In short: Flannel bedding is a tightly woven, brushed fabric made of 100% cotton with a weight of around 160 g/m². The brushed pile traps countless tiny air pockets, thus retaining body heat while remaining breathable. biberna invented this quality in 1968 and continues to offer it in original quality to this day.
When the nights get cooler, the same question repeatedly arises in search queries and consultations: What exactly is Flannel bedding? The name sounds like an animal, but has nothing to do with it. It refers to a special cotton fabric – one that originated in our company. In this guide, we explain how Flannel is made, how to recognize good quality, and which of the warm qualities is right for your bedroom.
Flannel bedding: the fabric behind the name
Flannel is not a fiber, but a finish. It starts with a tightly woven cotton fabric that is then brushed. Fine carding rollers draw individual fiber ends from the fabric to the surface. This creates a soft, fluffy layer – the so-called pile. This pile is exactly what gives it its characteristic feel when you get into bed: the bedding feels warm immediately, rather than initially surprising you with its coolness.
The effect is easily explained by physics. The raised fibers trap countless tiny air pockets, and still air is an excellent heat insulator. Flannel therefore does not actively warm you, but retains body heat where it belongs. Because the base fabric is made of 100% cotton, the bedding remains breathable and absorbs moisture – a crucial difference compared to warming synthetic fiber qualities.
Good Flannel has a weight of around 160 g/m². This figure is a solid benchmark, but not the whole story: yarn quality, weave density, and above all, the care taken during brushing are crucial. If brushed too aggressively, the bedding feels impressively fluffy at first – but loses its pile after a few washes. You can read more about this in our article on bedding weight.
How to recognize good Flannel bedding
In retail, there can be worlds of difference between two duvet covers that are both called "Flannel". These five features will help you assess them:
-
Material specification: 100% cotton. Blended fabrics with polyester also provide warmth, but are less effective at transporting moisture.
-
Even pile: Run your hand over the surface. High-quality Flannel feels equally dense everywhere, without thin patches.
-
Workmanship: Clean seams and a high-quality zipper instead of buttons or a hotel closure. Experience shows that the closure is the first component to fail on cheap products.
-
Color depth: Well-dyed products remain vibrant even after many washes.
-
Origin and quality control: Ask who is responsible for the quality. Our fine Flannel sets are manufactured according to biberna specifications, inspected in Hamminkeln, and shipped; we weave our melange flannel in our own weaving mill in Hamminkeln.
This is exactly where we start: biberna is the inventor of Biber bedding (brushed cotton flannel). Founded in 1932 as a small contract weaving mill of the Schmänk family in Hamminkeln, the company developed the quality that has underpinned the brand name to this day in 1968. Since then, Flannel has been the company's core product – supplemented by melange flannel since 2012. We tell the story of how this came about in the history of Flannel bedding and on our history page.
A tip that saves many customers money: over the years, traditional retail has frequently replaced classic qualities with cheaper imported goods. That is why we offer original quality directly – find our Flannel bedding here at the direct manufacturer price.

"Flannel" is not a single product in our range, but a family. The following table shows how the variants differ – and where the smooth alternative makes more sense.

The prices stated are direct prices starting from a 135x200 cm set and vary depending on size and design. The price on the product page is always the decisive one.
Who Flannel bedding is worth it for – and who it is not
Flannel is the right choice if you take longer to warm up in the evening, sleep in a cool bedroom (16–18°C is ideal), or simply appreciate the cozy feel. Those who like to sleep with an open window also benefit significantly. The biberna fine Flannel bedding 0006722 offers a proven entry point.
Flannel is less suitable if you sweat heavily at night or sleep in a warm bedroom above 20°C. In that case, smooth qualities are the better choice – for example from our mako satin bedding. An overview of all fabrics is available in our article on bedding fabrics.
Bridging both worlds is our own development, melange flannel, known internally as "Flannel 2.0": 100% cotton, woven from differently colored yarns instead of printed, and manufactured in our own weaving mill in Hamminkeln. It does not provide more warmth than Flannel, but offers the same warmth with a softer feel. In direct sales, it costs around €49 to €79.95.
Flannel bedding and melange flannel are popular gifts for anyone who gets cold at night. In the gift finder, both qualities can be combined with a matching fitted sheet to create a set.
Frequently asked questions
Why is it called Flannel bedding?
The name alludes to the dense, soft fur of a flannel – an image of the brushed, fluffy pile of the fabric. The bedding has nothing to do with animal hair: it is made of 100% cotton.
Who invented Biber bedding (brushed cotton flannel)?
H.u.W. Schmänk GmbH & Co. KG, now known as biberna, from Hamminkeln on the Lower Rhine. The family business was founded in 1932, developed Flannel bedding in 1968, and is now run by the third and fourth generations.
How warm is Flannel compared to flannel?
Both are brushed, warming cotton fabrics with almost identical warming performance. "Flannel" is the classic German term for this quality, while "flannel" is a more general term for a brushed fabric, often in a twill weave. You can find the detailed comparison under Biber flannel or flannel – which is warmer?.
What is the difference between Flannel and fine Flannel?
Fine Flannel is more tightly and finely woven and retains its shape better even after frequent washing; classic Flannel is more heavily brushed. You can find the detailed comparison under Fine Flannel vs. Flannel.
Is Flannel bedding easy to care for?
Yes. It can be washed at 60°C and tumble-dried – the circulating air even helps raise the pile again. Ironing is not necessary. Avoid fabric softener, as it lays the fibers flat. The sewn-in care label of the respective item is always the decisive guide.
