The Novaform Serafina TriComfort 3-Inch Gel Memory Foam Mattress Topper transforms your existing mattress with a premium layer of cooling comfort designed for Queen-size beds. The topper features Novaform's proprietary TriComfort technology, which delivers a balanced feel — neither too firm nor too soft — by combining three distinct foam formulations in a single 3-inch layer.

Gel-infused memory foam helps dissipate heat away from your body throughout the night, making this topper well-suited for hot sleepers. The foam conforms to your body's natural contours to relieve pressure points, reduce tossing and turning, and promote deeper, more restorative sleep. The topper is CertiPUR-US certified, meaning the foam has been tested and verified to be free of harmful chemicals and meets rigorous standards for content, emissions, and durability.

A soft, machine-washable cotton cover is included and fits mattresses up to 18 inches deep, keeping the topper securely in place. The topper is proudly made in the USA by Novaform, a brand known for delivering high-quality sleep products exclusively through Costco.
