Which mattress is right for me?

[Cue]

Hello,

I'm looking for a new mattress like this https://restfaq.com/best-mattress-for-back-sleepers/ . I would appreciate any recommendations as well as what to stay away from. Budget is not an issue. I'm a side sleeper often alternating between sides several times per night. I am not aware of any current mattress induced back pain. However, it's time for a replacement.

Thanks a lot.
