Mattress Forum

I'm currently sleeping on an old standard queen mattress with a thin cheapo sponge/foam topper.  It doesnt have near enough give and is simply too hard for sleeping on my side.   My plans are to replace my mattress and topper for some newer, better quality components.  

My new mattress would be a standard firm queen.  I want to use a 3inch thick, 5lb memory foam topper and then above that a fitted plush pillow topper.   Would that be a good solution to my side sleeping pains?

The expensive mattress route for me doesnt sound good.  I've seen all types of mattresses go flat with time requireing the whole thing be replaced.  Worn toppers are cheaper and easier to replace.

Other suggestions welcomed.

Thanks
