Functional fibre TENCEL™ Lyocell

This mattress protector provides effective moisture management thanks to a terry surface made from 100% TENCEL™ Lyocell. Lyocell is a natural cellulose fibre that effectively absorbs moisture, stores it and lets it evaporate into the air during the day.


Natural hygiene & freshness

Thanks to the natural absorbent properties of Lyocell, our Bella Donna Clima mattress protector ensures a pleasantly dry and healthy environment that discourages dust mites, bacteria and unpleasant odours..

Sustainable TENCEL™ Lyocell

TENCEL™ Lyocell is derived from wood, a sustainable raw material that is fully biodegradable. The wood originates exclusively from sustainable, certified and controlled forestry management that follows the stringent guidelines of the Lenzing Wood and Pulp Policy.

TENCEL™ Lyocell  fibres have gained a good reputation for their environmentally sound, closed-loop production process, which transforms wood pulp into cellulose fibres with high resource efficiency and low ecological impact. The solvent-spinning process recycles process water and reuses the solvent at a recovery rate of over 99%.

As they are derived from nature, all standard TENCEL™ Lyocell fibre types are certified as biodegradable and are compostable under industrial, home, soil and marine conditions, so can revert fully back to nature.

For every bed

A solution for ALL mattresses – as if

  • Bed types

    Our mattress protectors provide a perfect, wrinkle-free fit on all mattresses. Also on boxspring beds, futon mattresses and waterbeds.

  • Mattress thickness

    We have three protector versions depending on the thickness of your mattress:

    • Standard protectors fit mattresses up to 30 cm thick
    • La Piccola protectors are suitable for toppers up to 12 cm thick
    • Alto protectors are designed for thicknesses of up to 45 cm (e.g. boxspring)
  • More sophisticated beds

    More complicated bed systems with:

    • An adjustable head section require our Duo1 version
    • Height-adjustable head and foot sections require our Duo2 version
    • A unique character require a custom-made sheet. Please ask your specialist retailer for advice.

Our combi sizes

We work with combi sizes: One sheet size will fit a range of mattresses. This is a practical side effect of our fitted sheets’ tremendous elasticity.

For example, Bella Donna Clima in a size 13 will fit mattresses with a:

Width of 140 - 160 cm
Length of 200 - 220 cm
Thickness of up to 30 cm

TIP: To ensure your mattress protector fits perfectly, please do not use the upper limits of all three measurements (width, length and thickness) in combination. In this case, the measurements 160 x 220 x 30 cm (WxLxT).

If you’re reaching the upper limits of all three measurements, we recommend choosing the next size up or opting for our Alto version. One of our specialist retailers will be happy to help you with this somewhat tricky question.

Fitted sheet format

All Formesse mattress protectors have the same format as a fitted sheet. In other words they envelop the mattress and are held in place by a robust elasticated border that is tucked away under the mattress. So unlike conventional mattress protectors, unattractive edges are not visible through the fitted sheet. Instead you have a beautifully smooth and even sleeping surface.      

No visible edges on your bed surface.

Easy to fit – which corner goes where

Especially when it comes to larger mattress protectors with a width of 160 cm or more, you’re often faced with the problem: "Which is the longer side and which is the shorter side?"
Every one of our protective covers comes with a care label, which also shows the size. The ‘clever corner’ with the label is designed to fit over the top right or bottom left corner of the mattress.

With the clever corner – your mattress protector fits perfectly first time.       

ClimatePartner certification – our contribution to climate protection

Since 2019 we have been working with ClimatePartner AG and supporting climate protection projects worldwide. In response to understandable public criticism of the lack of standardised guidelines around  green claims and the resulting risk of greenwashing, ClimatePartner AG has come up with a new label – one that is transparent, far-reaching and guided by binding reduction targets.  We have been using this new assessment process since 2023: We have completed the 5 steps for successful climate protection in cooperation with ClimatePartner and have received ClimatePartner certification for our company and our products.


High-quality, long-lasting bedroom textiles – that’s what the Formesse brand is all about. We see our company philosophy confirmed in the SLOW movement: We support a more appreciative, decelerated consumption of high-quality products with a much longer lifespan. In other words: We make the opposite of fast fashion, which prioritises offering the latest, constantly changing fashion trends in mostly poor quality and at the lowest possible price. 

We offer you premium quality – Made in Germany – that stands the test of time. SLOW.

Finest materials, naturally tested and certified

Cotton is a wonderful raw material, but unfortunately it doesn’t grow in Germany. We source our cotton and Tencel yarns and our super-fine elastane thread from selected German yarn dealers. The yarn we purchase is then knitted to form our jersey fabrics, dyed and finished in Germany. Around 95% of our products are made in Germany. A small but vital part is also carried out by a family business in Poland.

Our products are tested for harmful substances and certified by OEKO-TEX® Service GmbH.   

Certified according to OEKO-TEX® STANDARD 100, 97.0.7666, Institut Hohenstein

Washing tip

Our protective covers should be washed before first use. Not only is it more hygienic, it also creates our perfect fit, as all knitted fabrics shrink the very first time they’re washed. The degree of initial shrinkage has been carefully calculated in all our patterns.

Your easy-care protective cover should be washed regularly as this guarantees permanent hygienic protection for your mattress.
