Simmons Beautyrest mattresses have been around for a very long time. This has given Simmons a chance to perfect their mattresses so that you can get to sleep easier. Developing the pocket coil system was the perfect base for their mattresses. Over the years they have been at the center of mattress innovations. In more recent years they have developed hybrid technology that has been infused with their proven pocket coil system. The foams that Simmons uses for their hybrid mattresses encourage airflow. This helps alleviate the ‘hot’ feeling that some users complain about when using a foam mattress. The Simmons hybrid mattresses are packed with cooling technology. This is a prime example of Simmons seeing that the customers are not happy with something and changing it to suit the needs of the people. Simmons is a company that has been around since the early 1900s and is a company that you can trust is going to give you a quality product.
