Why We Chose to Carry Lusomé Cooling Sheets
The science of Xirotex technology, published clinical research, and what it means for hot sleepers
In This Article
When you walk through a Furniture Fair Sleep Center, you will find mattresses engineered for cooling, breathable protectors, and airflow-promoting pillows. But the layer closest to your skin, your sheets, plays an equally important role in sleep temperature. That is why we added Lusomé cooling cotton sheets to our bedding collection. This article explains the technology behind them, what published clinical research found, and who stands to benefit most.
Why Temperature Regulation Matters While You Sleep
Your body core temperature naturally drops as you fall asleep, reaching its lowest point during the deep stages of non-REM sleep. This temperature drop is one of the signals your body uses to initiate and maintain restorative sleep cycles. When your sleeping environment or bedding traps heat, that natural cooling process is interrupted.
The result is familiar to anyone who has ever kicked off the covers at 3 a.m.: you wake up, your sleep fragments, and you lose time in the most restorative sleep stages. Research consistently links elevated sleep temperature to reduced sleep efficiency, more nighttime awakenings, and lower overall sleep quality.
Traditional cotton sheets, while breathable, do not actively manage heat. They allow air circulation but lack any mechanism to absorb or release thermal energy. For most sleepers this is fine. But for the many adults who report some form of night sweating or overheating, passive breathability is not enough.
This is where temperature-regulating fabric technology enters the conversation, and where Lusomé's approach differs from standard moisture-wicking materials.
The Science Behind Xirotex Technology
Most cooling bedding works by wicking moisture away from the skin after you start sweating. This is a reactive approach: your body must first produce sweat, and then the fabric pulls it to the surface where it can evaporate. By the time wicking kicks in, you are already uncomfortable and your sleep may already be disrupted.
Xirotex, the technology used in all Lusomé cooling sheets, takes a different approach. It is a biobased treatment applied to the cotton fibers that is designed to absorb and store heat energy before sweating begins. Think of it as a thermal buffer: as your body temperature rises, the fabric absorbs excess heat. When conditions cool down, it releases that stored heat back.
This preventative mechanism means the fabric is working to regulate temperature continuously, not just after moisture appears. The goal is to keep your skin surface in a comfortable thermal range so your body never reaches the point of triggering a sweat response.
Xirotex is not a surface coating that washes off. The treatment is integrated into the fabric fibers, meaning the temperature-regulating function is designed to last through regular laundering.

A Brand Created to Solve a Real Problem
Lusomé was founded by Lara Smith, a Canadian entrepreneur whose motivation came from a deeply personal experience. When her sister was undergoing cancer treatment, severe night sweats became a nightly ordeal. Standard bedding and sleepwear offered no relief, and the available moisture-wicking options were synthetic, uncomfortable, and clinical in feel.
Smith set out to create bedding that combined the comfort of luxury cotton with genuine temperature regulation. After years of research and development, the result was Xirotex technology applied to long-staple cotton: a product that feels like high-end bedding but performs like performance sleepwear.

Clinical Research: What the Data Shows
Lusomé cooling sheets were evaluated in a clinical study conducted by researchers at Harvard Medical School and Mass General Brigham. The results were published in Frontiers in Sleep, a peer-reviewed journal. Here is what the data showed.
+26 minutes of additional sleep per night on average
That adds up to roughly 3 extra hours of sleep per week.
69% of participants reported improved sleep quality
A majority experienced noticeable improvement in how rested they felt.
42% reduction in night sweat severity
Participants who experienced night sweats saw meaningful reduction in symptom intensity.
33% eliminated night sweat symptoms entirely
One in three participants reported no night sweats at all after using the sheets.
"The clinical study published in Frontiers in Sleep found that participants using Lusomé sheets with Xirotex technology slept longer, reported better sleep quality, and experienced significant reduction in night sweat symptoms."
It is worth noting what this study does and does not tell us. The sample size was focused on individuals who already experienced night sweats, which means the results are most applicable to that population. The study was published in a peer-reviewed journal, which means it underwent independent scientific review. However, as with any single study, these findings should be considered alongside the broader body of sleep science rather than treated as definitive proof.
Luxury Materials: 400 Thread Count Cotton
Temperature regulation is only part of the equation. If a sheet does not feel good against your skin, you will not want to sleep on it regardless of how well it manages heat. This is where Lusomé's material choices matter.
The sheets are made from 100 percent long-staple cotton at a 400 thread count. Long-staple cotton fibers are longer than standard cotton, which produces a smoother, stronger, and more durable fabric. The 400 thread count hits a sweet spot: high enough to feel luxurious and substantial, but not so dense that it sacrifices breathability.
The sheets are designed to fit mattresses up to 16 inches deep, which accommodates most modern mattresses including pillow-top and hybrid models. Deep pocket construction with elastic all around helps keep the fitted sheet secure through tossing and turning.
What you get is a sheet that combines the hand-feel and drape of premium cotton with the functional benefit of Xirotex temperature regulation. For shoppers who want both comfort and performance, this combination is the core value proposition.

