Beaver or microfiber: Which winter bedding really keeps you warm?
In November, the same question arises in many households: Should it be the cozy cotton Biber bedding or the significantly cheaper microfiber? Both feel warm to the touch – and both have convinced followers. A blanket answer to the question Biber or microfiber is nevertheless not possible, because the two qualities handle heat, moisture, and your washing routine differently.
What really matters when making the decision
The fiber. Biber is brushed cotton. The raised fiber ends form a cushion of air that retains body heat – biberna invented this quality in 1968, and it remains the core product of the company to this day. Microfiber, on the other hand, consists of very fine polyester fibers. They also trap air, but absorb hardly any moisture.
Moisture management. This is the decisive difference. Cotton can absorb a considerable amount of moisture without feeling wet. Anyone who sweats at night will notice it immediately: Biber keeps dryness under control. Microfiber tends to wick moisture away rather than store it – with heavy night sweats, this can make the cover feel clammy more quickly.
The weight. Biber weighs around 160 g/m² and is therefore noticeably felt on the body. Microfiber is significantly lighter. Those who find weight in bed pleasant will make a different choice than someone who wants to feel nothing at night.
The price. The gap is largest here: Castell microfiber sets start at €18.95, while a biberna Fine Biber set costs €49.95. Castell is our entry-level brand, biberna the premium brand – both with the same quality standards, but aimed at different requirements.
Biber and microfiber in direct comparison
| Quality | Properties | Ideal for | Price range |
|---|---|---|---|
| Fine Biber (100% cotton) | Brushed, fluffy, breathable, absorbs moisture, wash-resistant | Cool bedrooms, people with night sweats, sensitive skin | approx. €49.95–59.95 |
| Melange Flannel (100% cotton) | Woven from differently colored yarns instead of printed, finer feel, just as warm as Biber | Those who want Biber warmth with a softer feel and a mottled look | approx. €49.95–79.95 |
| Microfiber (polyester) | Very light, quick-drying, non-ironing, colorfast, low moisture absorption | Second sets, guest beds, frequent washing, small budget | approx. €18.95–27.95 |
| Microfiber Satin (polyester) | Smoother, slightly shiny surface, cooler initial contact than classic microfiber | Those who like it smooth but still want to keep costs low | approx. €23.95 |
Which one is right for you?
You get cold and heat sparingly. Then there is no alternative to cotton. The biberna Fine Biber bedding (Art. 0006722) from €49.95 retains body heat without making the bed stuffy. You can find more designs in the Biber bedding.
You sweat at night. This is where cotton shows its strength – with a finer feel: The biberna Melange Flannel bedding (Art. 0840500) is woven from differently colored yarns in our own weaving mill in Hamminkeln and is therefore mottled instead of printed. It warms just as much as Biber, but feels finer.
You need a second or guest set. If the cover only goes on the bed a few weeks a year, microfiber is the sensible choice: The Castell Microfiber bedding (Art. 0560500) costs from €18.95, is non-ironing, and is quickly ready to use again after washing. The entire selection shows the Microfiber bedding.
You like it smooth, not fluffy. Then brushed Biber is the wrong direction. The Castell Microfiber Satin bedding (Art. 0560961) has a smoother surface and stays cooler when you lie down – often the more pleasant solution for well-heated bedrooms.
What is often overlooked with Biber and microfiber
Lint at the beginning. Brushed cotton loses loose fiber ends in the first few washes. This is normal and stops – it is not a quality defect. Microfiber hardly pills, but instead attracts hair and dust more easily because it becomes statically charged more easily.
Drying. Microfiber is dry in a short time and does not need to be ironed. Biber takes longer, but becomes nice and fluffy again in the dryer – an advantage that many underestimate.
Durability. A good cotton set will accompany you for many winters. Microfiber is cheaper to purchase, but shows pilling earlier at friction points with intensive use. Those who use a set daily for years usually fare better with cotton.
Fit. Check the dimensions of your duvet before purchasing. A cover that is too large will flap around, one that is too small will pull tight – you will notice both every night, regardless of the material.
Frequently Asked Questions
Does microfiber warm as well as Biber?
Microfiber quickly feels warm when you lie down because it is very light and hardly releases heat. However, over the whole night, the heavier, brushed Biber retains body heat more evenly – especially in cool bedrooms.
Is microfiber suitable for allergy sufferers?
Microfiber can usually be washed without problems and is therefore easy to clean. Those who react sensitively to synthetic fibers or sweat heavily generally fare better with cotton. An overview is provided by our Allergy bedding.
Does Biber bedding scratch?
No. The brushed nap feels fluffy, not rough. What is sometimes perceived as scratching is actually a stiff feel due to too much detergent or hard water. Fabric softener coats the nap and flattens it over time – it is better to omit it.
How much does shipping cost?
Nothing. We deliver all products within Germany free of shipping costs, without a minimum order value.
Why is Biber directly at biberna cheaper than expected?
Because you are buying directly from the manufacturer. biberna invented Biber bedding in 1968 and has been manufacturing textiles in Hamminkeln since 1932. In retail, high-quality varieties have often been replaced by cheap goods – in direct sales you get the original quality at a price-performance ratio that hardly exists anymore.
Which quality is suitable for the guest room?
Ease of care is paramount there. Microfiber is quick to wash, non-ironing, and cheap – ideal when the bed is only occasionally occupied. If it should be particularly cozy for guests, opt for Fine Biber from the Winter bedding.
