For all our premium products, we’ve applied scientific knowledge and expertise. Our engineers understand that replacing an uncomfortable mattress can lead to improved sleep quality and decreased back pain. Therefore, all our premium mattresses are made with the most advanced materials and technology available: temperature-stable Clini-Foam™. Layers of Clini-Foam™ with airflow technology help to cushion and support our customers. In that way, we provide a less sweaty, more comfortable night’s sleep. What’s more, our antimicrobial mattress covers may reduce odors and dust mites. We’re so confident that you’ll prefer our high-quality mattresses that we offer a 120-day trial period on our best mattresses.
