Extra Deep King Sheet Set - 6 Piece Breathable Cooling Coral

In this review of the Extra Deep King Sheet Set the bottom line is simple: these sheets are for anyone who needs truly deep pockets and a soft, breathable sleep surface. The set stands out because the extra deep fitted sheet stretches to fit mattresses with pockets from 18 to 24 in, so the single biggest reason to buy is the secure fit on tall or pillow-top mattresses that normally cause sheet headaches.

Key Features

• Extra deep fitted sheet: The fitted sheet fits mattresses with pockets from 18 to 24 in deep, so it stays securely in place even on tall or layered beds.
• 6 piece set: Includes a flat sheet, an extra deep fitted sheet and four oversized pillowcases for full coverage and pillow protection.
• Microfiber softness: Made from soft microfiber that feels light and smooth, offering a different, softer hand than crisp cotton sheets.
• Designed for toppers: Works well with 3 in or 4 in toppers, memory foam toppers and pillow top mattresses without slipping off.
• Secure pillowcase design: Pillowcases feature secure enclosures to help keep pillows tucked in overnight.

Who It's For

This sheet set is ideal for sleepers with extra tall mattresses, layered mattress toppers or deep pillow-top beds who need a fitted sheet that will not pop off the corners. It also suits anyone who prefers the soft, slightly silky feel of microfiber rather than the crisp texture of cotton.

Shoppers who insist on a crisp cotton look or who prioritize natural fiber bedding may want to look elsewhere, since these are microfiber sheets with a softer, less structured hand. Also, those who require exact threadcount details or organic fibers should consider other options.
