Hi calderon,
[quote]After sleeping on the mattress for a few weeks, I noticed my hips and legs going numb after sleeping on my side. The mattress feels great when lying on my back but I prefer sleeping on my side.

While I can’t feel what you feel on the mattress and there are too many unknowns, variables, and personal preferences involved to make any specific suggestions based on specs (either yours or a mattress) or “theory” in terms of PPP (see mattress firmness/comfort levels in post #2 here) … there are some suggestions in post #2 here that may be helpful while you are still going through the initial adjustment and break in period for your mattress.
There is also 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” that may help you identify the types of changes that might help you sleep better.
It would certainly be worthwhile to talk with Dormio about the options you have to make changes to the mattress but if you still notice the same “symptoms” after a little longer period of time (or after trying some of the other suggestions in the post I linked) then it would likely mean that the upper layers are a little to firm for you and it may be worth considering changing the firmness of the upper layers if that’s an option that you have available. Changing the firmness of the support core from firm to medium would also have “some effect” on the firmness of the sleeping surface (every layer affects the feel and performance of all the other layers and the mattress as a whole) and would likely still provide you with good primary support at your body weight but it may not be as effective as softening up the upper layers of your sleeping system if the “symptoms” you are experiencing are more related to pressure relief and “comfort” than with support/alignment.
