Everybody likes and wants a good night’s sleep. You will never hear anybody say ‘these satin sheets are great because every time I go for night-night, I slip and fall first’. Needless to say, after a long, tiring day at work or whatever, you’d want your bed to be comfortable, to say the least.

Which is why sheets are something everybody accords special importance to; people accuse men to be minimalists in this regard, and yet you’ll never see an air mattress without a Star Wars or Snoopy sheet on. So, this seemingly small part of our lives actually is much more important than we think it is, which brings us to this question: are microfiber sheets hot? But first, we’ll look into some of the more pressing questions and topics like microfiber polyester sheets and whether microfiber is cotton or some other synthetic material.

For starters, microfiber is a synthetic material, and is composed out of many different polymers and whole range of other synthetic fibres designed to retain heat. This allows for a good night’s sleep on a particularly chilly night, which could help explain why many people still prefer cotton or other materials for sheets. Furthermore, we’ll also look into microfiber GSM sheets and microfiber polyester sheets, and whether they are a good substitute to your normal, run-of-the-mill microfiber sheets.

Microfiber Sheets

As explained beforehand, microfiber is a synthetic material made of polymers, including polyester and polyamide. These two fibres give it its characteristic look and feel. Microfiber is reputed to be more durable than cotton or other natural or even synthetic fibres, more porous, therefore allowing it to dry off more quickly.

What’s more, due to it having all these abilities, microfiber presents a solution to the common problem of bedspreads and sheets: of being too delicate, requiring too many washes, among others. So, this synthetic super-fibre might be the answer to all of the peoples’ wallows on bedspreads and sheets. 

As the name implies, a microfiber is called as such because of its fiber size, which is measured in deniers; so, for a fiber to be classified and considered a ‘microfiber’, its diameter of the fiber must be less than 1 denier; this is in opposition to cotton or other fibers, whose length and deniers are significantly higher than that of a microfiber. 

Many people prefer microfiber to cotton; and of course, at the end of the day, it all boils down to personal preferences and whether or not you prefer that one pro that cotton presents or resent that one con that microfiber has; its all down to your own personal preferences. 

Cotton Sheets and Spreads

A more natural, organic and cool (literally) alternative to microfiber sheets would be cotton, the second-most used material for such purposes. Cotton is all-natural, not synthetic, and is a fibrous material composed almost purely of cellulose, making it equally durable, lightweight but not as much a heat-trapping material as is its synthetic counterpart. 

Cotton is usually preferred for bedspreads and sheets; as opposed to synthetic fibers, which retain heat and are usually only used in winter, autumn or for people who prefer more warm spreads. Cotton does not trap heat as efficiently as processed synthetic fibre, and as such, it is commonly used in light applications wherein heat retention isn’t a concern, rather heat dissipation is, which cotton is far more efficient in.

So, What’s The Difference Between The Two?

Well, just a salient description of these two can highlight in detail the differences between cotton sheets and microfiber sheets; first up is deniers. As explained above, a thread qualifies as a microfiber if it is less than 1 denier. Cotton is more than a single denier, which makes it much more heavy than a microfiber (in terms of fibrous weight).

Heat Retention:

The main arena of distinction between the two are their physical characteristics, and how these affect their consumption. First among which is heat retention or dissipation. Microfiber sheets are warm; used mostly in seasons like winter and fall, microfiber sheets retain and trap heat, allowing them to stay warmer for longer as compared to cotton.

What’s more, since they are synthetic, further modification of the thread can allow for more heat retention, making it ideal for sheets designed for colder temperatures.  Cotton, on the other hand, does not retain heat as efficiently as a microfiber sheet. That makes it a better heat dissipator, allowing it to be more suitable for cooler applications.

For instance, many people prefer cotton sheets even in less temperate winters owing to its heat dissipation factor. Summer clothes, sheets and the whole cool apparel owes much of its existence to cotton; its heat dissipation allows it to be favoured for sheets and bedspreads used in the summer and spring season, when it isn’t a little chilly. 


The second factor that differentiates the two greatly is moisture resistance. Cotton is a natural fibre and as such, is greatly moisture resistant. Which means that spills or leaks can be handled much more efficiently, plus drying these sheets is not going to take an entire lifetime and an afternoon.

Microfiber sheets on the other hand, are very moisture absorbent and not too much resistant to moisture, which automatically means that spills and sprays are going to be a problem if you are using microfiber sheets. By using the transitive property then, you can automatically assume that these sheets will take longer to dry off then their cotton counterparts; and that is solely because since they are not water resistant, have higher absorption rates, it will take a lot longer to dry them off.


