Do I really need a new mattress?

Maybe and maybe not. Your mattress doesn't necessarily have to be falling apart for it to need replacing. If you're tossing and turning at night and not getting the rest you need, there is the definite possibility that it may be due to a worn out mattress. Most experts suggest evaluating your mattress twice a year for comfort and support, although, in reality, you are more likely to just head to a store once you start to feel uncomfortable. If the cover on your mattress is threadbare or if your mattress is excessively sagging, you might want to start thinking about replacing your sleep set. After 10 years, you will probably find your current mattress considerably less comfortable than a new one. If you have recently moved and have more space in your bedroom, you may also want to consider moving up to a larger size for more room.
