Cottingon 4 Piece Split King Sheets - Soft 100% Egyptian Cotton

In this review the Cottingon 4 Piece Full Sheets set is recommended for anyone who needs a split-top bed set that fits adjustable or Sleep Number style mattresses and values breathable, soft fabric. The biggest reason to buy is the set's combination of 100% extra long staple Egyptian cotton comfort and a practical half-split fitted sheet designed to move with adjustable bed tops without coming loose. It is a thoughtful choice for couples using a split king configuration or for RV and camper owners who need deep-pocket, flexible fit sheets.

Key Features

• Premium cotton fabric: OEKO-TEX certified 100% extra long staple Egyptian cotton provides softness and breathability that improves with washing.
• Split-top design: The half split fitted sheet lets each side of an adjustable or split king mattress move independently without pulling the sheet off.
• Deep pocket fit: Full 360 elastic and a design that fits up to 16 in deep mattresses keeps the sheets snug on adjustable and RV bunk beds.
• Complete set for split king: Includes two pillowcases, one flat sheet, and one half split fitted sheet sized for top split king configurations and similar beds.
• Easy care: Machine wash cold or lukewarm and tumble dry low; the fabric softens with a few washes for a silkier feel.

Who It's For

The set is ideal for couples with split king or adjustable beds, owners of Sleep Number or flex top mattresses, and anyone wanting a deep-pocket sheet that stays in place on an adjustable surface. It also suits RV and camper mattresses up to 16 in deep where a flexible, well-fitting sheet is needed.

Shoppers should look elsewhere if they need a fitted sheet for a non-split standard king without split capability, or if they prefer a different fiber type such as microfiber or linen. Also, those who expect instant buttery softness may want to allow for a couple machine washes for the cotton to fully break in.

Pros & Cons

Pros

• Deep pocket and full 360 elastic keep the sheet secure on up to 16 in mattresses.

Cons

• Fabric quality impressions vary among buyers; some may find the hand feel takes a few washes to reach its best softness.
