Description
Your Mattress Deserves the Same Care as the Bedding Above It
A premium mattress is one of the most significant sleep investments you can make — and a mattress protector determines whether that investment is maintained or progressively degraded by moisture, bacteria, and dust mites. The Formesse Bella Donna Clima is the mattress protector that premium mattress owners choose: a high-performance protection system with a 100% TENCEL™ Lyocell terry surface that manages moisture actively, creates a naturally inhospitable environment for dust mites and bacteria, and fits every mattress format with a precision that standard protectors cannot match.

100% TENCEL™ Lyocell Terry Surface — Active Moisture Management
The Bella Donna Clima’s most important feature is its terry surface made entirely from TENCEL™ Lyocell — not blended with cotton, not coated with chemical treatments, but pure TENCEL™ Lyocell at the contact surface.
TENCEL™ Lyocell is a natural cellulose fibre derived exclusively from sustainably certified wood — it absorbs moisture significantly more effectively than cotton, stores it within the fibre structure, and releases it back into the air during the day. This continuous moisture cycle means perspiration is drawn away from the sleeping surface as it occurs, preventing the moisture accumulation at the mattress surface that creates the warm, humid microclimate in which dust mites and bacteria thrive.
The key distinction: the Bella Donna Clima provides natural dust mite and bacteria protection without any chemical anti-mite treatments or artificial additives. The protection works because the TENCEL™ Lyocell surface consistently denies mites and bacteria the moisture environment they require — a biological approach that does not wear off with washing and cannot trigger chemical sensitivities.
Fitted Sheet Format — No Visible Edges, Perfect Surface
Unlike conventional mattress protectors that sit loose on the mattress surface or use basic elastic loops at the corners, the Bella Donna Clima uses Formesse’s fitted sheet format — it envelops the entire mattress and is held in place by a robust elasticated border tucked under the mattress on all sides.
The practical result: the protector is completely invisible beneath the fitted sheet — no raised edges, no bunching at the corners, no visible border through the sheet. The sleeping surface is beautifully smooth and even, as if the protector were not there. The Clever Corner — a sewn label at one corner — aligns with the top-right or bottom-left corner of the mattress for easy, consistent fitting every time.
Combi Sizes — One Size Fits Multiple Mattress Dimensions
Formesse’s combi size system allows a single protector size to fit a range of mattress dimensions — a direct result of the fabric’s exceptional elasticity. A Size 13, for example, fits any mattress from 140 to 160cm wide, 200 to 220cm long, and up to 30cm thick. This means you are not locked into a single exact dimension — the protector stretches precisely to your mattress rather than requiring millimetre-accurate sizing.
Three thickness versions are available:
- Standard — fits mattresses up to 30cm thick
- La Piccola — fits toppers up to 12cm thick
- Alto — fits mattresses up to 45cm thick (boxsprings, mattress-plus-topper combinations)
The Bella Donna Clima is specifically recommended for latex and highly elastic mattresses, and is fully compatible with electric adjustable bed bases — the elasticity of the fabric flexes smoothly with the base’s movement.
TENCEL™ Lyocell — Sustainable from Forest to Finished Product
TENCEL™ Lyocell is derived from wood sourced exclusively from sustainable, certified, and controlled forestry following the stringent Lenzing Wood and Pulp Policy. Its production process is a closed loop — the solvents used in spinning are recovered at 99% and reused, with high resource efficiency and minimal ecological impact.
All TENCEL™ Lyocell fibres are certified biodegradable and compostable under industrial, home, soil, and marine conditions. The Bella Donna Clima’s full composition is 82% TENCEL™ Lyocell, 16% polyester, 2% elastane — certified to OEKO-TEX® Standard 100. Formesse’s packaging is 0% plastic, 93-95% recycled paper, and the company works with ClimatePartner AG to support climate protection projects.
Made in Germany by Formesse — a third-generation family business from the Black Forest with over 70 years of experience in precision textile manufacturing.

FAQ:
Q: How does the Bella Donna Clima protect against dust mites without chemical treatments?
The Bella Donna Clima’s mite protection works through moisture management rather than chemical intervention — and this is a meaningful distinction that matters for long-term performance and for those with chemical sensitivities.
