Is a Tempur-Pedic mattress worth the extra cost overall? Simmons Beautyrest mattress or other brands? It depends on your sleep preference. Tempur-Pedic tends to suit people who want close body contouring, comfort, and motion isolation, while Beautyrest is cold-based, hybrid design, suit people who prefer more traditional bounces, edge support, and airflow. Neither is objectively better.

It comes down to preference. All I can tell you is gallery sold. Thousands and thousands of Tempur-Pedic mattresses over the last 20 years.
People rave about how great they sleep every night.
