Extra Deep King Sheet Set - 6 Piece Cooling & Breathable Sheets

In this review of the Extra Deep King Sheet Set the bottom line is simple: these sheets are built for very deep mattresses and anyone who needs fitted bedding that stays put. The reviewer found the set especially useful for mattress with toppers and pillow top constructions because the fitted sheet stretches around pockets up to 24 in deep, and the microfiber weave delivers a noticeably soft, breathable feel. If secure fit and softness are top priorities, this set is worth considering.

Key Features

• Extra deep fitted sheet: The fitted sheet stretches to fit pockets of 18, 20, 21, 22 and 24 in, so it tucks securely around very tall mattresses and mattress toppers.
• Six piece set: Includes one flat sheet, one fitted sheet and four oversized pillowcases with secure enclosures for a complete king bedding setup.
• Designed for pillow top mattresses: Suited for mattresses with a 3 in or 4 in topper, memory foam toppers or thick mattress pads without coming loose.
• Soft microfiber: The sheets use a soft microfiber that feels lighter and smoother than many cotton sets while remaining breathable for regular use.
• Extra deep pockets with elastic: Elastic around the fitted sheet provides stretch and a snug tug that helps the sheet stay in place overnight.

Who It's For

This set is ideal for owners of extra tall or oversized king mattresses, including those with memory foam toppers, pillow top layers or thick mattress pads who need a fitted sheet that will not pop off during the night. It also suits sleepers who prefer a very soft, microfiber hand rather than a crisp cotton feel.

Shoppers who insist on natural fibers or want the textured crispness of percale cotton should look elsewhere, since these are microfiber sheets with a smoother, softer finish that differs from cotton. Also, if pocket depth under 18 in is the only requirement, a standard deep pocket set may be a more compact option.

Pros & Cons

Pros

• Very deep pockets fit mattresses and toppers up to 24 in, eliminating constant re-tucking.
• Comes as a full 6 piece set with four oversized pillowcases that close securely.
• Microfiber surface is exceptionally soft and comfortable to the touch.

Cons

• Microfiber feel is not the same as cotton, so shoppers expecting a crisp cotton texture may be disappointed.
