How often should you change your bedding — and how long does it last?

There is a particular feeling in settling into a peaceful bed with cool, smooth bedding against the skin. That feeling is not random — it is the result of the right bedding and the right routine. One of the most common questions we get is about exactly that routine: how often should you really change your bedding, how often do the sheets need washing, and how long does a truly good duvet cover set last? The answers are simpler than many think, and once they are second nature, the well-made, fresh bed becomes a natural part of everyday life rather than a project. Here we go through the intervals, the care and the signs that it is time to replace — so you can bring the hotel feeling home and keep it, night after night.

How often should you change sheets and pillowcases?

The short version: change and wash sheets and pillowcases roughly once a week. That is the interval that recurs among independent sleep and health resources, and it is a good rule of thumb for the vast majority. During a night the skin gives off moisture, skin cells and skin oils, and all of this gradually gathers in the textiles closest to the body. A weekly routine keeps the bed fresh and pleasant without becoming a time-consuming project.

According to the independent American Sleep Foundation, most people should wash their sheets roughly once a week, and the pillowcase just as often. The pillowcase deserves particular attention since it is in direct contact with face and hair night after night — many therefore choose to change the pillowcase a little more often than the rest.

When you should wash more often

• If you sweat a lot or sleep warm — in summer or with a thicker duvet.
• If you have allergies or sensitive skin, where fresh textiles make everyday life easier.
• If pets sleep in the bed, which adds both hair and particles.
• If you sleep with make-up, skincare or hair products that transfer to the pillowcase.

In these cases, an interval of every three to four days may suit better — listen to your own everyday life rather than the calendar.

How often should you change the duvet cover and pillowcase?

The duvet cover and the pillowcase outer are what lie closest to you, and so they are washed every week. The duvet and pillow themselves — the inners — need washing far less often, however, since they are protected by their covers. A reasonable interval for washing the duvet and pillow themselves is a few times a year, or according to the manufacturer's care advice on your particular product.

For those who want to build a considered routine, we have gathered more detailed washing and care advice in our guide to bedding care. There we go through temperature, folding and how to preserve both colour and fit over time.

Dust-mite considerations for the sensitive

For those with a dust-mite or dust allergy, the wash temperature matters. Sweden's 1177 advises people with a dust-mite allergy to wash sheets at 60 degrees, and to wash pillows and duvets at 60 degrees regularly. The Astma- och Allergiförbundet also stresses that bed textiles should preferably withstand washing at at least 60 degrees. This is general hygiene advice from health resources and not a medical promise — if you have symptoms, you should always consult healthcare. If you want to delve deeper, we have also written about allergy-friendly bedding and how material choice and routine go hand in hand.

How long does quality bedding last?

This is where the real difference between cheap and well-built lies. Bedding of genuine cotton yarn, woven with care, is made to be washed again and again — that is rather the whole point. Tightly woven percale in long-staple cotton often becomes softer and more supple with each wash, while the weave holds its shape. Yarns of extra-long staple fibre, as in our Supima collection, are known for their strength and their ability to keep their lustre over time with the right care.

How long a set lasts depends in practice more on care than on the calendar. Washing at the right temperature, mild detergent without fabric softener, and drying without unnecessary heat — this is what decides whether a quality set ages beautifully or wears out prematurely. Rotating between two or three sets, so that no single set is washed every week all year round, is one of the easiest ways to extend the life of your entire bedding wardrobe.

Signs that it is time to replace

• Thinner, see-through weave — especially in the middle where the wear is greatest.
• Persistent fraying, holes or frayed seams that cannot be mended.
• Lost softness where the fabric feels rough or lifeless despite correct washing.
• Elastic in fitted sheets that has lost its stretch and no longer stays in place.
• Stubborn discolouration or odour that does not come out in the wash.

Build a routine that lasts

The lovely thing about a good bed routine is that it almost takes care of itself once it is in place. A couple of simple habits make the biggest difference:

• Have at least two sets per bed. Then you can change straight away and wash at a calm pace. A complete duvet cover set makes the swap seamless.
• Air the bed in the morning. Throw back the duvet for a while before you make the bed, so the moisture has time to evaporate.
• Wash like with like and follow the care advice — that is where longevity is decided.
• Rotate your sets across the seasons for even wear.

If you are looking for a starting point, our Ralph duvet cover set and Regency Lee duvet cover set are built for exactly this kind of everyday rotation — beautiful enough to long to come home to, and made to be washed often. And since bedding is such a large part of the quality of the night, we have also written about the connection between bedding and sleep.

Frequently asked questions

How often should you change sheets?

Roughly once a week for most people. Change and wash sheets and pillowcases weekly, and more often — every three to four days — if you sweat a lot, have allergies or share the bed with pets.

How often should you wash pillowcases?

As often as the sheets, that is, roughly every week. Since the pillowcase lies against the face and hair, many choose to change the pillowcase a little more often.

How often should you wash the duvet and pillow?

The duvet and pillow themselves only need washing a few times a year, since they are protected by the duvet cover and pillowcase that are washed every week. Always follow the care advice for your specific product.

What temperature should you wash bedding at?

Follow the item's care advice. For those with a dust-mite allergy, 1177 recommends washing at 60 degrees to reduce mites — a general hygiene tip, not a medical promise. If you have symptoms, consult healthcare.

How long does quality bedding last?

With the right care, bedding in tightly woven, long-staple cotton lasts a long time and can become softer with each wash. Longevity is governed more by care than by age — replace it when the weave thins out, the softness disappears or the seams and elastic give way.
