10 Best Split King Sheets For Sleep Number Bed 2026 in the United States

The Split King Size 5 Piece Sheet Set from CGK Unlimited is made from high-quality brushed microfiber, which makes it very soft and lightweight. This material choice, paired with a thread count of 200, helps ensure breathability and a cool sleeping experience. The sheets' wrinkle-free property is a convenient plus for those who prefer low maintenance.

The set includes two fitted sheets, one flat sheet, and two pillowcases, making it suitable for split king beds and providing good value for families. Each fitted sheet has deep pockets, accommodating mattresses up to 16 inches, ensuring a snug fit on most modern beds, including the Sleep Number beds often known for their size variability.

The beige stripes design adds a touch of elegance, fitting well with various bedroom decors. However, the polyester material, while soft and breathable, may not appeal to those who prefer natural fibers like cotton. Additionally, while the thread count is adequate for comfort, it may not provide the same luxurious feel as higher thread count sheets. This set is a reliable and cost-effective choice for families looking for comfort and ease of care in their bedding.

The Split King Sheets from California Design Den are a notable choice for anyone with an adjustable Sleep Number bed. Made from 100% cotton and boasting a 400-thread count in a soft sateen finish, these sheets are designed to provide comfort and a luxurious feel. Their cooling properties make them suitable for year-round use, effectively managing temperature to enhance sleep quality. The sheets include two Twin XL fitted sheets with deep pockets, fitting mattresses from 8 to 15 inches deep, and a top sheet, all secured with high-quality elastic that remains snug without bunching. The head and foot indicators simplify bed-making, making it user-friendly.

On the plus side, these sheets have been recognized with the Good Housekeeping 2023 Best Bedding Award, which speaks to their quality and performance. They are also machine washable, making maintenance easy; they resist wrinkling and fading, ensuring they remain looking fresh for years.

The breathable nature of cotton is a strong advantage, particularly for individuals sensitive to synthetic materials. The Oeko-Tex certification assures users that these sheets are free from harmful substances, promoting a healthier sleep environment.

The California Design Den Split King Sheets Set offers a luxurious and comfortable choice for adjustable beds, featuring 100% cotton with a high 800 thread count for a soft, smooth feel.

The company’s dedication to quality and customer support, along with its charitable initiatives, adds a positive value to the purchase. Potential buyers should note the higher price point associated with high thread count cotton sheets. While the elasticity and fit are designed to accommodate a range of mattress depths, some users with very thick or custom-sized mattresses may still need to verify compatibility. The cooling feature is beneficial for temperature regulation, but individual experiences may vary based on personal heat preferences.
