You did a lot of research and paid a lot of money to get the mattress of your dreams. The materials inside your mattress and how its constructed will determine how your mattress holds up. Innerspring mattresses with tempered steel coils will give you better, longer lasting support than layers of all foam. Materials like latex on top of individually pocketed innersprings, will retain better loft and show less body impressions than memory or polyurethane foams. So, try this simple program to avoid those dips and valleys.
Research shows it takes 30-60 days for you to get use to your new mattress and for it to get use to you. The chore of flipping your mattress is no longer necessary. You can improve long range performance by rotating your new mattress every quarter for the first year, then once every six months. A rotation is 1 turn of the mattress, putting the head at the foot and the foot at the head of the bed. The reason is physics; most couples are different weight, height and shapes, yet we tend to sleep in the same spot, in the same position(s) night after night. By rotating your mattress you sleep on different sides without actually having to change sides. Once a year its advised to also rotate your foundation or boxspring head to foot. A King or Cal King Set comes with 1 mattress and 2 foundations, you should switch the foundations from one side to the other and rotate each head to foot. Same goes for Split Queen foundations.
A simple rotation schedule will even out wear & tear and help you get use to your new mattress more quickly. While all mattresses naturally soften over time and with use, by rotating your mattress and foundations you will get many more years of sleeping well.
