Casaluna Supima Percale Sheet Set
Our Casaluna Supima Percale Sheet Set delivers the crisp, cool hand feel that made percale weave a bedding classic. We source 100% long-staple Supima cotton grown exclusively in the United States for exceptional softness and durability that improves with every wash.
The tight one-yarn-over, one-yarn-under percale weave creates breathability you can feel the moment you slip between the sheets. This set includes one flat sheet, one fitted sheet with 15-inch deep pockets, and two pillowcases in standard or king size depending on your mattress dimensions.
Our matte finish resists pilling while maintaining a hotel-quality drape season after season. The natural fiber wicks moisture and regulates temperature, making this bedding casaluna supima percale sheet set ideal for warm sleepers or anyone who prefers a crisp, lightweight feel over sateen's silky finish.
Pure Supima Cotton Details

Why Supima Cotton Makes a Difference
Supima represents only 1% of cotton grown worldwide, and we use it exclusively in our percale sheet set because its extra-long staple fibers create stronger, softer fabric. Regular cotton fibers measure 22-28mm in length, while Supima fibers reach 35mm or longer, resulting in fewer joins during spinning and a smoother finished textile.
This premium fiber resists pilling, fading, and tearing far better than conventional cotton. You’ll notice the difference in durability after just a few months of weekly washing when our Supima sheets retain their crisp structure while standard cotton sheets begin showing signs of wear.

Percale Weave Construction & Feel
What Makes Percale Different
Percale refers to the tight one-over-one-under basket weave we use to construct these sheets. This weave creates a matte finish with a crisp, cool-to-the-touch hand feel that contrasts sharply with sateen’s silky smoothness. Our 200 thread count delivers the ideal balance between breathability and durability without the stiffness of higher-count percales.
The weave’s open structure allows air to circulate freely between fibers, preventing heat buildup during sleep. Hot sleepers and warm-climate residents consistently rate percale as their preferred bedding construction because moisture evaporates quickly rather than being trapped against skin.
Sizing, Fit & What's Included
Our fitted sheet features 15-inch deep pockets with elastic completely surrounding the sheet perimeter for secure grip on mattresses from 10 to 16 inches thick. This universal fit accommodates standard, pillow-top, and memory foam mattresses without bunching or corner pop-off during sleep.
Each complete set includes one fitted sheet sized to your mattress, one flat sheet with generous overhang for tucking, and two pillowcases. Twin and Twin XL sets include one standard pillowcase, while Full, Queen, King, and California King sets include two pillowcases matching the appropriate size for your bed configuration.

Supima Percale Sheet Set Questions
Percale uses a tight one-over-one-under basket weave that creates a matte, crisp finish with maximum breathability. Sateen employs a four-over-one-under weave that produces a smooth, lustrous surface with a silkier hand feel.
Percale sheets feel cooler to the touch and resist heat buildup, making them ideal for warm sleepers or climates. Sateen offers more warmth and a draped, luxurious feel preferred by those who prioritize softness over temperature regulation. Both our percale and sateen sheet sets use the same premium Supima cotton, so durability and quality remain consistent across weave types.
Our percale sheets are pre-shrunk during manufacturing to minimize dimensional changes. You may see 2-3% shrinkage after the first wash, which is normal for 100% cotton bedding.
To minimize shrinkage, always wash in cold water and tumble dry on low heat. High heat causes cotton fibers to contract more aggressively, leading to tighter weave and reduced size. Remove sheets promptly from the dryer while still slightly damp to maintain original dimensions. When cared for properly, your fitted sheet will continue to fit mattresses up to 16 inches throughout its lifespan.
Percale's crisp weave naturally wrinkles more than sateen, but most wrinkles release once sheets are placed on the bed and slept on. Remove sheets from the dryer immediately while still warm and slightly damp, then place them directly on your mattress.
If you prefer a pressed appearance, iron sheets on medium heat while they're still damp for easiest wrinkle removal. You can also hang sheets on a line to air dry, which reduces dryer wrinkles naturally. Many percale enthusiasts embrace the lived-in texture as part of the aesthetic, especially in casual or coastal bedroom styles.
Yes, our bedding casaluna supima percale sheet set is OEKO-TEX Standard 100 certified, meaning it's tested and verified free from harmful chemicals, heavy metals, and irritating substances. The 100% natural Supima cotton contains no synthetic fibers or chemical finishes that can trigger skin sensitivity.
The percale weave's breathability also benefits sensitive skin by reducing moisture buildup and friction during sleep. Cotton's natural hypoallergenic properties resist dust mites better than synthetic materials. If you have severe allergies or sensitivities, wash new sheets before first use to remove any manufacturing residue.
Our 200 thread count represents the ideal balance for percale construction. Higher thread counts in percale (above 250) create stiffer, less breathable fabric that defeats percale's purpose as a cool, crisp bedding option.
Thread count measures yarns per square inch, but weave type and fiber quality matter more for performance. Our single-ply Supima cotton yarns in a classic percale weave deliver superior durability and comfort compared to inflated thread-count sheets using multi-ply yarns or inferior cotton. Focus on fiber quality and weave construction rather than chasing high thread-count numbers.
With proper care, our Supima cotton percale sheets typically last five to seven years of regular use while maintaining their structure and softness. The long-staple Supima fibers resist pilling, tearing, and thinning significantly better than conventional cotton.
You'll notice the hand feel improving rather than degrading during the first year as the cotton softens naturally. Rotate between two sheet sets to extend lifespan by reducing wash frequency. Avoid harsh detergents, bleach, and high-heat drying, which accelerate fiber breakdown. Many customers report our percale sheets outlasting department store options by three to four years.
Absolutely. Percale's temperature-regulating properties make it suitable for all seasons. In summer, the breathable weave prevents heat buildup and wicks moisture efficiently. During winter, layer our percale sheets under warmer blankets or duvets—the crisp cotton provides a comfortable base layer that doesn't trap excess warmth when you add coverage.
Many customers prefer percale year-round because it adapts to bedroom temperature rather than adding warmth or coolness on its own. If you run very cold in winter, consider pairing percale with our flannel duvet cover or adding a thermal blanket rather than switching to sateen sheets.
