About this colour: Sky Blue

Sky Blue is a soft, dreamy pastel that brings the feeling of a clear summer sky into your bedroom. It's gentle on the eyes, refreshing and timelessly elegant. This colour works beautifully in both children's rooms and adult bedrooms, especially when combined with white, cream or warm wood tones.

Why a topper-specific fitted sheet?

Toppers are typically only 5–10 cm thick. A regular fitted sheet has too much fabric and ends up bunching, slipping or sliding off. Our topper fitted sheet has a tailored 10 cm pocket and fitted elastic all around, so it grips the topper precisely — no morning rumples, no slipping, no fuss. If your mattress is thicker than 10 cm without a topper, choose our standard fitted sheet with a 30 cm pocket instead.

What does 400 TC mean?

TC stands for "Thread Count" — the number of threads woven into one square inch of fabric. Our Premium bamboo bedding has 400 TC, with 200 horizontal and 200 vertical threads per cm². Because bamboo fibres are finer and stronger than cotton, 400 TC bamboo gives you the same dense, silky feel as 1,200 TC cotton — without the heavy weight. The result is a fabric that drapes beautifully, feels cool to the touch and only gets softer with every wash.

Match your topper sheet with...

• Sky Blue bamboo duvet cover
• Sky Blue bamboo pillowcases
• Sky Blue standard fitted sheet (for the mattress underneath)

Made consciously

Bamboo is one of the most sustainable fibres on the planet. It grows up to a metre per day without pesticides, fertilisers or irrigation, and produces 35% more oxygen than the same area of trees. Our bamboo is grown organically and processed under strict ECOCERT and OEKO-TEX® standards, so what feels good against your skin is also kind to the planet.

Care instructions

Wash at 30°C with similar colours. Don’t use fabric softener — it coats the natural bamboo fibre and reduces breathability. Tumble dry on low or line dry. Iron on a low setting if desired. Bamboo gets softer with every wash, so the longer you sleep on it, the better it feels.

Frequently asked questions

Will this work on my regular mattress?

It will only fit a topper or a thin mattress — the pocket is just 10 cm. For a regular mattress (up to 30 cm) choose our standard fitted sheet.

Will it work on memory foam toppers?

Yes — the elastic all around grips memory foam, gel, latex and pocket-spring toppers equally well, as long as the topper is 5–10 cm thick.

Will my bamboo bedding shrink?

A small shrinkage of 2–3% on the first wash is normal for natural fibres. Our sizes account for this, so your bedding will continue to fit perfectly.

Is bamboo bedding suitable for sensitive skin and allergies?

Yes. Bamboo is naturally hypoallergenic and antibacterial. The fibres are smoother than cotton and discourage dust mites — a great choice for sensitive skin, eczema or asthma.

How does bamboo bedding regulate temperature?

Bamboo fibres have a hollow micro-structure that wicks moisture away from your skin and allows air to circulate. The result: cool nights in summer, warm nights in winter, and fewer wake-ups from feeling clammy.

Are your products really 100% organic bamboo?

Yes — all our Premium bedding is made of 100% organic bamboo, certified by ECOCERT and Organic 100. No cotton blends, no polyester.
