Hi FelixChi,
You’re very welcome!
It’s possible to find something that has a better “deep support” and contributes toward alignment, and still maintain a more plush “upper comfort” that many side sleepers find preferable. There is more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel” that may be useful as well.
There certainly are more offerings out there in the marketplace, and you won’t get any arguments from me that it can be quite confusing for the consumer (purposely so in many instances). That’s part of the reason for this site and an even stronger reason for consumers to become as educated as possible and to learn this information about any mattress they may be considering.
Thank you for the kind words.
Phoenix
