Zoning

Hi SleepDeprived,

There is more information about zoning and different zoning configurations in post #11 here and the posts it links to.

There are hundreds of different zoned mattresses with a wide range of different firmness levels and zoning configurations so the only way to know whether any specific one would be too firm for you under your hips or would be a good “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) would be based on careful testing (hopefully using the testing guidelines in the tutorial) and/or your actual sleeping experience.
