These Sleep Philosophy Cozy Flannel Sheets are a 100% cotton, ultra-soft four-piece full sheet set designed to deliver warm, breathable comfort for cooler nights.

Soft, brushed cotton flannel brings a classic, cozy feel to your bed without extra bulk. This full sheet set includes a flat sheet, a fitted sheet with a 12" deep pocket, and two standard pillowcases, all OEKO-TEX certified to confirm they’re free from harmful substances.

How warm and soft are these flannel sheets for winter bedding?

The brushed 100% cotton flannel surface traps gentle warmth while remaining breathable, so you get cozy insulation without overheating. The kilometer-soft finish feels plush against skin and becomes softer after each wash, offering long-lasting comfort.

• 100% cotton flannel with a brushed nap for softness
• Designed to provide warmth without blocking airflow
• Gets softer over successive washes
• OEKO-TEX certified to reduce exposure to harmful substances

Will the fitted sheet stay on my mattress all night?

The fitted sheet features an all-elastic edge and a 12" deep pocket to fit mattresses up to 12" tall and stay secure during use. The elastic runs continuously around the perimeter for a snug fit that resists shifting when you move in bed.

• All-elastic fitted sheet for a secure hold
• 12" deep pocket fits mattresses up to 12" high
• Elastic around perimeter reduces slipping and bunching

How do I care for these sheets to keep them soft and reduce lint?

Machine wash cold and tumble dry on low to maintain the flannel’s nap and color. Lint is a natural result of the brushing process; adding a half-cup of white vinegar in the first few washes helps loosen fibers and reduce shedding over time.

• Machine wash cold, tumble dry low
• Avoid bleach to protect fibers and prints
• Add 1/2 cup vinegar in early washes to reduce lint
• Shedding will subside after several wash cycles
