The Truth Behind 1000 Thread Count Sheets

We all assume that a higher thread count means better quality but thread count is no guarantee of quality. When starting in 2010, we were in for a big surprise.

Green as they come

In January 2010, we were excited to be starting a new business. We wanted to sell high-quality cotton sheets, so asked Portuguese producers for 1000 thread count sheets, 2000TC if they made them.

Honestly, you could hear a pin drop.

After an awkward silence, the experts laughed (politely). They explained that if we wanted to sell high-quality bed sheets, we didn't want 1000 thread count sheets because they were considered an industry joke. In fact, a US retailer was sued over high thread count sheets in 2005, but we'll get to that later.

How can this be?

Super high thread counts are achieved using double or triple insertions, and/or by counting the invisible threads in a multi-ply yarn. Invisible threads?

Multi-ply yarns are made by twisting two or more threads together. The simplest form of multi-ply yarn is called a two-ply yarn (illustrated).

How thread count works in 1000 thread count sheets

In a two-ply yarn, each visible thread you see is made up of two invisible threads twisted together (a bit like rope). In a three-ply yarn, there are three invisible threads, and so on.

So if we weave a 333 thread count sheet from a three-ply yarn, we can advertise a thread count of 1000 (333 x 3). In reality, high thread count sheets don't use tidy mathematics like this, but this example illustrates how multi-ply yarns increase thread count.

High thread count sheets can mislead consumers

In the commercial world, thread count is calculated by counting those invisible threads in a multi-ply yarn. But in the commercial world, you're given the rest of the information to understand what you're buying - things like yarn type, cotton grade, cotton origin and weave-type.

However, in the retail world, these critical quality indicators can be hard to find. And because we as consumers equate thread count with quality, we naturally assume that the finest quality threads are used to make 1000 thread count sheets.

And now we have the main ingredients for a modern sheet recipe that (discussed here) has resulted in a class action law suit, and prompted the US Federal Trade Commission to warn the textile industry about thread count claims it considers misleading

“…we believe that consumers could be deceived or misled by the practice of stating an inflated thread count, achieved by multiplying the actual count by the number of piles within the yarn."

— US Federal Trade Commission

A controversial sheet recipe

The problem with high thread count sheets is that they take advantage of our assumption that higher thread counts are better. But a higher thread count doesn't automatically fix poor cotton or manufacturing, that's why Bed Bath & Beyond in America were sued. And this is the problem with judging sheets by thread count alone.

At this point, it's important to stress that not all 1000TC sheets are subject to criticism; it comes down to the quality. But when 1000 thread count sheets are made from the finest quality cotton like we assume, they cost NZD 1300+ a set. And when made from really great cotton, they still cost NZD 900+ a set. Really?

Basically, more threads equal more cotton, and more cotton equals higher costs. So when expensive cotton is used in a sheet recipe which consumes double or triple the cotton, you get an eye-watering price.

Hotels prioritise quality over thread count

Interestingly, hotels prioritise quality over thread count. So hotels generally use low thread count sheets (250TC). Fewer threads use less cotton, less cotton means lower costs, and this allows hotels to increase the quality for a reasonable price.

So what about high thread count sheets that don't cost NZD 900+? Compared to high quality 1000TC sheets, affordable 1000TC sheets compromise cotton quality, manufacturing, worker conditions, chemical recycling, chemical disposal etc, all to make high thread count sheets affordable.

Does it matter? That all depends on the individual, and we can't stress this enough; if you're happy with your sheets, that's all that matters to us. But if 1000 TC sheets you've purchased haven't lived up to the hype, this article attempts to explain why.

The higher the thread count, the hotter the sheet

Over the years, countless people have told us they're too hot at night. And when asked what thread count they use, they proudly state 1000TC. If you're hot at night, then 1000TC sheets are almost the worst sheets you could buy because besides synthetics, 1000TC sheets are the hottest, non-flannel sheets available.

1000TC sheets are hot for two reasons; 1) the amount of cotton in the sheet. 2) the sateen weave which while soft, doesn't breathe so traps heat.

