The Niagara Sleep Solution Ultra Soft California King Mattress Topper is designed with comfort and cooling in mind. Its top layer combines polyester and bamboo-derived rayon, making it gentle on sensitive skin and naturally breathable.

The topper is plush and adds a soft, cloud-like feel to your mattress, providing extra cushioning and some back support.

It fits mattresses from 8 to 20 inches deep thanks to its deep pockets and stretchy sides, which helps it stay in place without sliding off. You can easily machine wash it, and it's free from latex and formaldehyde, which may appeal to allergy sufferers. It’s not water-resistant, so spills might soak through if you’re not careful.