Who Is Lusomé Best For?
Lusomé cooling sheets are designed to help specific types of sleepers. Here is a straightforward look at who benefits most.
Great Fit
Hot Sleepers
If you regularly wake up overheated, throw off the covers, or sleep with a fan pointed directly at you, Lusomé's preventative heat absorption approach addresses the problem before it starts. See our guide on hot sleeper solutions for more strategies.
Great Fit
Perimenopause & Menopause
Night sweats and hot flashes are among the most disruptive sleep symptoms during hormonal transitions. The clinical study specifically measured night sweat severity, and 42 percent of participants saw meaningful reduction. For anyone navigating these symptoms, temperature-regulating bedding is worth considering.
Great Fit
Memory Foam & Hybrid Mattress Owners
Memory foam and many hybrid mattresses are known for heat retention. The foam conforms to your body, which is great for pressure relief but reduces airflow. If your mattress sleeps hot but you love the feel, cooling sheets add a temperature-management layer right at the skin surface. Learn more in our guide to cooling mattresses.
Consider If
Cancer Treatment Patients
Night sweats are a common side effect of many cancer treatments. Lusomé was founded specifically to address this need. While the sheets are not a medical treatment, the published clinical data suggests they can help reduce symptom severity. Always consult with your care team about sleep comfort during treatment.
Are Lusomé Cooling Sheets Worth It?
At Furniture Fair, we evaluate every bedding product we carry against a simple question: does it solve a real problem for our customers better than the alternatives? For Lusomé, the answer is yes, for a specific group of sleepers.
If you sleep cool and comfortable on standard cotton sheets, Lusomé may not offer enough benefit to justify the investment. The technology is designed for people whose sleep is disrupted by heat, not for everyone.
But if you fall into the categories above, hot sleeper, menopause symptom management, or mattress heat retention, the combination of published clinical data, preventative temperature regulation, and genuine 400 thread count cotton comfort makes Lusomé a product we feel confident standing behind.
Our mattress team also recommends pairing cooling sheets with a mattress designed for airflow. If your mattress itself traps heat, sheets can only do so much. Understanding cooling mattress technology can help you address the problem at both layers.

Frequently Asked Questions About Lusomé Cooling Sheets
Xirotex is a biobased treatment embedded in the cotton fibers that is designed to absorb and store heat energy before sweating begins. As your body temperature rises, the fabric absorbs excess heat. When conditions cool, it releases that stored heat back. This is a preventative approach, unlike standard moisture-wicking which only reacts after sweat has already been produced.
They are primarily temperature-regulating, which is a different mechanism than moisture-wicking. Moisture-wicking fabrics pull sweat away from the skin after it has been produced. Xirotex technology is designed to manage heat before sweating starts, absorbing thermal energy proactively. The cotton base also provides natural breathability as a secondary benefit.
Lusomé cooling sheets are 400 thread count, made from 100 percent long-staple cotton. This thread count provides a luxurious feel and substantial drape while maintaining breathability. Long-staple cotton fibers produce a smoother, stronger fabric than standard cotton, contributing to both comfort and durability.
Yes. The fitted sheet is designed to accommodate mattresses up to 16 inches deep. This covers most modern mattresses including pillow-top, hybrid, and many memory foam models. The fitted sheet features elastic all around for a secure fit that stays in place through movement during sleep.
Lusomé cooling sheets were evaluated in a clinical study published in Frontiers in Sleep, conducted by researchers at Harvard Medical School and Mass General Brigham. The study found that 42 percent of participants experienced reduced night sweat severity and 33 percent eliminated symptoms entirely. While individual results vary, the published data suggests Lusomé sheets can be an effective tool for managing night sweats during menopause. They are not a medical treatment and should be considered part of a broader approach to sleep comfort.
