Casper Sateen Sheets Review

If you love the feel of a smooth, polished bed, sateen sheets are hard to resist. In this Casper sheets review, we take a close look at the Casper sateen sheet set: 100% cotton bed sheets with a silky smooth sateen weave, a subtle sheen and a 450 thread count. This Casper sheets review covers sizes and prices, materials, thread count, colours, breathability, fit, care and shipping, so you can decide whether this Casper sheet set is right for your bed.

About the Casper Sateen Sheets

Casper is best known for the Casper mattress, a regular on lists of the best mattresses in Canada, but its bedding line has become a big part of the brand, and the sateen sheet set is its most luxurious cotton option. Casper sheets come in three main styles in Canada: crisp cotton percale sheets, smooth cotton sateen sheets and TENCEL Lyocell sheets. The sateen sheet set sits in the middle, with a buttery smooth, soft feel that's more polished than percale but still made from natural cotton.

What sets sateen sheets apart from percale sheets is the weave. The percale weave is a simple one-over-one-under pattern, while sateen floats several threads over a single thread, usually in a three- or four-over-one pattern. That creates more exposed thread on the surface, which gives sateen its silky smooth hand and its soft, gentle sheen. It also creates a denser fabric that drapes closely over your body rather than standing crisp like percale.

The result is a Casper sheet set designed for people who prefer sheets that feel luxurious and cozy. Casper says its sateen sheets are naturally wrinkle-resistant and get softer with every wash, so they look neat on the bed with little effort. The fitted sheet has deep pockets and four corner straps to stay in place, and like all Casper sheets, the set is OEKO-TEX certified.

The trade-off is warmth. Because the weave is tighter and heavier than percale, it holds more body heat. That makes these sheets a great fit for cold sleepers, cooler climates and the winter months, but hot sleepers may prefer Casper's percale sheets, which are lighter and more breathable.

If you already sleep on a Casper mattress, these high quality sheets are an easy match. They fit most mattresses from other brands just as well, so you don't need a Casper bed to enjoy them.

Casper Sateen Sheets: Sizes and Prices

The Casper sateen sheet set comes in six sizes: Twin, Twin XL, Full, Queen, King, California King. Each Twin and Twin XL sheet set includes one pillowcase, and each Full, Queen, King, California King sheet set includes two pillowcases.

*Prices accurate as of November 2026.

Every Casper sheet set includes one fitted sheet, one flat sheet (also called a top sheet) and matching pillowcases, so a Queen sheet set gives you two pillowcases for a standard bed setup. If you need extra pillowcases, Casper sells a matching Pillowcase Set separately.

A few sizing notes:

• Twin and Twin XL: Both Casper sheet set sizes cost $149. Twin XL sheets are longer than Twin sheets, so they're the right pick for dorm beds, adjustable bases and taller sleepers.
• Full and Queen: The Full sheet set costs $189 and the Queen sheet set costs $199, a small difference for the extra width.
• King and California King: Both the King and California King sheet set cost $249. A California King is longer and narrower than a standard King, so be sure to match the sheet size to your mattress.

At $149 to $249, the Casper sateen sheets cost about $20 to $40 more than Casper's percale sheets, depending on the size. That premium over the percale sheets reflects the higher thread count and denser weave. Compared with many luxury sheets in Canada, though, the sateen sheets cost far less, which makes them an accessible way to get a luxe, hotel-style bed.

Materials and Construction

The Casper sateen sheets are made with a simple, high quality material list:

• 100% cotton: Cotton is a natural, breathable fibre that feels soft against your skin and absorbs moisture better than synthetic fabrics like polyester. That makes cotton sheets more comfortable than most microfibre alternatives, and Casper's sateen feels smoother than most cotton sheets.
• Sateen weave: The three- or four-over-one weave gives the fabric a silky smooth surface, a subtle sheen and a fluid drape. It also helps the sheets resist wrinkles.
• OEKO-TEX certified: All Casper sheets are OEKO-TEX certified, meaning they've been tested for harmful substances. That's reassuring for anyone with sensitive skin.

