Rotate your mattress on a regular basis. Monthly is the recommended frequency per my Bedding & Mattresses FAQ.
• Don't forget about that foundation! This will need to be rotated as well.
• Avoid using the mattress handles to support the full weight of the mattress. Handles are for positioning the mattress over the foundation.
• Foundations are made to work with your mattress to provide a comfortable sleep environment. When you need a new mattress (at least every 10 years), you also need a new foundation. Bob’s recommends replacing the set to keep warranties intact.
• Vacuum your mattress and foundation for general maintenance.
•Many manufacturers will void a mattress warranty due to staining. That's why I highly recommend my Goof Proof Mattress Protectors to protect your mattress from soils and stains!
