The Softest Cooling Sheets You’ve Ever Slept On
The Casper SuperSoft TENCEL Sheets are made for comfort and luxury, with a high thread count and a brushed surface for extreme softness. Usually, softer sheets are a little worse at keeping you cool. However, that isn’t the case with these sheets. The soft texture doesn’t detract from these sheets’ ability to keep you cool, reduce night sweats, and maintain an even temperature throughout the night.
The soft surface is nearly matte, with enough of a sheen to look great in your bedroom. These durable sheets are available in all standard mattress sizes and four different colour options, including deep indigo and a stunning light green. These sheets are super popular with Canadians. We’ll explore why they are so well-loved.

Our Methodology
Each sleep product we review goes through hands-on testing and simulations to see how it performs for Canadians. We check the materials and overall quality, then run durability tests, wash tests, and trials with our testing teams. Because sheets need a different kind of attention than mattresses, we can focus closely on cooling, softness, and longevity. The result is a transparent, in-depth look at how the sheets hold up in real-life conditions.
Casper SuperSoft TENCEL Sheets Details
Casper’s SuperSoft TENCEL Sheets have a tight weave that results in a higher thread count. This means the sheets are softer. Usually, a higher thread count would decrease breathability, but that isn’t the case here. TENCEL Lyocell is an extremely breathable, cooling material that reduces temperatures throughout the night, even with the higher thread count.
TENCEL Lyocell is also naturally sustainable and comes from wood pulp, so eco-conscious Canadians can rest easy.

Materials
Casper’s SuperSoft TENCEL sheets are made with 100% TENCEL Lyocell. This is a material derived from wood pulp. Lyocell is sustainably sourced and gathered in all of its forms. TENCEL is often used in mattress covers and other places where a softer textile is needed. It’s extremely soft, breathable, and has strong durability that you won’t find in many other options.
It’s already soft, but the surface of these sheets is also brushed for additional softness. The result is a velvety texture that extends beyond the sheets’ surface.
Performance Test Results
Cooling
If there is a single thing that the Casper SuperSoft TENCEL sheets do well, it’s cooling. The soft, brushed surface works to wick away moisture so night sweats don’t stand a chance. The natural TENCEL Lyocell material is naturally cooling. It has much greater breathability than other materials, with a tight weave and a brushed surface for an added touch of comfort.
If you usually overheat, this sheet set is perfect for you. It expertly regulates body temperature to keep you cooler and more comfortable.
Colour Options
The Casper SuperSoft TENCEL Sheet Set comes in four colour options. You can choose White, Gray, Indigo, or Moss for the sheets set, duvet cover, and pillowcase set. Make sure you choose the same colour across of the pieces you want, including the duvet cover and pillowcase set.
Sizes
These sheets are available in all six standard mattress sizes. All four colours are available across all sizes, and availability seems consistent. Whatever size you need, there’s a good chance it’s in stock. In the table above, we listed the dimensions for the fitted sheets that come with each size. Use these dimensions against the size of your mattress to make sure that the sheets are going to fit. Available sizes are: Twin, Twin XL, Full, Queen, King, and California King.
The matching duvet cover is available in three sizes, but each of these sizes covers two different mattress sizes. Options include Twin/Twin XL, Full/Queen, and King/California King. Finally, the matching pillowcase set includes two pillowcases and is available in Standard or King.
Set Options
There are three options available in the listing for these sheets. You can select the sheet set, a matching duvet cover, or a pillowcase set. When you purchase the sheet set, the contents vary based on size. Here’s what you’ll get:
- Twin and Twin XL: 1 fitted sheet, 1 flat sheet, 1 pillowcase (standard size)
- Full, Queen, King, California King: 1 fitted sheet, 1 flat sheet, 2 pillowcases
In addition to the sheet set, you can also select the matching duvet cover or an additional pillowcase set. The pillowcase set comes with two pillowcases of your chosen size.
Sleep Trial and Warranty
Casper’s SuperSoft TENCEL Sheets come with a 30-night sleep trial. During the first month you own the sheets, you can return them at any time if you find that you don’t like them. Returns are simple and free, though some policies may vary based on a handful of different factors. Make sure that you keep the sheets in a clean, sanitary condition for best results.
When you decide to keep the sheets, you’ll have a 1-year warranty. The warranty protects against material defects, a range of issues that arise due to poor workmanship, and manufacturing issues that lead to failure or tearing during normal use.
Should You Buy The Casper SuperSoft TENCEL Sheets?
The Casper SuperSoft TENCEL Sheets are luxuriously soft. If you want sheets that feel amazing to slide into after a long day, these are the perfect choice. They don’t have the silky sheen of other sheets, though; instead, you’ll get a soft, brushed surface that feels more like flannel (without the pilling).
These sheets still have a slight sheen, but they are mostly matte. This gives them a certain look and feel that can complement any bedroom. We only wish that they were available in more colours.
Additionally, these sheets work perfectly for those who sleep hot. Though the weave is tighter here than it is for most cooling sheets, the materials make up for it with moisture-wicking and temperature-regulating properties. If you sleep hot, these sheets are a good choice.
“I haven’t had night sweats since I got these sheets. I can’t believe how soft they are and how cool they sleep.”
