Frequently asked questions
What are the benefits of extra deep pocket sheets?
Extra deep pocket sheets are designed to fit thicker mattresses, such as those with pillow tops or mattress toppers, without slipping off. They provide a secure fit, reduce wrinkles, and ensure comfort throughout the night.
How deep should pockets be for a 25-inch mattress?
For a 25-inch mattress, look for sheets with pockets at least 22 to 24 inches deep, as some stretch accommodates the extra inch. Sheets claiming 21-inch depth may still fit with some tension, but owners often recommend 22 inches or more.
What materials are best for extra deep pocket sheets?
Microfiber and polyester blends offer excellent stretch and durability, while bamboo and TENCEL provide breathability and softness. Cotton is natural and breathable but may lack the stretch needed for very deep mattresses without special construction.
How to keep extra deep pocket sheets from slipping?
Use sheets with strong elastic all around the fitted sheet, and consider mattress straps or suspenders for additional grip. Washing sheets in cold water and drying on low can maintain elastic tension.
Do extra deep pocket sheets fit adjustable beds?
Yes, many extra deep pocket sheets fit adjustable beds, especially those made from stretchy materials like microfiber or spandex blends. Ensure the sheet has a deep enough pocket and elastic all around to accommodate mattress movement.

For the best overall performance with 25-inch mattresses, the Sleep Number True Temp Sheet Set delivers unbeatable cooling and a perfect fit.
