Hi KayJazz,
There isn’t really any way for me to know for certain outside of generic suggestions because I can’t feel what you feel or see you on the mattress. In general your best course of action would be a more detailed conversation with a manufacturer that can cover much more ground than the more limited depth of information that is possible on a forum.
Having said that … there are some general suggestions in post #2 here that talk about some of the more common “symptoms” on a mattress and some potential solutions.
The first step would be to decide whether your mattress is too soft or too firm in either the comfort or support layers and whether your hip pain is from pressure points or because your hips are sinking into the mattress too far and flexing the hip joint out of its neutral alignment.
If your comfort layers are too firm and causing pressure points then a topper or a thicker or softer comfort layer can be helpful.
If you are sinking down too far into the mattress and are having alignment issues but the pressure relief is good … then a firmer support layer may be helpful.
