A high quality mattress isn't cheap, with prices ranging from a few hundred all the way to a few thousand dollars. How do you get the most bang for your buck? In most cases the answer is to choose an online mattress retailer. Physical retail locations have huge overhead, and the online sellers don't play on the same field. Since they all have great return policies, you should definitely try one out.
A good quality mattress will last many years, but unlike a diamond - they aren't forever. A general rule of thumb is that you should consider replacing your mattress after 8 years or so. If you find yourself waking up with joint pain, have trouble sleeping through the night, or just aren't feeling rested after a night's sleep, you should definitely think about a replacement.
The firmness of a mattress refers to how soft it feels, and is a somewhat subjective measurement. Don't confuse this with the support it provides, as that's more a measure of how well it holds your back in position. Firm mattresses may provide great or horrible support, and the same is true for softer options. Find a blend that works for you!
