It's been far too long since I've bought a mattress (9 years?). Mine is dying. DH bought a mattress right before we met and it was awful- to the point that we are now sleeping on my old mattress. We're waking up achy so we know that it's time to buy a new one.
What can you tell me about buying a mattress? I know someone here used to sell them (chibiyui?) and I'm sure many of you have bought them before.
Also, do I need to replace the box spring? It looks ok but don't know how to tell if it's worn out.