If you're always cold at night, then high thread count sateen sheets are a great choice. But if you're hot, or sleep with a foot hanging out of bed, go for low thread count percale sheets like our classic hotel sheet. Less cotton makes them finer and the percale weave breathes properly.

A New Zealand 1000 thread count sheet

1000 thread count sheets compared to 425 thread count sheets

Left sheet: A brand new, 1000 thread count (TC) sheet, cold washed, and air dried on an indoor clothes rack. It was purchased from a chain of 'designer' and 'exclusive' New Zealand bed linen stores, retailing for around $320 for a Queen set.

Right sheet: A 435 thread count (TC) sheet from The Hotel Sheet after fives years of use in rotation with three other sheets (slept in, washed then dried every third week for five years).

In terms of straight out quality, this is an unfair comparison because the sheet on the right is better quality (so costs more). But in this instance it's relevant because we're simply using it to show what a sateen weave should look like, at any price.

To begin with, we're looking at the underside of a sateen weave, so although the ridges we can see won't directly touch your skin from the bottom sheet, they will from the top sheet.

OK, so what exactly are these ridges?

1000 thread count sheets poor manufacturing

Well, they're not particularly soft and while they improved after ironing, they didn't get much better in many areas (and we have one of those mega steam irons).

To be honest, we had no clue what was going on, so received help from a lovely textile expert who knows her stuff, and who happened to be visiting (handy that).

She said that when sheets (or any fabrics) are washed the first few times, stresses within the yarns/threads, which occur during manufacture, are relaxed. Initial stress relaxation is normal, but should be even and of minimal amount. Otherwise there is noticeable shrinkage in size and change in fabric appearance.

She suspects uneven stress on the warps and wefts (vertical and horizontal threads), and possibly inconsistent thread twist (or windings), may have caused the fabric to appear puckered and uneven after it was washed.

OK, so these ridges are probably the result of lower manufacturing quality. And in the same way that a high thread count doesn't guarantee quality cotton, it also doesn't guarantee good manufacturing.

Whatever the cause, 'exclusive' and 'designer' sheets shouldn't really do this.

Why doesn't the 1000TC sheet look finer?

1000 thread count sheets thread thickness

Some of you may have also noticed that the 1000TC sheet doesn't look finer than the 435TC sheet, if anything, it looks bulkier.

This is another reason why many feel high thread count sheets mislead consumers. We tend to think that a higher thread count translates into finer quality.

But depending on the cotton, multi-ply threads can end up thicker as the bulkiness comes from all those invisible threads which were twisted together. To see this visualised, compare the multi-ply thread (1) with the single-ply thread (2) in the illustration.

So where does this leave us?

You're going to tell us to spend more – right?

Well, cotton products in general have a horrifying churn rate (mainly due to fashion) and the Textile school at the University of Otago estimates that kiwis toss 37kg of home textiles per person, per year.

There are strong arguments for spending more but less often (as opposed to spending less, more often). One being the amount of drinking water cotton crops consume. Cotton is universally acknowledged as a thirsty crop so the more often we buy, the more drinking water we use - something we don't appreciate in a rainy nation like New Zealand.

We all know that buying quality reduces waste but it's an issue of cashflow for most of us (it's also better for retailers to get more regular sales). So this has been our challenge, could we produce a cost-effective sheet that performs better than the 1000 thread count sheets we've tested?

Well today, we’re super excited to announce that our new range will land next month. It's our take on the cool, crisp hotel sheet.

The Classic Sheet will start at just $159 NZD for a Queen half set (fitted bottom and two pillowcases) and $219 for a Queen full set (top sheet, fitted bottom and two pillowcases).

And our Egyptian Hotel Sheets start at $297 for a half set and are made from the best-of-the-best, long-staple Egyptian cotton.

As an alternative to buying from us, the best place to buy bed sheets is any company that understands cotton is more important than thread count. Look for companies that state a cotton grade such as medium-staple or long-staple cotton.

There's a difference between Percale and Sateen, especially if you prefer warmer sheets over cool and crisp hotel sheets. So stay in touch for information on how sheets are made and how different techniques effect the way sheets feel and last.

Future posts will also discuss the different types of cotton quality, threads per square inch vs threads per square 10cm and much more.
