Time to buy ANOTHER mattress. Sigh!!

Just two years later. I THOUGHT I'd get used to the one we have but more n more, I wake up after sleeping 6-7 hours, feeling like I slept on the garage floor. I feel like I have been kidney and rib punched by Mike Tyson. I THOUGHT a firmer mattress would be a good thing but...NOPE! I'm not a big fan of buying Mattresses. Almost like buying a car, these days.
