Key features

• •🌡️ COOLING & BREATHABLE MICROFIBER SHEETS: 1800 series double-brushed microfiber fabric is designed to wick moisture and promote airflow throughout the night. Lightweight construction helps regulate body temperature — suitable for hot sleepers and warm climates. Machine wash cold, tumble dry low for easy care.
• •✅ OEKO-TEX CERTIFIED — INDEPENDENTLY TESTED SAFE: Every thread certified free from harmful chemicals, dyes, and irritating finishes. Not just "hypoallergenic" marketing — third-party verified clean. Mueller's queen sheet set is safe for sensitive skin, children's rooms, and allergy-prone sleepers. When competitors skip certification, Mueller passes it. Sleep clean, breathe easy, wash with confidence.
• •🏨 6 PIECES FOR THE PRICE OF 4: Includes 1 Flat Sheet (90"×102"), 1 Fitted Sheet (60"×80"), and 4 Pillowcases (20"×30"). Two additional pillowcases provide a spare set — practical for couples, guest rooms, and quick changes between wash cycles. All pieces crafted from matching double-brushed microfiber for a consistent look and feel.
• •💎 GETS SOFTER WITH EVERY WASH — NOT WORSE: The #1 complaint about 1800 series sheets? Pilling, thinning, and falling apart after a few washes. Mueller's double-brushed anti-pill microfiber is built differently. Silky from night one, even softer by wash 50. Wrinkle-resistant finish comes out of the dryer looking crisp — no ironing, no effort, no regrets.
• •📐 STAYS PUT ALL NIGHT — GUARANTEED FIT: Thin elastic that pops off by morning is the most common complaint in this category. Mueller's deep-pocket fitted sheet uses reinforced all-around elastic to grip mattresses up to 16" — confirmed, not just claimed. No midnight re-tucking. No popping corners. Machine wash cold, tumble dry low. Back to perfect in one cycle.
