I've had my new Equalizer mattress from Jamison for three nights (which I know is a short time). It is composed of a 3" Talalay Latex (24 ILD) top over a 7" foam core. I bought the box that came with the mattress. I previously had a 10-year old Sealy Posturpedic innerspring mattress that was too hard for me as a side-sleeper.

My new mattress seems comfortable at first but I seem to sink too much, and I am waking up with lower back pain which I did not have before. I sleep on my side with a pillow between my legs. I am 5'6" and about 195 lbs.

I am not sure if the Talalay Latex is too soft, or if the problem is that I am sinking through to the foam core which is too hard.

At this point, I want to know what my options might be. Would some kind of mattress topper make it better, or worse? Or, should I just give it some time? Anyone have any suggestions?
