Coreeky Cotton Muslin Bassinet Fitted Sheets 3-Pack — 4" Deep Pocket, 360° Elastic for Standard & Thick Mattresses

Coreeky 3 Pack Cotton Muslin Baby Bassinet Fitted Sheets are ultra-soft, breathable fitted sheets designed to snugly fit standard and thicker bassinet mattresses with a 360° elastic pocket.

These muslin bassinet sheets combine a lightweight, open-weave cotton with a deep 4-inch pocket and full-encased elastic to create a secure, comfortable sleeping surface for newborns. The set of three gives parents dependable backups for quick changes, while the fabric becomes softer over repeated washes. The sheets are made from 100% muslin cotton and crafted to fit common bassinet mattress shapes, including hourglass, oval, and rectangular designs.

How do these sheets keep my baby comfortable through the night?

The muslin weave is loose enough to promote airflow yet soft enough for delicate skin, helping regulate temperature without heavy layers. As a natural fiber, cotton wicks moisture and breathes better than many synthetics. This makes the Coreeky sheets particularly suitable for layering in different room temperatures.

• 100% muslin cotton for breathable comfort
• Open-weave structure improves air circulation
• Lightweight fabric reduces risk of overheating
• Gets softer after each wash for ongoing comfort

Will these fitted sheets stay in place on my bassinet mattress?

Yes — each sheet has an encased 360° elastic band and a deep 4-inch pocket to hold the material securely around standard and thicker bassinet mattresses. The design minimizes shifting and reduces the need for constant re-tucking, keeping the sleep surface smooth and safe as your baby moves.

• Encased elastic wraps the entire mattress edge
• 4-inch deep pocket fits thicker mattress profiles
• Snug, wrinkle-resistant fit for uninterrupted sleep
• Compatible with hourglass, oval, and rectangular shapes

How easy are these sheets to care for during daily use?

Coreeky muslin sheets were designed for busy parents: they’re machine washable, quick-drying, and resist fading and noticeable shrinking. The fabric remains soft and more comfortable after repeated laundering, so you can keep a fresh sheet on hand without extra maintenance headaches.

• Machine washable and fast to dry
• Retains color and fit wash after wash
• Becomes softer with repeated laundering
• Three-pack gives ready-to-use spares between washes

What mattress shapes and sizes are these sheets suitable for?

These fitted sheets are made to work with a wide variety of bassinets and bedside sleepers. The generous pocket depth accommodates taller mattresses while the stretch of the elastic helps conform to hourglass, oval, and rectangular mattress profiles commonly used in bedside sleepers and standalone bassinets.

• Fits standard bassinet mattresses including hourglass shapes
• Oval and rectangular mattress compatibility
• Designed for standard and thicker mattress heights up to the 4" pocket depth
• Works well on bedside sleepers and standalone bassinets