Dust mites require a warm, humid microclimate to survive and reproduce — they thrive when the sleeping surface retains moisture from perspiration overnight. The TENCEL™ Lyocell terry surface addresses this at its root: it absorbs moisture from the sleeping surface as it occurs, stores it within the fibre structure, and releases it back into the air during the day. The mattress surface consistently remains drier than mites require for their biological cycle.
Chemical anti-mite treatments — used in some protectors — can cause skin irritation in sensitive individuals, and their efficacy diminishes with each wash as the chemical coating degrades. TENCEL™ Lyocell’s moisture management is an intrinsic property of the fibre itself — it does not wash out, does not require refreshing, and cannot trigger chemical sensitivities. The same mechanism that prevents mite colonisation also inhibits bacterial growth and eliminates the moisture source for unpleasant odours — three protections from a single natural property.
Q: What is the difference between the Standard, La Piccola, and Alto versions — which do I need?
The three versions address different mattress and topper thickness profiles:
Standard fits mattresses up to 30cm thick — this covers the majority of mattresses including most memory foam, spring, and hybrid models up to standard depth. It is the correct choice for most standalone mattresses.
La Piccola is specifically designed for toppers up to 12cm thick — it fits the topper as a separate item rather than the mattress below. If you use a TEMPUR® or Technogel topper on your mattress, La Piccola provides a protector specifically sized and profiled for the topper’s shallower depth.
Alto fits mattresses up to 45cm thick — designed for very thick mattresses, boxspring beds, and mattress-plus-topper combinations used simultaneously. If you have an adjustable bed base with a full-depth mattress and topper placed together, Alto is the appropriate version.
For standard mattresses — including TEMPUR®, Dorelan, Technogel, and Schramm models in Sleep Gallery’s range — the Standard version is the correct choice for most configurations.
Q: Is the Bella Donna Clima compatible with TEMPUR® and memory foam mattresses?
Yes — the Bella Donna Clima is specifically recommended for mattresses made from highly elastic materials, including TEMPUR® foam, memory foam, and natural latex, for two specific reasons.
First, the combi size system and the fabric’s exceptional elasticity mean the protector conforms precisely to the mattress’s profile — including the slight dimensional variation that compressed memory foam can exhibit when loaded. A standard protector with limited stretch may slip, bunch, or pull tight at the corners under these conditions. The Bella Donna Clima’s elasticated construction stretches evenly with the mattress.
Second, TEMPUR® and memory foam mattresses are temperature-sensitive — they respond to body warmth — and anything placed over them that restricts airflow or thermal transfer affects their performance. The TENCEL™ Lyocell surface is breathable and moisture-wicking rather than insulating — it allows the mattress to perform as designed rather than creating a thermal barrier above it.
The Bella Donna Clima is also fully compatible with electric adjustable bases — the flexible fabric moves smoothly with the base’s adjustment rather than restricting movement or developing stress points at the fold zones.
Q: The Formesse Bella Donna Clima costs more than standard mattress protectors — what justifies the price?
The price reflects three specific distinctions from a standard mattress protector.
First, the TENCEL™ Lyocell terry surface: 100% TENCEL™ Lyocell at the contact surface — not a cotton-Lyocell blend, not a synthetic microfibre — represents a material specification that generic protectors do not reach. TENCEL™ Lyocell’s superior moisture absorption, its closed-loop sustainable production, and its natural mite-inhibiting properties are all properties intrinsic to the pure fibre, not to a diluted blend.
Second, the fitted sheet format with combi sizing: the precision engineering that allows a single protector to fit a range of mattress dimensions — through genuinely exceptional fabric elasticity — requires a more sophisticated knitting specification than standard protectors. Formesse’s knitting facility operates up to 3,000 yarn spools and 25,000 needles simultaneously to achieve the specific elasticity characteristics their combi sizes require.
Third, German manufacturing to Formesse’s standards: over 70 years of family-business production in the Black Forest, with OEKO-TEX® Standard 100 certification, ClimatePartner climate certification, and sustainable packaging. A protector that lasts for years without degrading in performance — protecting a mattress investment that cost many times its price.
