New bedding is one of life’s smaller pleasures. The crisp fold, the clean smell, the satisfying crackle of the packaging. Then comes the question nobody enjoys answering on a Sunday evening. Does it need washing first?
Plenty of us are in that position right now. Our 2026 UK Sleep Survey found that one in five people are sleeping under a duvet they’ve had for a year or less.
The lowdown: Wash new sheets, covers and protectors before you sleep in them. Fabric may arrive carrying finishes, loose dye or dust from its journey to you, and a first wash clears whatever is there while softening the material. Follow the care label, wash deep colours on their own the first time, and skip all this for a new duvet, which only needs a shake and a clean cover.
Give new sheets, covers and protectors one wash before you sleep in them. New fabric has been through a lot before it reaches your bed. Dyeing, finishing, cutting, pressing, folding, packing, shipping and sitting in a warehouse. A wash settles all of that, and it has the happy side effect of softening everything up.
Our own pillow buying guide gives the same advice for new pillows, suggesting a wash before first use to soften the filling and clear any manufacturing dust.
It depends entirely on the fabric, and in plenty of cases, the answer is very little. Here’s what can be there, which explains why that first wash makes such a difference in how bedding feels:
Then there’s formaldehyde, which sounds far more dramatic than it is. Some crease-resisting resins release it, though plenty of fabrics never go near them. A 2022 study of baby and maternity clothing found it in 20% of the garments tested, all at levels within legal limits, and none at all in the samples that had been washed. The researchers recommended washing clothing before first use. That study looked at clothing rather than bedding, so treat it as a useful pointer instead of the final word. The practical takeaway is the same either way.
Mostly, it changes how bedding feels. Those crease-resisting finishes wash out, so the fabric relaxes and takes any loose dye and dust with it.
Washing a deep colour on its own also means any loose dye comes out in the machine instead of on a light mattress or a white duvet.
Then there’s the benefit that’s harder to measure. Bedding washed at home smells like your house rather than a warehouse, making the first night in it feel like yours.
The care label always wins, whatever an article says. Beyond that, a few things make the first wash go more smoothly:
Once it’s on the bed, our three easy ways to put on a duvet cover will save you from wrestling with it. After that, washing every week or two keeps things fresh, as our guide to how often you should wash your bedding explains.
Sheets and covers are the easy part. The thicker items each have their own answer:
Some people may react to new fabric, and dyes and finishing resins are among the usual suspects. The same review on textile dermatitis suggests that, with polyester, lighter colours tend to be a safer bet than darker ones.
Washing before first use may help. If a particular set still bothers you, our hypoallergenic bedding and natural bedding ranges are good places to look, and it’s worth speaking to a pharmacist or GP if your skin keeps flaring up.
Yes. A first wash clears any finishes, loose dye and dust that new fabric may have brought with it, and it tends to soften the material at the same time. Follow the temperature on the care label and wash the set on its own the first time.
Whatever the care label says. Cotton bedding is often fine at 40 degrees, while linen, silk and delicate weaves usually ask for cooler temperatures. A hotter wash than the label allows risks shrinking the fabric or fading the colour.
Most do. The stiffness tends to ease after the first wash, and cotton keeps relaxing over the next few.
Usually not. The cover is what you sleep against, so a clean cover and a good shake to settle the filling are enough. Washing comes in later, once it needs freshening up.
Where the care label allows it, yes. A wash softens the filling and freshens it up before the first night. Memory foam is the exception, as it usually needs spot cleaning or a wash of the cover only.
