Sheets and duvet covers: percale or sateen, and the thread count that misleads
Partilhar
Buying sheets looks like the simplest decision in the bedroom and it is the one that most often goes wrong. Two reasons: almost nobody knows the difference between percale and sateen, and almost nobody buys the right size.
I am Ana Cristina, Dreamura's Sleep Advisor. This guide settles both.
Percale and sateen: it is not the material, it is the weave
Percale and sateen can be exactly the same cotton. What changes is how the threads cross on the loom.
Percale is a simple cross: one thread over, one thread under. It gives a matte fabric, with the look of a cotton shirt, with more air between the threads. It is cool to the touch and stays cool through the night.
Sateen lets several threads pass before crossing. That puts more thread on the surface, which gives a subtle sheen and a silky feel, and closes the fabric. It is warmer and falls with more weight over the body.
The choice between the two is about temperature, not quality. If you get warm at night, percale. If you feel cold or want the hotel sensation, sateen. There is no better one — there is one that is right for you.
A practical note: percale creases more and makes no secret of it. Sateen hides creases better, but shows water marks more. If you hate ironing, percale washed and hung straight out of the machine sorts itself out.
Thread count: where it stops meaning anything
Thread count records how many threads there are in a square inch of fabric. It is a useful indicator — up to a point.
- Below 180 threads — the fabric is thin and it shows. It survives fewer washes.
- 200 threads — the level of everyday cotton. This is the percale of the Pākēru line.
- 300 threads — higher density, softer feel. This is the sateen of the Saten line.
- Above 400 threads — this is where the problem begins.
To get past 400, the industry frequently uses finer threads twisted together and counts each ply as one thread. A sheet advertised at 800 threads may hold less cotton than an honest 300. Above 400, the number becomes a sales argument rather than a measure of quality.
What is genuinely worth checking, in order: composition (100% cotton or a blend), type of weave (percale or sateen), and only then the thread count.
Pure cotton or a polyester blend
This is not a question of purity. They are different trade-offs.
100% cotton breathes better, absorbs perspiration and is cooler. In exchange it creases more, dries more slowly and costs more.
A polyester blend (the Bakuri line is 50/50) creases far less, dries quickly and stands up better to heavy use. It breathes less — anyone who gets warm at night will notice.
The blend makes sense in children's rooms, in guest beds that are changed often, and in short-term rentals, where turnover and drying count for more than the feel. Pure cotton makes sense in the bed you sleep in every night.
The size: the mistake almost everyone makes
This is where most money is lost on bed linen, and the cause is always the same.
A fitted sheet is not chosen by the width of the bed. It is chosen by the HEIGHT of the mattress.
A 140 cm bed with a 20 cm mattress and a 140 cm bed with a 30 cm mattress need different sheets. In the second case, a sheet designed for 20 cm does not go round — either it does not fit, or it fits and jumps off the corner on the first night.
Before buying, measure the height of your mattress. If you add a topper or a protector, add that thickness too. Dreamura mattresses run from 12 to 30 cm, and the Samurai, at 30 cm, is the case where this matters most.
On a duvet cover the reasoning is different: there the size follows the duvet, not the bed. A 220x240 duvet calls for a 220x240 cover, even if the bed is 160.
The Dreamura bed linen lines
There are 41 references in the bed linen collection, organised into lines. Each line is a weave, and exists in four or five colours.
| Line | Weave | Composition | For |
|---|---|---|---|
| Pākēru | 200-thread percale | 100% cotton | Everyday use, anyone who gets warm at night |
| Saten | 300-thread sateen | 100% cotton | Silky feel, anyone who feels cold |
| Norudikku | 200-thread cotton | 100% cotton | Duvet covers, Nordic design |
| Neru and Kiyo | 200-thread percale | 100% cotton | Sheets, shorter colour range |
| Kanjiru | 300-thread sateen | 100% cotton | Satin-finish sheets |
| Bakuri | Blend | 50% cotton, 50% polyester | High turnover, little ironing |
| Kihon | Fitted bottom sheet | 50/50, elastic all the way round | When only the fitted sheet is missing |
Prices on a 140/160 cm bed: Bakuri sheets 54 €, Pākēru 84 €, Saten 89 €. Pākēru duvet cover 74 €. Kihon fitted bottom sheet 29 €. Three-year warranty, made in Portugal.
And the duvet inside the cover
The cover is the fabric; the duvet is the filling. The number that decides the duvet is the weight, in grams per square metre.
- Around 300 g/m² — year-round use in homes with stable temperature. This is the Iro, from 59 €.
- Around 350 g/m² — winter, or cold homes. This is the Yume, from 39 €.
A well-insulated house with central heating calls for a lower weight than an old flat with no insulation, for the same person. Duvet weight is a poor thing to replace with extra blankets: a duvet that is too light plus two blankets on top gives weight without giving insulation.
How often to wash, and at what temperature
The sheets on the bed you sleep in every night should go in the machine once a week, or every two weeks in winter if you sleep in pyjamas and do not perspire much. A duvet cover holds up for two to three weeks.
In cotton, 60 °C is the temperature that kills dust mites. If the fabric will not take 60, wash at 40 and put whatever is not washable in the freezer — it works for the same reason. And do not use fabric softener on cotton sheets: it leaves a film that reduces absorption, which is exactly what you bought cotton to have.
Two questions settle almost any sheet purchase: whether you get warm or feel cold at night, and how tall your mattress is. The first decides percale or sateen. The second decides the size. The rest is colour.

Frequently asked questions
What is the difference between percale and sateen?
It is the weave, not the material — they can be the same cotton. Percale crosses one thread over and one under, and stays matte and cool. Sateen lets several threads pass before crossing, which gives a subtle sheen, a silky feel and more warmth. The choice is about temperature: percale for those who get warm, sateen for those who feel cold.
How many threads should a good sheet have?
Between 200 and 300 threads covers the vast majority of cases. Above 400, the number becomes a sales argument: getting there involves fine twisted threads with each ply counted, so an 800-thread sheet may hold less cotton than a 300. Check the composition and the weave first.
How do you choose the size of a fitted sheet?
By the height of the mattress, not the width of the bed. Two 140 cm beds with 20 cm and 30 cm mattresses need different sheets. If you use a topper or a protector, add that thickness too.
Pure cotton sheets or a polyester blend?
Pure cotton breathes better and is cooler, but creases more and dries slowly. The polyester blend creases less, dries quickly and stands up better to heavy use, but breathes less. The blend pays off in children's rooms, guest beds and short-term rentals.
How often should sheets be washed?
Once a week on a bed in daily use, or every two weeks in winter if you sleep in pyjamas and perspire little. A duvet cover holds up for two to three weeks. In cotton, 60 °C is the temperature that kills dust mites.
What weight should a duvet be?
Around 300 g/m² for year-round use in homes with stable temperature, and around 350 g/m² for winter or cold homes. The Dreamura Iro duvet is 300 g/m² and the Yume is 350 g/m².
