Hi SleepNYC,
Thanks for the feedback … I appreciate it 
I would make sure you sleep on the mattress for a few weeks before doing anything so it has a chance to break in and you have a chance to adjust to a new sleeping surface but if you do decide that you need a topper then post #2 here and the topper guidelines it links to will help you use your sleeping experience as a reference point in choosing a topper that will have the best chance of working well for you.
