Niagara Sleep Solution King Ultra-Soft Mattress Topper — 78 x 80 in King, Bamboo-rayon Cooling & Pressure Relief

Niagara Sleep Solution King Ultra Soft Mattress Topper is an ultra-soft bamboo-rayon topper (78 x 80 in) that adds cloud-like cushioning, cooling performance, and improved pressure relief for heavier sleepers and those with sensitive skin.

Upgrade a firm or worn mattress with this king-size topper made from rayon derived from bamboo fiber. Designed to fit mattresses 8–20 inches deep, the 78 x 80 inch topper provides a plush surface that helps dissipate heat and wick moisture. It ships compressed for easy handling; shake and allow 48 hours to loft or tumble dry 20 minutes on low to restore full thickness.

How does this topper help make a firm mattress feel softer?

The Ultra Soft topper adds a generous layer of cushioning that redistributes surface pressure so hips and shoulders sink slightly instead of pressing on a hard mattress. That immediate softness can reduce tossing and create a more comfortable sleep surface without replacing the whole bed.

• 78 x 80 inch king size covers the entire mattress surface
• Bamboo-rayon fabric provides a silky, gentle feel against skin
• Plush fill creates a cloud-like layer for pressure redistribution

Will this mattress topper help if I sleep hot or sweat at night?

The topper uses bamboo-derived rayon, a breathable textile that moves moisture away from the body and helps regulate temperature. While not an active cooling technology, its sweat-absorbent fabric and airy fill improve airflow compared with many dense toppers.

• Breathable bamboo-rayon surface wicks moisture
• Lofty fill promotes better air circulation than flat pads
• Works well with breathable sheets and cooling pillow options

How easy is it to put on, care for, and keep in place?

The deep-pocket design and extra-length stretchy sides make the topper simple to install on mattresses from 8 to 20 inches deep. It's machine-washable and free from latex and formaldehyde, so routine cleaning is straightforward; follow the care suggestions to preserve loft and shape.

• Deep pockets and stretch sides fit thick mattresses securely
• Machine-washable for easy maintenance
• Compressed packaging requires 48 hours to fully expand or 20-minute low tumble dry
