An 800-thread-count sheet set. A 1,200-thread-count sheet set. At first glance, the choice might seem obvious: more threads must mean softer, better-quality sheets, right?
Not necessarily.
Thread count is one of the easiest numbers to compare when shopping for bedding, but it doesn't tell you everything about how sheets feel, how they perform, or how long they'll last. In fact, focusing too much on that number can mean overlooking the details that matter far more.
So does thread count matter? The fiber itself, the way it's processed and woven, and the quality of the finished product all play a role.
If you’re comparing cotton, linen, or bamboo viscose, here's what separates a good night’s sleep from a sweaty one.

What Does Thread Count Actually Measure?
Thread count refers to the number of threads woven lengthwise (warp) and crosswise (weft) into one square inch of fabric. For example, a 300-thread-count sheet has approximately 300 lengthwise and crosswise threads combined within that area.
The number sounds straightforward, but there's a catch: not every manufacturer calculates it the same way. Some count the individual plies twisted together to create a single yarn, rather than counting the yarn itself. This can make the advertised thread count appear higher without making the fabric softer or stronger.
And more isn't always better. Increasing thread density doesn't automatically improve fabric quality. Depending on the fiber, yarn, and weave, a denser fabric can feel heavier or have less airflow.
In fact, Consumer Reports has found that higher thread counts don’t consistently produce better sheets. In one round of testing, its top-rated percale sheet had a thread count of just 280, beating sets that advertised far higher numbers.
The takeaway here is that thread count tells you something about construction, but it doesn’t tell you whether you’ll love sleeping on the sheets.
Why Do Sheet Brands Emphasize High Thread Counts?
Because it’s easy to understand, easy to advertise, and easy to compare.
When shopping online, you can’t reach through the screen and feel the fabric. A number like 1,000 thread count gives shoppers something tangible to compare even when it doesn’t tell the whole story.
Over time, thread count became closely associated with luxury bedding. The assumption was simple: higher number, higher quality. However, the quality of fabric is more complex than that.
A sheet’s softness, durability, and overall comfort depend on several factors working together.
So if thread count isn’t the best measure of quality, what should you look at instead?
What Makes Good Sheets? 4 Things to Look For
Thread count is only one part of fabric quality. The fiber, durability, breathability, and construction can tell you much more about what you’re bringing into your home.
1. Fiber Quality & Fabric Composition
The fiber is the foundation of any sheet. Cotton, linen, and viscose made from bamboo are all used in bedding, but they have different characteristics and manufacturing processes. Even within the same fiber category, quality can vary depending on the raw material, yarn production, and finishing.
Earthly Threads sheets are made of 100% viscose from bamboo. This is a regenerated cellulose fiber, meaning cellulose from the bamboo plant is processed and transformed into a new textile fiber—not woven directly from raw bamboo.
With regenerated fibers like bamboo viscose, factors such as yarn structure, weave, and finishing are much more useful when evaluating the finished fabric. In other words, when it comes to bamboo sheets, thread count doesn’t mean much.

2. Durability, Strength, & Pilling Resistance
A good set of sheets should feel comfortable and hold up to everyday use. Textile professionals evaluate fabric performance through measurements such as:
-
Abrasion resistance: Measures how well fabric withstands repeated rubbing and friction, such as the movement that occurs when you shift around in bed.
-
Tear strength: Measures how much force a fabric can withstand before tearing. This matters when sheets are stretched or pulled during everyday use.
-
Pilling resistance: Evaluates how well a fabric resists forming small balls of fiber on its surface after friction and repeated wear.
These measurements can tell shoppers more about durability than thread count alone. Look for brands that share testing information rather than relying on impressive numbers.
3. Breathability & Moisture Management
Your sheets do more than cover your mattress. They’re in contact with your skin throughout the night, so the way a fabric handles heat, moisture, and airflow can make a difference in your comfort and rest.
Breathability refers to how easily air moves through a fabric. Moisture management describes how a material interacts with moisture (like sweat), including how it absorbs and releases it.
These characteristics depend on fiber content, yarn structure, weave, and fabric weight. Viscose made from bamboo is valued for its smooth feel, fluid drape, and moisture absorption. Combined with an appropriate fabric construction, these qualities make it an appealing option for year-round bedding.
4. Construction Details & Fit
Sometimes, the smallest details make the biggest difference. A sheet can have a beautiful finish and feel wonderful against your skin, but if the fitted sheet constantly slips off your mattress, it can quickly become frustrating.
Before purchasing a set, pay attention to:
- Pocket depth: Check that the fitted sheet accommodates your mattress, including any mattress topper.
- Elastic: Look for secure elastic designed to help keep the fitted sheet in place.
- Seams: Well-finished seams help the sheets hold together through regular use and laundering.
-
Overall fit: Make sure the dimensions match your mattress size and height.
These aren’t necessarily the details shoppers notice first, but they’re the ones they appreciate every time they make the bed.
Why Does Sheet Longevity Matter for Sustainability?
When considering sustainable bedding, it’s easy to focus on the material alone. However, we must also think about how long the product will stay in use.
Every new set of sheets requires resources to produce, package, and transport. Choosing quality bedding and taking care of it can help you get more use out of what you already own, rather than replacing it prematurely.
According to the EPA, only about 16% of discarded towels, sheets, and pillowcases were recycled in 2018, while roughly two-thirds ended up in landfills.
Sourcing and manufacturing matter too, but buying thoughtfully, then keeping what you own in use longer is one of the simplest ways to reduce waste.
- Wash according to the manufacturer’s care instructions.
- Use recommended water temperatures and drying settings.
- Avoid excessive heat and treatments that aren’t suitable for your fabric.
- Rotate between two sheet sets to reduce constant wear.
-
Store sheets completely dry in a clean, dry space.

How Earthly Threads Approaches Sheet Quality
Understanding what goes into a textile is just as important as knowing how it feels. Earthly Threads sheets are made from 100% viscose made from bamboo, and both our sheets and pajamas carry OEKO-TEX® STANDARD 100 certification.
This independent certification involves testing textile products for harmful substances against criteria covering more than 1,000 substances. Requirements vary based on the product's intended use and level of skin contact. It isn't a guarantee that a product is chemical-free, organic, or environmentally harmless, but it offers an additional level of assurance about the tested textile.
We're also honored to have received the 2025 Newsweek Readers' Choice Award for Best Sheets.
From material composition to independent testing and customer recognition, these details give shoppers more information than a thread count ever could.

What to Look for When Buying Sheets: 5 Questions to Ask
Before choosing your next sheet set, ask:
-
What is the fabric made from, and how is the fiber processed?
-
How does it handle heat and moisture?
-
Is there evidence of how well it holds up to wear and washing?
-
Does the fitted sheet fit my mattress properly?
-
What certifications or independent testing support its claims?
These questions can help you look beyond marketing numbers and make a more informed purchase.
Choosing Sheets for Comfort and Quality
A good set of sheets should be judged by more than the number printed on its packaging. The fiber, construction, comfort, and care all contribute to the experience you’ll have night after night.
Your bed is where you begin and end each day. Shouldn't the sheets you choose be worth coming back to?
At Earthly Threads, comfort and quality come together in bedding made for everyday use. Our Luxury Bamboo Sheet Set features 100% viscose made from bamboo, a smooth sateen weave, and OEKO-TEX® STANDARD 100 certified fabric.
