The Advanced Back Support Plus Topper features LURAcor™ support foam, which offers a more responsive, uplifting feel than traditional memory foam for head-to-toe firm support. It also relieves pressure to help prevent tossing and turning, promoting longer periods of undisturbed sleep. Meanwhile, a cool-to-touch cover feels instantly relaxing, so you can start to unwind from the moment you lie down. Once you’re ready to refresh your sleep space, simply machine wash the cover for years of fresh comfort.
