COONP King Mattress Topper — Extra-Thick Cotton Pillow-Top Pad for 21" Deep Mattresses, Breathable & Machine-Washable

COONP King Mattress Topper is an extra-thick cotton pillow-top mattress pad designed to add plush, breathable loft and secure fitted coverage to king-size mattresses up to 21" deep.

This pillow-top mattress topper from COONP layers a generous, overfilled cotton surface over an elastic deep-pocket skirt to transform a firm or worn mattress into a softer, more comfortable sleep surface. Built to be breathable, machine-washable, and easy to fit, the topper helps regulate temperature and maintain its loft after laundering. It ships compressed and rebounds with simple shake-and-dry steps so it’s ready for nights of cushioned support.

How does this topper change the feel of a firm mattress?

The COONP pillow top adds a plush layer that evens pressure and creates a cushioned sleeping plane. Fill is distributed to reduce point pressure and provide a softer initial sink without replacing the mattress.

• Extra-thick overfilled pillow-top construction for added softness.
• Supports side, back, and stomach sleeping positions evenly.
• Top surface designed to spread weight to lessen pressure spots.

Will it help keep sleepers cool through the night?

The topper’s cotton surface and ventilated design help move air and wick away moisture so sleepers feel drier and less prone to overheating than with dense foam layers.

• Breathable cotton top promotes airflow across the sleep surface.
• Moisture-wicking properties reduce clamminess from sweat.
• Suitable to layer over memory foam to reduce trapped heat.

How do I fit and secure it to a deep mattress?

COONP’s elastic deep-pocket skirt functions like a fitted sheet, gripping mattresses from 8" up to 21" deep so the topper stays flat and in place while you turn or change sleeping positions.

• Elasticized skirt wraps around mattress edges for a snug fit.
• Available sizes sized to standard mattress dimensions with an 18" skirt allowance.
• Holds securely during normal movement to prevent shifting or bunching.

What care is needed to keep the topper fluffy and clean?

The topper is machine washable and made for routine home care; laundering and low-heat tumble drying revive loft and remove body soils without professional cleaning.

• Safe for commercial or home washers; tumble dry low to restore loft.
• Shake and pat after unpacking to accelerate rebound from compression.
• Simple care avoids costly dry-clean maintenance.

It’s a practical choice for sleepers seeking extra cushioning for pressure relief, couples wanting improved temperature regulation, renters who need an easy-to-fit cover, and households that prefer machine-washable bedding for straightforward upkeep.
