In brief

What makes this sheet different to Bella Donna Jersey?

As all of our products have exceptional properties, it’s not always easy to tell the difference just by looking. So how can you decide which fitted sheet suits your needs best? Let’s take a brief look at the differences between Bella Donna Premium and Bella Donna Jersey.           

A more exclusive knitted structure

As the name reveals, Bella Donna Premium shares many of the exceptional properties of our Bella Donna Jersey – it’s just even more exclusive. The sheet has an even denser and more uniform knitted structure, creating a particularly smooth and silky surface..  

A dreamlike feel – like velvet or silk.    

Mercerisation as a finishing process

Bella Donna Premium undergoes an additional, very elaborate finishing process called double mercerisation. This process uses caustic soda to alter and refine the structure of the cotton fibres. The fibres swell, becoming rounder and more uniform in nature, which gives the fabric a silky sheen and makes it more robust.    

An especially smooth surface with a silky sheen.

Perfect fit

Wrinkle-free forever… matter how much you twist and turn in your sleep. All our fitted sheets fit perfectly. Even the next morning. Without ironing!

The very high-quality jersey knit and small amount of elastane make a great team.

Picture this: You can really stretch the sheet out so that it wraps perfectly around the corners and underneath the mattress. The sheet will sheathe the mattress without a wrinkle, because after being stretched out, the fabric contracts back again. What we’re talking about is that wonderful combination of elasticity and elastic recovery.


We recommend you wash your sheet 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.

Finally, thanks to a thick elasticated border, the edges of our fitted sheets always stay where they belong. Under the mattress.           

For every bed

A solution for ALL mattresses – as if

  • Bed types

    Bella Donna Premium provides a perfect, wrinkle-free fit on all mattresses. Also on boxspring beds, futon mattresses and waterbeds.

  • Mattress thickness

    Our Bella Donna Premium sheet comes in three versions depending on the thickness of your mattress:

    •  Our standard sheet fits mattresses up to 30 cm thick
    •  La Piccola sheets are suitable for toppers up to 12 cm thick
    •  Alto sheets 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.


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 Premium 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 sheet 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.

TIP: If you know the dimensions (WxLxT) and the approximate hardness/softness of your mattress, your specialist retailer can find the perfect sheet size for you.

Exquisite ingredients

So much goodness inside

Not all cottons are alike

The fine yarn for your bed: Supercombed, long-staple cotton produces particularly fine and even single cotton yarns. Twisting two of these yarn strands together gives you a particularly tear-resistant, robust ply yarn. Gassing removes any protruding filaments using a flame, making the ply yarn even more uniform. Finally, the last protruding fibre ends are removed. It is these protruding fibre ends that tend to form little balls when a fabric is used, otherwise known as pilling. Not something that happens with our sheets! With Bella Donna Premium, the fabric undergoes an additional process of mercerisation in which the cotton fibres become rounder and even less sensitive to external damage. This process is what gives our Bella Donna Premium its exceptional longevity.

No pilling thanks to finest yarns and mercerisation.

Wonderful, elegant colours

Bella Donna Premium is remarkable for its particularly fine, small and tight knit. We then add double mercerisation to make the yarn fibres more consistent – wonderfully round and even, in other words. This uniformity means the colours appear very harmonious and the sheet gets a fantastic sheen, which is further enhanced by the addition of aloe vera and argan oil.        

Brilliant colours, even after many washes.       

Exceptional combination: elegant and functional

Our Bella Donna Premium contains the largest amount of cotton yarn, compared to our other jersey products. The more yarn and the finer the knit, the more stable the sheet. This results in a really heavy, opaque sheet with a difference you can feel. Thanks to mercerisation, Bella Donna Premium has a wonderfully smooth and beautiful surface finish.

A beautifully heavy sheet.        


Finest materials, naturally tested and certified

Cotton is a wonderful raw material, but unfortunately it doesn’t grow in Germany. We source our cotton 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. Unlike many, we do not outsource our cutting and sewing to low-wage countries. Instead around 95% of our sheets are made here in Germany. A small but vital part is also carried out a family business in Slovakia.

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

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.

Easy to change

Especially when it comes to larger bed sizes 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?"

All our Bella Donna Premium fitted sheets come 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.     

Find the clever corner – and your sheet fits perfectly first time.
