet is part of the everyday bed, a second piece in rotation gives the first one time to dry naturally. Our silk care guide covers the shared routine, while the product label remains the final instruction.

FAQs

Is a silk flat sheet the same as a fitted sheet?

No. A flat sheet is a rectangular piece without elastic corners. It can be tucked in or left loose. A fitted sheet wraps the mattress and uses elastic to stay in place.

Are THXSILK flat sheets sold as a set?

No. The products on this page are individual flat sheets. Pillowcases and fitted sheets are not included unless an individual product page explicitly says otherwise.

Should I use a flat sheet above or below me?

Most people use it above the body and beneath a duvet or comforter, but some use a flat sheet as a flexible mattress layer. Choose the arrangement that stays comfortable and manageable in your own bed.

Which Momme should I choose for a flat sheet?

Choose 19 Momme for the lightest hand among these three, 22 Momme for more body, or 25 Momme for a fuller drape. Size, preferred tuck and care routine matter alongside weight.

How do I know whether a flat sheet will have enough overhang?

Measure the mattress width, length and height, decide how much fabric you want on each side, then compare the total with the finished dimensions listed on the product page.