Together, these features make the Casper sateen sheets feel more luxurious than traditional sheets and other sheets at this price. Casper sheets feel substantial without being stiff, thanks to high quality cotton and a dense weave. Casper says the cotton gets softer with every wash, so the sheets should feel even better after a few weeks of use.

The main drawback of the same material and weave that make sateen so soft is breathability, compared with other sheets made from breathable fabrics. A denser fabric traps more heat than percale, so these aren't the most breathable sheets in Casper's lineup. Hot sleepers may want to compare them with other breathable fabrics, like percale or TENCEL, before buying.

Thread Count

The Casper sateen sheets have a 450 thread count. That thread count is higher than Casper's percale sheets, and it's a big part of why the sateen set feels so smooth.

Thread count refers to the number of threads woven into one square inch of fabric, but it's not a straightforward measure of quality, especially across different materials. Factors like yarn thickness, weave, fibre type and finishing process all play a big role.

For example, Casper's cotton sateen and TENCEL Lyocell bedding both feature a sateen weave, but their ideal thread counts are different. Cotton relies on a higher thread count to achieve its silky smooth feel. Meanwhile, TENCEL Lyocell is naturally soft, breathable and moisture wicking, even at lower thread counts. In fact, packing too many threads into TENCEL can actually reduce its airflow and performance.

In short, thread count isn't always apples to apples. Fibre quality and finishing matter more.

That's also why you'll see a different thread count for each type of sheet. Percale sheets usually perform best between 200 and 400 threads per square inch, since lower thread counts keep the fabric light and airy. Sateen sheets often have a higher thread count, since the extra threads create a denser, smoother surface. A higher thread count isn't automatically better, though. Many budget sheets advertise a thread count of 1,000 or more by using thin, twisted threads. The result is often thin sheets that feel rough and wear out faster than cotton sheets with a moderate thread count.

At a 450 thread count, the Casper sateen sheets sit in the sweet spot for cotton sateen. They're dense enough to feel smooth and substantial, but not so dense that they feel heavy or stiff.

Colour, Design & Pattern Options

The Casper sateen sheets come in four solid colours:

• White: A classic, crisp hotel look that matches any duvet cover.
• Grey: A soft neutral that hides everyday wear.
• Indigo: A deep blue that adds rich colour to your bed.
• Oat: A warm, earthy neutral that pairs well with natural textures.

There are no prints, patterns or bright colors, so the set suits anyone who prefers a calm, classic look. The subtle sheen of the weave makes all four colours look richer than they would on a matte fabric like percale. For a coordinated bed, Casper also sells a Sateen Duvet Cover to complete your sateen set, so you can match your sheets and duvet cover in the same shade or pair a neutral duvet cover with Indigo sheets for contrast. A White duvet cover with Oat sheets, a Grey duvet cover with White sheets or an Indigo duvet cover with Oat sheets makes an easy, layered look, and any Casper duvet cover in the same material will match the sheen. Not every colour is always in stock in every size, so check availability for your size before you order Casper sheets.

Breathability

Breathability is where the Casper sateen sheets are weakest. The tight weave and 450 thread count create a dense fabric that holds more warmth than percale sheets. That's great on a cold night, but if you sleep hot or deal with night sweats, you may find these sheets a bit too warm in summer.

That said, the sheets are still 100% cotton, which absorbs moisture and allows some airflow. These cotton sheets will feel cooler than polyester or microfibre sheets, and many people find them comfortable year-round in a cool bedroom.

If you sleep hot, Casper's percale sheets are the better choice. The one-over-one-under percale weave is lighter and more open, so it allows more airflow and has a crisp feel that stays cool against the skin. Many people consider percale sheets the best of Casper's cotton cooling sheets, and they're one of the most popular cooling sheets for hot sleepers in Canada. Casper's TENCEL Lyocell sheets are another option for hot sleepers, since TENCEL is naturally moisture wicking.

