The Tempur-Pedic TEMPUR-Serenity Mattress Topper transforms the feel of any existing mattress with 3 inches of Tempur-Pedic's proprietary TEMPUR-Material® memory foam. Designed for the California King size (71" x 83"), it instantly adapts to your weight, shape, and temperature, providing deeply personalized support and pressure relief throughout the night.

The topper features a high-stretch knit performance cover with moisture-wicking properties that is removable and machine washable, making it easy to keep fresh and clean. Corner straps secure the topper to your mattress and prevent shifting during sleep. The TEMPUR-Material® foam is engineered to be more breathable and more durable than conventional memory foam, resisting sagging and returning to its original shape over time. The cover is resistant to dust mites and allergens, making it a thoughtful option for allergy-sensitive sleepers. The topper is designed and assembled in the USA and is compatible with mattresses up to 13 inches tall.

The slow-response, body-contouring feel makes this topper especially well-suited for side and back sleepers who want to soften a firmer mattress or add a plush, cushioning layer to their sleep surface. A 10-year limited warranty is included.
