Simmons recommends that you test the beds on the retail show floor to determine your personal comfort preference. Lie down on each mattress to help you decide which model is best suited to your needs. Many components make up the feel of a mattress – such as coil unit construction, foam and upholstery layers, and cover fabric. Ultimately, the exact Simmons mattress you choose will depend on your personal preferences and the sleep benefits the model delivers. As a comparison guide you may take note of brand class (i.e., Beautyrest®, Connoisseur™, World Class®, BackCare®, BackCare® Ultimate™ Series and BackCare® Advanced™, etc), coil unit construction and comfort level to help you select the appropriate Simmons bed. As a rule of thumb, we recommend you to try a maximum of three mattresses at any one time. Anything more would simply confuse you.