In short, a sateen set is best for people who sleep cool and prefer sheets that feel cozy and smooth, while percale sheets are best for people who sleep hot and want breathable sheets with a crisp feel.

Fit & Drape

The fitted sheet on the Casper sateen sheets has deep pockets and four corner straps. The straps anchor each corner of the fitted sheet under the mattress, which helps prevent it from slipping off or bunching up overnight, even if you toss and turn. These sheets fit thicker mattresses and mattress toppers well, though Casper doesn't list an exact pocket depth, so it's worth measuring your mattress before you buy.

The drape is where sateen sheets shine. Because the fabric is denser and smoother than percale, the fabric falls softly over your body rather than tenting, and the top sheet tucks in neatly. That gives the bed a polished, hotel-style look, and the naturally wrinkle-resistant weave means the sheets stay neat with very little effort. Sateen is also quieter than percale when you move, since the smooth surface doesn't rustle.

If you use mattress toppers, the deep pockets and corner straps help the sheets fit securely over the extra height. Overall, these sheets fit well, and fit is one of the strongest features of this Casper sheet set.

Care and Cleaning

The Casper sateen sheets are easy to care for. Casper's care instructions are simple:

• Wash before first use: Toss them in the wash on a cold, gentle cycle with similar colours before using them for the first time.
• Use non-chlorine bleach only: If you need to, use only non-chlorine bleach.
• Dry on low: To finish, dry on low heat.
• Iron if you like: You can also give them a quick warm iron if you want to smooth things out.

That's it—all Casper bed sheets are easy to care for and made to stay soft wash after wash.

A few extra tips will help your sateen sheets last longer:

• Machine wash cold to protect the cotton fibres and the colour.
• Avoid high heat, which can weaken cotton and dull the sateen sheen over time. Low heat is gentler on the fabric.
• Remove the sheets from the dryer promptly to keep wrinkles to a minimum.
• Rotate between two sets so each Casper sheet set gets a break between washes.

Sateen can pill if it's washed hot or dried on high heat, so following the washing instructions and the care instructions on the care label is the best way to keep these sheets looking new.

Availability, Shipping, and Returns

You can order Casper sheets online at casper.ca in Twin, Twin XL, Full, Queen, King, California King sizes, where shipping is free across most of Canada. Extra shipping fees apply to the Northwest Territories, Yukon, Nunavut and a few remote postal codes, which are shown at checkout. Casper mattresses are also sold in Sleep Country and Dormez-vous stores across Canada, so check with your local store if you'd like to see Casper sheets in person.

Casper sheets come with a 30-night sleep trial and a 1-year warranty. If the sheets aren't right for you, you can return them during the sleep trial, and return shipping is free from within Canada. Returned sheets must be in donatable condition, free of stains, tears and odours, and refunds go back to your original payment method. The 1-year warranty covers manufacturing defects.

The 30-night sleep trial on Casper sheets is shorter than some bedding brands offer, so it's worth sleeping on your new sheets right away to make sure you like them before the sleep trial ends. Keep your receipt and the care instructions handy in case you need to start a return during the sleep trial.

Should You Buy the Casper Sateen Sheets?

To wrap up this Casper sheets review: if you sleep cool and love a smooth, luxurious bed, the Casper sateen sheets are excellent sheets at a fair price. The 100% cotton sateen weave is silky smooth, the 450 thread count gives the fabric a substantial, high quality feel, and the sheets get softer with every wash. The deep pockets and corner straps keep the fitted sheet in place, and the OEKO-TEX certification is a nice bonus. At $149 to $249, these sheets cost far less than many luxury sheets in Canada.

They aren't for everyone. If you sleep hot, the denser weave may feel too warm, and Casper's percale sheets are the better fit. The colour range is limited to four neutrals, and the 30-night sleep trial is on the short side. But for anyone who wants high quality sheets with a soft feel and a polished look, this Casper sheet set is one of the best sheets in its price range, and Casper sheets in general are a reliable choice.
