I bought the medium firmness back in August and although I have to admit it did take a few weeks to get used to the new foam mattress versus the traditional spring mattress, it was the best purchase I have EVER made. You absolutely can not beat the price, you can't beat the comfort, and you can't beat the quality!! The only reason anyone should hesitate in the slightest is if you are a "hot sleeper" because the foam mattress does cause one to sleep "hotter". I resolved the problem by purchasing a water resistant mattress cover and turning down the air 4 degrees at night. (It really does get that hot) All in all, consider the benefits of comfort, less back pain, and restless nights - I will sleep a little warm :) Absolutely would recommend to anyone interested in making a wise investment. No crush pillowtop, no springs, no turning mattresses anymore. Sweet dreams!
