In the past, thread count was a measure of quality—the higher the thread count, the better the quality. However, that simply isn't true anymore. High thread counts can certainly make for better, more comfortable sheets, but the quality of the thread matters more than the number. In fact, a better-quality fiber with a lower thread count will feel softer and stand up to washing better than a lower-quality fiber with a higher thread count. Here's what you pay for when you're buying sheets.


Cotton-polyester blend sheets are wrinkle-resistant, durable (polyester lasts longer than cotton), and relatively inexpensive (up to half the cost of all cotton). But if you're looking for cooling sheets with a soft feel, nothing beats 100% cotton. You'll rarely wake up clammy on cotton sheets, since the fiber wicks moisture away from your skin. It's also the ideal material for flannel sheets because it can provide warmth without overheating. And cotton sheets are less likely to stain than polyester blends; a water-loving fiber, cotton releases dirt easily when wet.

All types of cotton share these wonderful traits, but long-staple (or long-fiber) cotton makes for a noticeably softer sheet, and the surface won't pill and lint like one woven from shorter fibers. The words "Egyptian long-staple," "pima," and "Supima" all denote high-quality long fibers. A great alternative to cotton sheets are soft, cooling eucalyptus sheets, which also have moisture-wicking properties.


The weave affects the way a sheet feels, the way it looks, its longevity, and its price. Basic plain weaves, which are woven from an equal number of vertical and horizontal yarns, are the least expensive and may not rate a mention on the label. Percale sheets have upscale plain weave with a thread count of 180 or higher and are known for their longevity and crisp feel.

Sateen weaves have more vertical than horizontal yarns. The higher proportion of vertical threads in sateen sheets results in an extremely soft fabric, but one that is more apt to pill and tear than a plain weave. Intricate weaves (such as jacquards and damasks) feel textured, with a pattern alternating from satiny soft to coarse and nubby. They can be as durable as plain weaves, but they are made on special looms and are considerably more expensive.


Most sheets are treated with chemicals (including chlorine, formaldehyde, and silicon) to keep them from shrinking, losing their shape, and wrinkling. Some are treated with alkalis to produce a sheen.

A handful of manufacturers offer pure-finish sheets, meaning that no chemicals were used or that all traces of chemicals used during manufacturing have been removed. You'll have a harder time keeping these sheets wrinkle-free, but it may be worth it if you suffer from allergies or chemical sensitivities. (Pure-finish sheets are available from Garnet Hill,


Patterns and colors are usually applied to sheets after they're woven, which means the sheets may feel stiff until you've washed them a few times. The softest (and most expensive) colored or patterned sheets, including jacquard weaves, are made of yarn-dyed fabrics, woven from colored yarns.

Thread Count

There isn't really a best thread count for sheets. Depending on budget, aim for a thread count between 400 and 1,000.

The highest thread count you should look for is 1,000. Anything above that number is unnecessary and often lower quality. This is because manufacturers use thinner cotton to cram in as many threads as possible, increasing the ply or the number of single threads twisted together.

Sheets that are 800 thread count are almost always double-ply, meaning they are twice as thick as 400 thread count sheets. Double-ply sheets are thicker and more durable, so they tend to last longer, justifying higher prices. They are also ideal if you sleep with pets because they're better at resisting pet hair. Another advantage of 800 thread count sheets is that they allow the body to retain more heat.

A thread count of 600 is the highest possible for single ply sheets. These sheets tend to be less expensive than 800 thread count. While comparably soft, they are often less durable. However, they are better at keeping the body cooler during the warmer months.

While 400 thread count sheets are the minimum you should look for, that doesn't necessarily mean that they're low quality. In fact, 400 thread count sheets made of premium quality material can feel as soft as higher thread count sheets, possibly even softer. In fact, some of the best bamboo sheets range from 300 to 350 thread count. Long staple cotton is an ideal fiber for sheets, but particularly for lower thread counts.
