What it is

The Niagara Sleep Solution mattress topper is a California King size layer measuring 72 by 84 inches and 15 inches thick. It is made from rayon derived from bamboo fiber and has a plush, pull-on design with deep pockets that fit mattresses 8 to 20 inches deep. The topper is machine washable and ships compressed for easy handling.

Cooling limits

The topper uses bamboo-derived rayon for a cool, sweat-absorbent surface but has no active temperature control system. It is not water resistant, so spills will soak through unless a protector is added. Cooling performance depends on room airflow and the sleeper's body heat, not on a powered mechanism.

Capacity and headroom

The 15-inch profile adds substantial cushioning for full-body support on a California King bed. Deep-pocket sides with extra-length stretch accommodate thick mattresses up to 20 inches without sliding off. After unpacking, the topper requires 48 hours to fully expand or 20 minutes of low-heat tumble drying before use.
