Extra Deep Split King Sheet Set - Light Sage 7 Piece Deep Pockets

Our review of these extra deep split king sheets finds them best for sleepers with very tall mattresses or those who add thick toppers. The bottom line: the single biggest reason to buy is the extra deep fitted sheets that fit mattresses with 18 to 24 in pockets and stay in place thanks to full elastic all around. The set feels distinctly soft and breathable, tailored more for people who prefer a microfiber feel rather than crisp cotton, and it includes four oversized pillowcases so couples who use multiple pillows will appreciate the coverage.

Key Features

• Extra deep fit: The fitted split king sheets stretch to fit mattress pockets from 18 to 24 in, keeping corners secure even on very tall beds.
• 7 piece set: Includes two fitted sheets split for a king configuration, one flat sheet, and four oversized 20 x 40 in pillowcases for full pillow coverage.
• Designed for toppers: Works well with 3 in to 4 in pillow top or memory foam toppers so the sheet does not pop off during use.
• Microfiber softness: Made from a fine microfiber that delivers a softer, lightweight feel compared with typical cotton sheets.
• Secure pillowcase closure: Pillowcases feature an enclosure design to keep pillows contained through the night.

Who It's For

These sheets are ideal for owners of extra tall mattresses, such as split king configurations with deep pillow tops or added memory foam toppers, who need reliable stay-on performance. Couples who use two twin XL fitted pieces to make a split king will like the tailored fit and the four pillowcases that cover multiple sleeping setups.

Shoppers who prefer a crisp cotton hand or seek temperature-regulating natural fibers may want to look elsewhere, as these are microfiber sheets with a softer, slightly silky feel rather than a cotton crispness.
