The Benefits of TENCEL Lyocell: Cooler, Softer, Greener

A wood-based fibre made in a closed-loop process, absorbing moisture far more efficiently than cotton. What it is, how it compares, and why we weave ours in percale.

Short answer: TENCEL™ Lyocell is a wood-based fibre made in a closed-loop process that recovers over 99% of its water and solvents, and it absorbs moisture roughly 50% more efficiently than cotton, which is why it sleeps cooler. We weave ours in a percale weave for a soft, matte finish that stays cool through the night.

What TENCEL™ Lyocell actually is

Lyocell is a semi-synthetic fibre made from dissolved wood pulp, most commonly eucalyptus. TENCEL™ is the best-known lyocell brand, produced by the Austrian company Lenzing. The process is a closed-loop solvent spinning method that recovers and reuses over 99% of the solvent, making it one of the more environmentally responsible textile processes available. What comes out the other end is naturally smooth, breathable and moisture-wicking, exactly what you want from bedding that needs to stay cool and comfortable through the night.

How it compares to viscose and bamboo

All three are plant-based fibres, and the real difference is in how they're made.

TENCEL™ Lyocell. Closed-loop, recycling roughly 99% of the water and solvents used.
Viscose. Also wood pulp, but a more chemical-intensive and wasteful process.
Bamboo. Often chemically intensive too, unless specifically closed-loop or OEKO-TEX certified, in which case quality and impact both vary widely.

In short, TENCEL™ Lyocell is closer to a smarter, greener evolution of viscose than a separate category of its own.

Is lyocell better than cotton for bedding?

For a lot of sleepers, yes. Lyocell absorbs moisture around 50% more efficiently than cotton, pulling sweat away from your body and releasing it into the air faster. It's also smoother at the fibre level, which reduces friction against skin and hair, and it naturally resists bacterial growth, so it stays fresher between washes. The trade-off is price: lyocell bedding typically costs more than standard cotton, though it competes directly with long-staple and Egyptian cotton on softness and durability while using meaningfully fewer resources to produce.

The benefits, plainly

Super soft. Silky to the touch, softer than most cotton or bamboo.
Naturally cooling. Wicks moisture away and lets your skin breathe.
Sustainable production. Low water use and a closed-loop process.
Hypoallergenic. A good choice for sensitive skin.
Biodegradable. Fully compostable under the right conditions.

It suits you if you tend to sleep warm, want soft bedding without giving up on sustainability, or prefer a low-maintenance fabric that resists wrinkling on its own.

What makes ours specific

Ours is woven in a percale weave, one thread over, one under, which normally reads crisp and a little matte. Combined with TENCEL™'s own softness, the result is something unusual: percale's cool, breathable structure with a hand-feel that's soft rather than crisp. The pillowcases close with a hotel wing fold rather than a plain envelope back, a small detail that gives a cleaner, more tailored look.

"We wanted to create bedding that feels like a fresh hotel sheet, but made better," says Mathilda, Juniper's founder. "TENCEL™ Lyocell gave us the softness, and the weave gave us the structure."

Percale versus sateen, briefly

Percale is the tight, even weave behind most high-end bedding: cooler, lighter, matte, and more breathable on a warm night. If you'd rather have something warmer and silkier, sateen floats the thread over several layers instead of one, which gives it a smooth, lustrous surface, a warmer feel, and a more luxurious weight. Neither is objectively better; they're suited to different sleepers.

Questions answered

What is TENCEL Lyocell?

A semi-synthetic fibre made from dissolved wood pulp, most commonly eucalyptus, produced in a closed-loop process that recovers over 99% of the water and solvents used. TENCEL is the best-known lyocell brand, made by the Austrian company Lenzing. The result is naturally smooth, breathable and moisture-wicking.

Is lyocell better than cotton for bedding?

For many sleepers, yes. Lyocell absorbs moisture around 50% more efficiently than cotton, is smoother at the fibre level so it creates less friction against skin and hair, and naturally resists bacterial growth. It typically costs more than standard cotton, but competes directly with long-staple and Egyptian cotton on softness and durability.

Does lyocell shrink or stretch?

It can shrink slightly at high wash temperatures, so wash at 40 to 60°C and tumble dry on low heat or line dry to avoid it. It doesn't stretch: lyocell has no elastic properties, though some lyocell blends containing elastane will, from the elastane rather than the lyocell itself.

What's the difference between TENCEL Lyocell, viscose and bamboo?

All three are plant-based fibres, but the production process differs. TENCEL Lyocell is closed-loop, recycling around 99% of its water and solvents. Viscose uses stronger chemicals in a more wasteful process. Bamboo fabric is often chemically intensive too, unless it's specifically closed-loop or OEKO-TEX certified, in which case quality varies by producer.
