10 Best Split King Sheets For Sleep Number Bed 2025 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 LANE LINEN Split King Sheets are a top choice for those with adjustable beds, particularly for their luxurious comfort and practical design.

The set is specifically designed for split king beds, with two fitted sheets that fit mattresses up to 17 inches deep, ensuring a snug and secure fit without slipping off during adjustments.

One of the standout features is the durability of the fabric, which uses a two-ply yarn method to maintain its luxurious feel over time. Maintaining these sheets is also straightforward, as they are machine washable and can be dried on a low heat setting, making them convenient for everyday use. Additionally, the elegant French Blue color can easily complement various bedroom decors, adding a touch of sophistication.

There are a few considerations to keep in mind. While the sheets are luxurious, the high thread count may not appeal to everyone, as some users prefer lighter fabrics. There’s also a slight variance in thread count that may arise from manufacturing processes, which could be a concern for those seeking absolute consistency. Despite these minor drawbacks, the sheets are ideal for anyone looking for a premium sleeping experience on a split king adjustable bed, combining style, comfort, and practicality.

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.
