Cotton Topper for King Beds

The Niagara Sleep Solution Cotton Mattress Topper fits king-size mattresses measuring 78 by 80 inches and adds a 15-inch plush layer. It is designed for sleepers who want a softer, cooler surface without replacing their existing mattress. The deep elasticated pockets stretch to accommodate mattress depths from 8 to 20 inches.

Machine-Washable Cotton Cover

The 100 per cent cotton top is breathable and wicks moisture, helping to reduce heat build-up during the night. Because the topper is fully machine washable, it stays fresh with regular laundering and regains its loft after drying. No water-resistant coating is applied, so liquids will soak through to the mattress beneath.

Plush Comfort Within Depth Limits

The 15-inch thickness provides cloud-like cushioning and full back support for side and back sleepers on mattresses up to 20 inches deep. It will not fit securely on mattresses deeper than 20 inches, and buyers who need a waterproof barrier or a firmer feel should consider other options.

Questions about this item

Will the 15 inch cotton topper need any special care to keep its plush feel over time?

Machine wash the 100 % cotton cover on a gentle cycle and tumble dry low; the fabric stays fluffy after drying without extra treatments.

What is the deepest mattress the 78x80 king topper can fit before the stretchy sides lose grip?

The deep-pocket design stretches to accommodate mattresses up to 20 inches thick while keeping the topper secure.

Does the cotton topper sleep hot when used every night through summer?

The breathable cotton surface wicks sweat and promotes airflow, so the topper stays cool during continuous all-night use.
