When your mattress is worn out, you might decide to buy a new one as soon as possible. But if you think it will be as easy as running down to the store and getting a new one, then you will be mistaken. A lot of thought and careful research is required to do it right. There are hundreds of different companies selling that many models, and what kind of mattress is good for you will depend on a lot of things including your body type.
Consult your doctor
This might seem a little weird in the context of buying a new mattress, but if you have any health condition especially persistent or chronic pain then you ought to consult a doctor and take a few pointers before embarking on your journey to get best mattress.
Comfortable but firm:
Too soft mattresses are often the cause for back pains. So, some people tend to go for extra firm mattresses. This might not be as good an idea as you think, too firm a mattress might feel like a stone slab and would probably be a hindrance to your sleep. A medium firm mattress is a better option as your body will be well supported and you would still feel comfortable.
Size and weight matters
As mentioned earlier, your body type will play a role in mattress selection. If you are a of a large and heavy build then you will probably need a thick mattress so that when you sleep there will be some extra padding between you and the coils or support system underlying the mattress. A person who is slight and weighs less can easily find the same level of comfort with a thinner blanket. So in order to get best mattress you will have to take your body type into account.