Whether a bedspread or sheet is breathable or not is also an important factor. We’re not talking ‘breathing through a sheet because you’ve been kidnapped’ breathability, but rather the fact that the material that the sheet is manufactured is more airy and not warm. And of course, cotton takes the pole position here too. 

Cotton is considered a more breathable material, which could help explain why its better at cooling and is not a very efficient heat retainer. In other words, it is breathable because it dissipates heat quicker and allows for the user to not feel sweaty; especially in the case of bedspreads and clothes. Microfibers, on the other hand, are efficient at heat retention and trap heat for longer within their fibres, which could explain why they are considered less breathable than their cotton counterparts.

Then Are Microfiber Sheets Any Good?

Well, like its been stated already, its upto the user. But there are some objective pros and cons that can help a person make a decision over which kind of sheets and bedspreads would be better (if you’re that much of a nit-picking ninny). for instance, durability is a major concern among people looking to shop for some stuff. Sheets are durable in both materials; both cotton and microfibers are pretty durable and can last pretty long if taken proper care.

However, if we take cost into account and how much cost efficient in regards with their durability, and then how these two stack up, you can reach on a definitive answer. Yes, microfiber sheets are much more durable and present a much more cost-efficient answer to buying and using bedspreads and sheets over a long period of time.

This is because synthetic fibers on average have a longer shelf and use life as compared to natural fibers; and since cotton is a natural fiber with a much more delicate structure and weave, it’ll not last any longer than microfiber. The latter can, with good care and maintenance, last longer than cotton, which makes it a better choice overall. 


Microfiber sheets are objectively more comfortable than cotton ones, especially treated cotton, as they retain heat and are water absorbing, thereby allowing for better usability and comfort. Plus there’s the softness factor. Admittedly, cotton beats microfiber in breathability and the cooling effect, but comfortability is where microfiber has cotton beat. Its texture, weave and its denier size and heat retention make it a much more comfortable option that cotton. Plus it is certainly a lot more cheaper than actual cotton, which is yet another load off the mind of the person buying this stuff. 

What are Microfiber Sheets Made Of?

Microfiber entails in it two synthetic fibers, which are woven together. These include (primarily) polyester and polyamide, which are also synthetic themselves. These two fibres, along with a myriad of other fibers and materials used to make sheets from the weave, constitute what is commonly called microfiber. Strands of treated cotton may also be used to make the microfiber sheets much more soft, easy to touch and more heat resistant and moisture resistant. 

Microfiber Sheets- Do They Make You Sweat?

Yes, they do. As we’ve already talked about it, heat retention, when compared within cotton and microfiber, is the strong suit of microfiber sheets. This means that these sheets are much better at retaining and trapping heat, making them an excellent choice for usage in winters and fall season.

However, reverse the same equation and suddenly, you want to throw them out of the house. Because they are better at trapping heat, microfiber sheets are not ideal for summers, and can cause you to sweat out too much. Even in the fall season, people who don’t like to be too warm in bed complain of microfiber’s tendency to make a person sweat out. So, yes, microfiber sheets do make you sweat.

Are Microfiber Sheets Hot – Pros and cons

Both have their own sets of pros and cons, which allow for a better understanding of the two materials, and can help with the selection of materials for various uses.

Cotton- Pros: 

  • More luxurious
  • Natural and organic
  • Durable, requires less maintenance
  • Breathable, cool and moisture resistant 


  • Expensive than microfiber

Microfiber- Pros

  • Softer and more lightweight
  • Requires less maintenance
  • More durable than cotton


  • Moisture absorbent
  • More heat retention
  • Generates static


Again, its all down to personal preferences. People like cotton because it is natural and allows for a much more cooler nights sleep. Microfibers on the other hand, are preferred because they are much more durable, cost less than cotton and trap more heat and are therefore preferred for winters and fall season. Pick your choose and go with it.

is Microfiber Breathable

No, microfiber is not a breathable material. If breathability is what you’re looking for, you should go with cotton as it is a much lighter and breathable material. 

Is Microfiber Sheets Good For Skin?

microfibers and synthetic materials, and may not be good for people with allergies to synthetic materials. Furthermore, cotton-based sheets are advised for usage as they are anti-allergic and are considered more healthy than their synthetics-based cousins.
