Cottingon 4 Piece Extra Long Staple Egyptian Cotton Sheets - Split

In this review of the Cottingon 4 Piece Sheets the bottom line is clear: these are a strong option for owners of adjustable or split-top king mattresses who want soft, breathable cotton that stays put. The set is 100% Extra Long Staple cotton with OEKO-TEX certification, and the review found the fabric becomes noticeably softer after a couple washes while the extra-wide 360-degree elastic and split-top fitted piece keep each side secure during movement. For campers, RV bunks and Sleep Number or Flex Top beds the tailored fit and color choices are the standout reason to buy.

Key Features

• Pure materials: The 100% Extra Long Staple Egyptian cotton provides breathable comfort and a smooth hand that improves with washing.
• OEKO-TEX certified: Fabric tested for harmful substances gives peace of mind about safety and chemical exposure.
• Split-top design: The half split fitted sheet allows independent movement for adjustable or split king mattresses without pulling the other side.
• Deep fit and strong elastic: Full 360-degree extra-wide elastic secures the fitted sheet on mattresses up to 16 in deep for a snug, no-shift fit.
• Complete set: Includes two pillowcases, one oversized flat sheet and one half-split fitted sheet for a ready-to-use bed configuration.
• Easy care: Machine washable in cold or lukewarm water and tumble dry low; cotton softens after a few washes for improved feel.

Who It's For

These sheets are aimed at people who sleep on adjustable beds such as Sleep Number, Flex Top King or split king configurations, and anyone with a deeper mattress up to 16 in. The split-top fitted sheet is especially useful for couples who adjust firmness or position independently at night.

Shoppers who prioritize a crisp percale or wrinkle-resistant synthetic blend should look elsewhere, as this is a pure long-staple cotton set that tends to soften and show normal cotton characteristics over time. Buyers seeking very-high thread count silkiness beyond what typical Egyptian cotton sheets provide may prefer a different luxury weave.
