Extra Deep Split King Sheet Set - 7 Piece Steel Blue - Fits 18-24in

In this review the Extra Deep Split King Sheet Set is examined for owners of tall mattresses and pillow top beds who need sheets that actually stay put. The bottom line: these are a practical, very soft microfiber set crafted specifically for extra deep pocket mattresses, and they deliver on fit and comfort. The set is not for shoppers who insist on crisp cotton feel, but for those wanting a soft, breathable microfiber option that fits mattresses with 18, 20, 21, 22 and 24in pockets and includes four pillowcases for split king arrangements.

Key Features

• Extra deep fitted sheet: Designed with stretchable elastic to fit very deep mattresses and ensure the sheet stays snug on 18 to 24in pockets.
• Split king design: Comes as a split king configuration to work with adjustable bases and separate mattress pieces while covering each side fully.
• Seven-piece set: Includes a flat sheet, two extra deep fitted sheets and four oversized pillowcases with secure enclosures for a complete bedding solution.
• Soft microfiber feel: Made from a very soft microfiber construction that feels lighter and plusher than many cotton sheets.
• Good for toppers: Built to accommodate 3in to 4in toppers, memory foam pads and pillow top mattresses without slipping off.

Who It's For

This set is ideal for sleepers with extra tall or layered mattresses such as pillow tops, memory foam toppers or mattress pads who need deep pockets that actually reach down to 18-24in. It also suits people who prefer a softer, slightly plush microfiber hand rather than the crispness of woven cotton.

Shoppers who prefer a breathable natural fiber or a crisp cotton feel may want to look elsewhere; likewise anyone needing temperature-regulating cotton-linen blends should consider alternative materials. For users prioritizing fit, softness and value, this set is a solid match.

Pros & Cons

Pros

• Microfiber fabric is exceptionally soft and comfortable compared with many cotton sheets.
