Nights are getting cooler, the heating is back on – and suddenly summer bedding feels much too thin. Adjusting your bedroom now doesn't mean replacing your entire setup. It's enough to adjust the right elements: material, duvet filling and room climate. This guide explains which fabrics keep you warm in autumn and winter, how flannel and brushed cotton differ, which duvet suits the cold season, and how to store your summer bedding properly until spring.
As the heating season begins, the climate in your own bedroom changes too: the air becomes drier, temperatures fluctuate more, and lightweight summer bedding often isn't enough anymore. A few targeted adjustments in the bedroom are all it takes to get through the transition without freezing or overheating.
The layering principle for your bed
Instead of switching straight to the thickest winter duvet, it's worth applying the same principle that works well for winter clothing: several thinner layers instead of one heavy one. A light flannel cover combined with a wool blanket at the foot of the bed can be adjusted more flexibly than a uniformly thick quilt. On mild autumn days, you simply remove one layer without changing the entire bedding setup.
Which material suits the cold season?
Weight and weave distinguish bedding far more than appearance – and that's exactly what determines how warm or cool it feels.
Flannel and brushed cotton: the classic winter materials
Flannel is brushed on both sides and usually weighs between 140 and 180 g/m², which gives it its soft feel and noticeable warmth. Brushed cotton (Biber) is similar but usually a bit lighter at 120 to 140 g/m² and brushed on one side only. This makes it smoother than flannel, but it stays noticeably warmer than smooth summer fabrics.
Renforcé and percale remain relevant in the transition period
Renforcé is a densely and smoothly woven cotton fabric, typically 100 to 140 g/m², suitable for year-round use – a compromise between summer and winter bedding. Percale, with its silky-smooth surface, retains less warmth and is therefore better suited to the warmer season.
Choosing the right duvet for autumn and winter
Alongside the cover, the duvet's filling plays an equally important role. Duvets are broadly divided into summer, transitional, and winter duvets, with the fill weight per square meter determining the warmth level: winter duvets generally have a considerably higher fill weight than summer duvets, regardless of whether the filling is down, feather, or synthetic. If you'd rather not buy two complete duvets, a combination duvet made of two parts that button together is an option – both layers together in winter, just the lighter one in summer.
Room climate: temperature and humidity in the bedroom
A bedroom temperature between 16 and 18 degrees is often recommended – noticeably cooler than what's typical in living rooms. When the heating is turned up in autumn, humidity often drops at the same time, which can contribute to dry mucous membranes and restless sleep. Regular quick airing before bed exchanges the air without letting the room cool down permanently.
Winter care: don't forget to change your bedding
Even in the cold season, the same rule applies: bedding should be changed every one to two weeks, regardless of material. Skin flakes, sweat, and dust accumulate all year round, even if thicker fabrics make this less noticeable. Flannel and brushed cotton can generally be machine washed at 40 to 60 degrees, but should be washed once before first use, since brushing can loosen fibers.
Storing summer bedding properly
Before the winter bedding goes on the bed, summer bedding should be washed and completely dried – any residual moisture encourages mildew stains during longer storage. A cotton bag or a breathable fabric cover is better suited for storage than an airtight plastic bag, since cotton, unlike plastic film, lets moisture escape. A dry, not overly warm cupboard keeps the textiles in shape until next spring.
The seasonal switch as a small ritual
The seasonal changeover doesn't have to be a big undertaking. Choosing one or two materials – flannel for cool nights and Renforcé for the transitional period, for example – means fewer changes to get through the cold season than relying on a single set of bedding all year round. To finish the switch, a few decorative cushions in warmer colours and richer textures complete the look for the colder months.
