King Size 4 Piece Cotton Flannel Sheets - Deep Pocket 16in Fit

In this review of the King Size 4 Piece Cotton Flannel Sheets, the bottom line is simple: these sheets are for anyone who wants a soft, warm bedcover without fuss. The set delivers on comfort and fit thanks to a 100% cotton double brushed flannel construction that traps warmth while remaining breathable. After several washes the fabric becomes notably plush, and the deep pocket fitted sheet is sized to stay put on mattresses up to 16in. It is an easy choice for cold-season sleepers and anyone seeking low-effort care for a cozy bed.

Key Features

• Material: Made from 100% cotton double brushed flannel at 155 GSM, giving a soft, velvety hand and steady warmth without feeling heavy.
• Fit: Fitted sheet fits mattresses up to 16in with deep pockets and stays secure through normal movement and sleep.
• Set Contents: King set includes one flat sheet (108in x 102in), one fitted sheet (78in x 80in) and two pillowcases (20in x 40in), covering standard king bedding needs.
• Thermal balance: The double brushed surface traps air and body heat while remaining breathable, making it suitable for multiple seasons.
• Care instructions: Machine wash warm and tumble dry low; drying promptly maintains fit and fabric life when bleach and fabric softeners are avoided.

Who It's For

This sheet set is ideal for people who prioritize a plush, warm sleeping surface in cooler months or who prefer a soft flannel feel year-round. It suits owners of deeper mattresses up to 16in and those who want a complete king-size coordinate without hunting separate pillowcases or specialty fitted sheets.

Those who need very lightweight summer-only bedding or require performance bedding for high-moisture activities should look elsewhere; the fabric is designed to keep warmth in, so it will feel warmer than percale or lightweight cotton weaves.
