Bambou vs coton pyjamas : quel tissu est meilleur pour le sommeil ?

Quick answer

For most sleepers, cotton is the safer everyday choice: it is durable, easy to wash and breathes well. Bamboo viscose wins when you want a silkier, cooler-feeling drape against the skin. If you sleep hot or want a more sustainable fibre story, bamboo viscose is worth it. If you want low-maintenance longevity, cotton is the practical pick. The right answer depends on how you sleep and how much care you will actually give the garment.

Bamboo and cotton pyjamas both promise comfort, but they behave very differently in bed. One feels cool and fluid; the other feels crisp and dependable. Neither is universally better — the right choice depends on your body temperature, your laundry habits and what you want the fabric to do after fifty washes.

This comparison looks at bamboo viscose and cotton on the factors that actually affect sleep: breathability, moisture handling, durability, care and eco claims. We use two real Homebodii sets — the Vienna Stripe Cotton Pyjama in Blue Stripe and the Aurora Lounge Pyjama Set in Black Floral, made from TENCEL™ — to show what each fibre feels like in practice.

How the two fabrics actually differ

Cotton is a natural plant fibre spun into yarn. It is breathable, absorbent and holds up to repeated washing, which is why it has been the default sleepwear fabric for generations. It feels crisp at first and softens over time. The trade-off is that cotton can feel heavier and holds moisture rather than releasing it quickly, so it may cling when you sweat.

Bamboo viscose is a regenerated cellulose fibre made from bamboo pulp. It drapes like silk, feels cool to the touch and wicks moisture away from the skin more readily than cotton. It is often marketed as eco friendly, but the chemical process used to turn bamboo into viscose matters — look for closed-loop or certified production if sustainability is your priority. It is also more delicate: it can pill and needs gentler washing.

• Cotton: crisp, durable, easy care, holds moisture
• Bamboo viscose: silky, cool, moisture-wicking, more delicate
• Both breathe, but bamboo viscose feels cooler against skin

Breathability and temperature regulation

If you sleep hot, bamboo viscose has the edge. Its smooth, low-friction surface and moisture-wicking behaviour help it feel cooler and less clingy than cotton. That makes it a strong choice for warm rooms, hot sleepers and anyone who wakes up damp. Cotton still breathes, but it can feel heavier and stay damp longer, which is why some sleepers find it less comfortable in summer.

For cool sleepers or year-round use, cotton is often the more versatile option. It insulates slightly better and feels substantial without being heavy. The Vienna Stripe Cotton Pyjama in Blue Stripe is a good example: 100% cotton, a long-sleeve button-up shirt and wide-leg pants with an elasticated waistband and drawstring tie. It is designed for softness from the first wear and gets softer with each wash.

• Hot sleeper? Bamboo viscose usually feels cooler
• Cold sleeper or year-round? Cotton is more adaptable
• Both are breathable — the difference is how they handle moisture

Durability and care

Cotton is the low-maintenance option. It tolerates regular machine washing, resists pilling and keeps its shape. The Vienna Stripe Cotton Pyjama is a straightforward example: 100% cotton, machine-friendly, and it softens rather than degrades with washing. If you want pyjamas you can throw in with the rest of your laundry, cotton is the safer bet.

Bamboo viscose needs more attention. It is softer and more prone to pilling, so wash it cold, inside out, and avoid harsh detergents or high heat. The Aurora Lounge Pyjama Set in Black Floral uses TENCEL™ fabric — a branded lyocell — which is known for being soft, breathable and kinder to the environment than conventional viscose. It still benefits from gentle care. Treat it well and it stays smooth; treat it like cotton and it will show wear faster.

• Cotton: machine wash, tumble dry low, long-lasting
• Bamboo viscose: cold wash, air dry, handle gently
• If you want zero-fuss care, choose cotton

Eco claims: what to check

Bamboo grows quickly and needs little water, which is why bamboo sleepwear is often marketed as eco friendly. But the viscose process can involve harsh chemicals unless it is closed-loop. If sustainability matters, look for TENCEL™, lyocell or OEKO-TEX Standard 100 certification. The Grace Lounge Pyjama Set in Rose Pink with Champagne is certified by OEKO-TEX Standard 100, which means it has been tested for harmful substances — a useful signal regardless of fibre.

Cotton has its own footprint: conventional cotton uses significant water and pesticides. Organic cotton is better, but it is not automatically more sustainable than a certified bamboo lyocell. The honest answer is that no fabric is perfect. Choose based on the certification on the label, not just the fibre name.

• Bamboo viscose is not automatically eco friendly
• Organic cotton is better than conventional, but certification matters more

Trade-offs at a glance

• Feel: Bamboo viscose feels cooler and silkier; cotton feels crisper and more substantial. Choose bamboo if you want a cool, fluid feel; choose cotton if you prefer a classic, structured hand.
• Moisture and breathability: Bamboo viscose wicks moisture and dries faster; cotton absorbs but can stay damp and cling. Hot sleepers and humid climates favour bamboo viscose; cool sleepers are fine with cotton.
• Durability and care: Cotton tolerates machine washing and resists pilling; bamboo viscose needs cold, gentle washing and air drying. If you want low-maintenance laundry, cotton is the practical choice.
• Eco credentials: Bamboo viscose is only as green as its processing; cotton's footprint depends on organic and certification status. Check for TENCEL™, lyocell or OEKO-TEX Standard 100 rather than trusting the fibre name alone.

Real pyjamas that show each fabric

• Vienna Stripe Cotton Pyjama – Blue Stripe: Crafted from 100% cotton with a long-sleeve button-up shirt and wide-leg pants featuring an elasticated waistband and adjustable drawstring tie. A pure cotton set that demonstrates the fibre's breathability and easy-care durability — ideal if you want low-maintenance sleepwear that softens with every wash.
• Aurora Lounge Pyjama Set Black Floral: Crafted from TENCEL™ fabric, described as luxuriously soft, breathable and kind to both skin and the environment, with a long-sleeve shirt with piping and buttons plus full-length pants.

• Grace Lounge Pyjama Set - Rose Pink with Champagne: Made from premium non-crush satin and certified by OEKO-TEX Standard 100. A useful reminder that certification — not just fibre type — is the clearest signal of a lower-impact, skin-friendly pyjama.

How to choose

Best for

• Hot sleepers who want a cooler, silkier feel against the skin
• Shoppers who prioritise a more sustainable fibre story and will care for delicates
• Warm climates or summer sleepwear

Not for

• Anyone who wants to machine wash and tumble dry without thinking
• Sleepers who prefer a crisper, more structured fabric
• Buyers who want the lowest-maintenance option

There is no single best fabric for sleepwear — only the best fabric for how you sleep and how you wash. Cotton is the durable, easy-care default; bamboo viscose is the cooler, silkier upgrade. Match the fibre to your body temperature and laundry habits, and you will sleep better for it.
