Do I Need a Box Spring for my Sierra Sleep Mattress?
As a good rule, you should always defer to the manufacturer’s guidelines on what type of foundation or base is recommended for your mattress. Because of constant sleep innovation, today’s mattresses are made to be used on a number of bases such as box springs, box foundations, adjustable foundations, platform beds, slatted bases, and even the floor. Purchasing mattresses and foundations from two different brands may void your mattress warranty. So always check your warranty for details.
