Niagara Sleep Solution Ultra Soft Cooling Mattress Topper — King Size, Bamboo-Derived, Deep Pocket Fit

Niagara Sleep Solution Ultra Soft & Cooling Mattress Topper (King) is a bamboo-derived, ultra-soft 78"×80" cooling topper that adds cloud-like cushioning and sweat-wicking comfort to mattresses 8–20" deep.

This king-size topper blends rayon from bamboo fiber with a plush fill to create a breathable, gentle sleeping surface that helps regulate temperature and reduce pressure points. It ships compressed for easy handling, expands to full loft after airing or a short low-heat tumble dry, and is machine-washable without latex or harsh chemicals.

How does this topper keep nights cooler?

The bamboo-derived rayon cover is naturally breathable and helps move moisture away from skin, while the airy fill increases airflow across the sleep surface. Together they reduce trapped heat and create a fresher feel through the night.

• Rayon from bamboo fiber cover for moisture-wicking
• Plush, lofty fill that improves ventilation
• Designed to fit mattresses 8–20" deep to avoid bunching

Will it fit my thick king mattress and stay in place?

The topper is sized 78×80 inches for standard king beds and features extra-length stretchy sides and a deep pocket to accommodate thicknesses from 8 to 20 inches. The snug skirt helps keep the topper securely positioned without frequent readjusting.

• Deep pocket construction for thick mattresses
• Extra-stretch sides for a tight fit

How do I care for and set up the topper after unboxing?
