Mellanni Ultra Soft King Sheet Set, Navy Blue — 4-Piece Deep-Pocket Microfiber, Breathable

The Mellanni Iconic 4-piece Ultra Soft King Sheet Set in Navy Blue is a deep-pocket microfiber bedding set designed to deliver a cool, hotel-like feel and long-lasting durability.

This king-size bundle includes a deep-pocket fitted sheet, an oversized flat sheet, and two standard pillowcases—each made from Mellanni's double-brushed microfiber for a silky touch. Independently tested for breathability and built to resist wear, the set combines softness with practical performance so you can get comfortable without frequent replacements or constant upkeep.

How does this set help me sleep cooler at night?

The fabric is engineered to move heat and moisture away from your skin rather than trapping it, which helps you feel more comfortable as you fall asleep and stay asleep. Third-party labs have evaluated the sheets' airflow and rated them highly for breathability.

• Double-brushed microfiber for a lightweight, airy handfeel
• Laboratory-tested breathability by accredited facilities
• Fabric lets heat and moisture pass through instead of holding them

Will these sheets fit my thick mattress and stay in place?

The fitted sheet is cut with deep 21-inch pockets and features sewn-in elastic that hugs the mattress securely. This design minimizes slipping and bunching, keeping the bed neat even with movement from sleepers or pets.

• Fitted sheet fits mattresses up to 21" deep
• All-around sewn-in elastic for a snug hold
• Generous flat sheet sizing for full tuck-in coverage

How durable and low-maintenance are these sheets?

The textile was lab-tested to exceed standard industry wear and tear thresholds, showing strong resistance to abrasion, tearing, and pilling. They require simple care—machine wash cold and tumble dry low—so they keep a smooth appearance wash after wash without significant shrinkage.

• High abrasion and tear resistance from independent testing
• Minimal pilling and near-zero shrinkage with normal washing
• Machine washable for easy home care

Are these sheets safe and chemically tested?

The set carries OEKO-TEX STANDARD 100 certification, meaning the materials were screened for a wide range of harmful substances. This gives added assurance that the textiles meet recognized safety standards suitable for family use.

• OEKO-TEX STANDARD 100 certified by Hohenstein
• Independent testing across multiple labs for quality benchmarks
• Manufactured components screened for harmful substances

Who is this for: The Mellanni Iconic King sheet set is aimed at sleepers who want a soft, breathable, and low-maintenance bedding option with a hotel-inspired feel. It’s well suited to families, shared bedrooms, and anyone with a deep mattress who values durability and easy care. If you want dependable color retention, a secure fit, and third-party-tested performance in a navy-blue finish, this set is designed for those priorities.
