Extra Deep Split King Sheet Set Antique White - 7 Piece Deep Fit

In this review of the Extra Deep Split King Sheet Set in Antique White, the bottom line is clear: these sheets are made for anyone with a very tall or pillow-top mattress who needs a secure, comfortable fit. The reviewer found the biggest reason to buy is the extra deep fitted sheet design that accommodates 18 to 24 in mattress pockets and stays in place thanks to stretchable elastic. The set's soft microfiber feel and four oversized pillowcases make it a practical choice for sleepers who prioritize fit and softness over crisp cotton texture.

Key Features

• Extra deep pockets: Fits mattresses with 18, 20, 21, 22 and 24 in pockets so it works on very tall mattresses and many pillow-top setups.
• Secure elastic: Stretchable elastic around the fitted sheet provides a snug tug and helps the sheet stay on all four corners during regular use.
• 7 piece configuration: Includes a fitted sheet, flat sheet and four oversized 20 x 40 in pillowcases so both sides of a split king setup are covered.
• Soft microfiber: The microfiber weave gives a super-soft, light feel that is noticeably different from crisp cotton and feels cozy against the skin.
• Good for toppers: Designed to work with 3 in and 4 in toppers, memory foam pads and pillow top mattresses without slipping off.

Who It's For

The set is ideal for owners of split king beds with extra tall mattresses, thick toppers, or double pillow-top constructions who need a deep fitted sheet that will not pop off during the night. Couples who use a split king foundation will appreciate the two fitted sheets sized to 39 x 80 in with deep 21 in pockets and the four oversized pillowcases for larger pillows.

Shoppers who prefer the crisp feel of cotton percale or who require natural fibers for temperature or allergy reasons should look elsewhere; microfiber has a notably softer, less crisp hand and a different breathability profile than cotton. Those needing fitted sheets for standard-depth mattresses may find the extra depth unnecessary.

Pros & Cons

Cons

• Microfiber feel is soft and not crisp like cotton, so it may not suit those who prefer percale texture.
