Cool Bed Sets: Best Cooling Bedding for Hot Sleepers

If you have ever kicked the covers off at 2 a.m. because you felt like you were sleeping in a sauna, you already know the frustration of overheating at night. It happens to more people than you might think, and the problem often is not your mattress or your thermostat. It is your bedding. The right cool bed sets can make a genuine difference between tossing all night and waking up feeling rested.

The good news is that cooling bedding technology has come a long way. You do not need to spend a fortune, either. But you do need to know which materials actually work and which ones are just clever marketing. That is exactly what this guide covers.

What Makes a Bed Set "Cooling"?

Not every bed set that says "cooling" on the label actually keeps you cool. The term gets thrown around loosely, so it helps to understand the basic science behind why some fabrics sleep cooler than others.

Three things determine how well bedding regulates your temperature:

Breathability refers to how easily air passes through the fabric. Open weave structures like percale allow more airflow than tightly woven sateen. When air circulates through your sheets, it carries body heat away instead of trapping it against your skin.

Moisture wicking is the fabric's ability to pull sweat away from your body and spread it across a larger surface area so it evaporates faster. Bamboo and Tencel excel at this because of their fibre structure. The tiny channels within these fibres transport moisture outward, keeping the surface that touches your skin drier.

Thermal conductivity describes how quickly a material transfers heat. Linen, for example, feels cool to the touch because it conducts heat away from your body quickly. Polyester does the opposite. It insulates and holds heat close, which is great in winter but miserable in summer.

The best cooling bed sets combine all three properties. They breathe, they wick, and they conduct heat away from you. That is why material choice matters so much more than thread count or brand name when you are shopping for temperature regulation.

Best Cooling Materials Compared

Here is an honest comparison of the most common bedding materials and how they perform for temperature regulation. We are ranking these from best to worst for hot sleepers.

• Bamboo Viscose: Excellent moisture wicking, naturally breathable, and soft against the skin. Bamboo fibres have micro-gaps that promote ventilation and moisture evaporation. It sleeps about 3 degrees cooler than cotton on average. The downside is that it wrinkles easily and requires gentle washing. This is our top recommendation for most hot sleepers in Ontario's humid summers.
• Tencel (Lyocell): Made from sustainably harvested eucalyptus wood pulp, Tencel manages moisture even better than bamboo in some tests. It has a smooth, cool-to-the-touch surface and resists bacterial growth, which means less odour between washes. Slightly more durable than bamboo but can cost a bit more. A great choice if you want something that feels crisp and clean.
• Linen: The classic hot-climate fabric. Linen is extremely breathable and gets softer with every wash. It absorbs up to 20% of its weight in moisture before feeling damp. The tradeoff is that new linen feels rough, it wrinkles heavily, and quality linen bed sets tend to be the most expensive option. Best for people who like a relaxed, textured feel and do not mind the lived-in look.
• Percale Cotton: A crisp, matte-finish weave that breathes well and stays cooler than sateen cotton. Look for long-staple cotton (Egyptian or Supima) in a percale weave with a thread count between 200 and 400. Percale is widely available, easy to care for, and more affordable than bamboo or linen. It is a solid middle-ground option. Not as cool as bamboo, but noticeably better than standard cotton blends.
• Microfibre and Polyester Blends: These are the most affordable bed sets on the market, and there is a reason. Synthetic fibres do not breathe well, trap body heat, and have poor moisture-wicking properties. If you sleep hot, microfibre will make it worse regardless of what the packaging claims. Some brands add "cooling gel" finishes to polyester, but these effects wear off after a few washes. We do not recommend synthetic bedding for anyone who struggles with night sweats or overheating.

What to Look for in a Cooling Bed Set

When you are shopping for cool bed sets, these are the details that actually matter. Ignore the marketing buzzwords and focus on these specifics.

Thread Count (200 to 400 is the sweet spot): Higher is not always better when it comes to cooling. Thread counts above 400 often mean a tighter weave that restricts airflow. For cooling bed sets, you want a thread count between 200 and 400. This range gives you a fabric that is soft enough to feel luxurious but open enough to let air circulate. Anything marketed as "1,000 thread count cooling sheets" is contradicting itself.

Weave Type (Percale beats Sateen for cooling): Percale is a one-over, one-under weave that creates a crisp, breathable fabric. Sateen uses a one-under, three-over pattern that produces a silky sheen but traps more heat. If staying cool is your priority, always choose percale over sateen. Sateen looks beautiful, but it sleeps warmer.

Set Components: A standard bed set typically includes a fitted sheet, a flat sheet, and two pillowcases (or one for twin sizes). Some sets include extra pillowcases or a duvet cover. Make sure you know what is included before comparing prices. A four-piece bamboo set at $180 is a better deal than a two-piece set at $120 when you do the math per piece.

Certification and Quality: For bamboo, look for OEKO-TEX certification, which means the fabric has been tested for harmful chemicals. For Tencel, the brand name itself (owned by Lenzing AG) is a quality indicator. Generic "lyocell" can vary in quality, but genuine Tencel-branded fabric meets consistent standards.

Care Instructions: Cooling fabrics tend to be more delicate than standard cotton. Bamboo and Tencel should be washed in cold water on a gentle cycle and dried on low heat. Linen gets better with washing but should not be bleached. Check the care label before you buy, and be honest about whether you will follow the instructions.

Canadian Pricing for Cooling Bed Sets

Bedding prices in Canada tend to run higher than what you see on American websites, partly due to exchange rates and partly because of shipping. Here is a realistic breakdown of what you should expect to pay for a queen-size cooling bed set from Canadian retailers in 2025.

• Microfibre and Polyester Sets: $60 to $150 CAD. The cheapest option, but not truly cooling. These work fine for winter or for sleepers who do not run hot. If temperature regulation matters to you, save up for a better material instead of spending $80 on something that will make you sweat.
• Cotton Percale Sets: $100 to $250 CAD. A solid mid-range choice. Canadian brands like Au Lit Fine Linens and QE Home offer good percale options. Look for long-staple cotton and a thread count of 200 to 400. You can sometimes find quality percale sets on sale for under $150, which is an excellent value.
• Bamboo and Tencel Sets: $150 to $350 CAD. This is the sweet spot for cooling performance. Our Bamboo Luxe sheets fall in this range, and we have priced them to be competitive with what you would find online, with the added benefit of being able to feel the fabric before you buy. At this price point, you are getting genuinely effective temperature regulation.
• Linen Sets: $200 to $400 CAD. Premium linen bed sets from reputable brands cost more upfront, but linen lasts for years and actually improves with age. If you can afford the investment, a quality linen set will serve you for a decade or more. Just know that the first few washes will feel rougher than you expect.

A few things to keep in mind about pricing. Sales happen regularly, especially during Boxing Day, Victoria Day weekend, and Labour Day. Buying directly from a local retailer like us often means you avoid shipping costs that add $15 to $30 on top of online orders. And do not forget that you can feel and compare fabrics in person, something you simply cannot do when ordering online.
