The Simmons ComforPedic memory foam mattress collection is going head-to-head with Tempur-Pedic. Simmons is running commercials that prompt customers to try Tempur-Pedic and ComforPedic mattresses side-by-side. ComforPedic are available in a wide range of styles each with different layers and features. Owner reviews are quite good and praise ComforPedic mattresses for their ability to alleviate joint pain and limit motion transfer. They are also reportedly very comfortable and don’t sleep hot. On the downside, they tend to be a bit expensive and are also heavy.
