Which fabric is best for a pillowcase?

Overview of pillowcase materials

This overview describes typical properties, not guarantees. Thickness, fibre mix, weave density, finish and any extra pillowcase can change the feel.

Material and weave are not the same

Cotton, polyester, silk and lyocell are fibre types. Satin and percale mainly describe how yarns are woven. A satin pillowcase can be made of silk, but also cotton or polyester. The word ‘satin’ alone does not indicate the fabric.

‘Bamboo’ also requires extra attention. For bamboo rayon, the official European fibre name is usually viscose. Bamboo refers to the plant source of the cellulose, not the final fibre name. Always check the full composition on the sewn-in label, not just the product name.

When is cotton the best choice?

Cotton is a logical all-round choice when you want a familiar sleep feel and easy care. The final touch varies by weave: percale usually feels firmer, while cotton satin can feel smoother.

The OnePillow hotelcover is made of 100% quality cotton and can be washed at up to 60 °C according to current product information. This cover suits sleepers who want to wash their pillowcase regularly at a higher temperature.

Cotton is ideal if you:

• seek a familiar and fresh feel;
• value easy washing;
• prefer a classic cover;
• do not need special cooling silk.

What does a bamboo mix mean for a pillowcase?

‘Bamboo’ on packaging does not always show the full composition. Bamboo rayon is usually labelled as viscose in Europe. Only if a different process is used can lyocell be the correct fibre name. Also check if the fabric is mixed with polyester or another fibre. The ratio and weave affect feel and care.

The OnePillow coolingcover with a warm and cooling side is described on the product page as a mix of bamboo and polyester fibres. OnePillow currently does not publish percentages. Therefore, we deliberately call it a mix and do not specify exact fibre ratios.

The coolingcover is mainly a practical choice if you get warm quickly, like switching between a cooler and warmer side, or prefer a soft contact surface. The cooling side is most noticeable on direct contact. A thick extra pillowcase can reduce this direct feel. For warm nights, also read the practical tips for a cooling pillowcase in summer.

How do silk, satin, lyocell and flannel differ?

These materials and finishes can be good alternatives, even though OnePillow does not offer them as its own cover.

• Silk: usually feels very smooth but requires more careful care and is often more expensive.
• Satin: is a weave. Always check if the fibre is cotton, polyester, silk or a mix.
• Lyocell: is a cellulose fibre often chosen for its supple feel and moisture comfort. TENCEL™ is a brand name from manufacturer Lenzing.
• Flannel: has a brushed surface and feels warmer, making it pleasant for cold nights.

For specific advice on skin problems, allergies or medical issues, consult a specialist. A material name alone is insufficient to predict such effects.

Which pillowcase suits your way of sleeping?

Don’t choose just by material name; start with your main need:

• You get warm quickly: choose a thin, well-fitting cover or one with a cooling side. Also consider room temperature and your other bedding.
• You want easy washing: check the maximum wash temperature and drying instructions. Cotton is often practical, but the care label is decisive.
• You are sensitive to texture: pay attention to weave and finish. Silk and satin usually feel smoother; percale and flannel have a more distinct surface.
• You want to change by season: use different covers or choose a double-sided cover.
• You seek support: first choose the right pillow height and filling. The cover mainly affects feel and sleep climate, not the pillow’s basic shape.

The right height is especially important for side sleepers. Also read how to adjust a pillow for side sleepers.

Which OnePillow cover suits you?

OnePillow combines three different layers around the same adjustable pillow:

• Hotelcover: 100% cotton, classic feel and washable up to 60 °C according to product information.
• Coolingcover: a mix of bamboo and polyester fibres with a warm and cooling side.
• Inner cover: the technical base layer around the filling, with a breathable structure and a foam layer inside so you feel the foam flakes less directly.

The inner cover is not intended as a separate pillowcase for direct contact with your face. Support mainly comes from the adjustable filling amount and chosen height. More about this in the explanation on choosing an adjustable pillow.

So: what is the best fabric for a pillowcase?

For practical convenience and washing, cotton is often the safest all-round choice. Those who get warm quickly may prefer a thin cover or a cooling side. Those seeking the smoothest surface look to silk or a satin weave. And those who get cold quickly may find flannel pleasant.

The material name is just the start. Also check the full fibre composition, weave, thickness and care label. Ultimately, the best pillowcase is the one that feels comfortable, suits your bed temperature and is easy enough to keep clean regularly.
