If you are considering purchasing a new mattress the first thing which you must know is that there is no best kind of mattress for everyone.
Distinct mattresses satisfy different personal preferences, different sleeping positions and different bodies.
Nevertheless there's plenty of information that you can use to get the "best mattress" for you and, if you've got difficulty sleeping, the odds are that you are using a mattress that does not satisfy your body or sleeping habits.
Different types of mattress
The first thing which you have to know about are different kinds of sleep-junkie constructions, i.e. materials. It is because the type of construction will determine that manner the mattress feels in relation to its softness and its ability to shape itself around the body of someone's.
The two chief kinds of mattress building are springs (coils) and foams and you can also get a mixture of both of these substances in one mattress that is certainly typically known as a complex or combination mattress.
Spring or coil mattresses have a "spring count" and this refers to the number of springs in a king size mattress. A high or a low spring count mattress can be soft or firm, but a soft count mattress will always be superior to a low spring count one.
Foam mattresses come in numerous types from standard foam to foam Latex and space age visco elastic memory foam. As with "spring counts" they also have different quality standards and this is generally suggested by the foam's density.
As a general guide the higher the density of the foam the better the quality of the foam (and the firmer and more lasting it'll be). This rule will be somewhat confused by some top end foam mattresses by using two or more different density foams within precisely the same mattress in order to receive the best properties of each foam type within different layers. E.g. the primary body of the mattress may be a high density foam with a top layer of lower density (softer) foam for additional softness.
Which mattress is best for you?
Lots of recent research and orthopedic advice indicates that the best type of mattress is one that shapes and contours around the unique shape of any body.
Envision how a mattress would need to shape and bend in order for that same carriage to be achieved if someone were lying on their side and a good example of how this works is to look at the straight alignment of the back when standing up. I.e. the mattress would have to deflect significantly around the hips and shoulders whilst filling the emptiness area around the waist etc.
A mattress that does this obviously must be pliable and comparatively soft and this has a tendency to suit the contouring foams like Latex and memory foam.
Nonetheless, some folks do sleep better on a more solid and relatively un-giving mattress, despite the fact that this does appear to wriggle the back.
Ultimately, different bodies and different sleeping positions mean that some individuals will like a soft mattress whilst others will prefer a much more solid one. It is very much a matter of personal predilection.
For those who like the feel of foam, but the sleeping characteristics of springs or coils, a composite mattress seeks to join the conventional attributes of springs with a top layer of memory foam or Latex foam for additional body contouring. You can even get gel layers and there's always the alternative of the supreme body contouring mattress - the water bed.
Ultimately, getting a great and restful night's slumber is more about finding out what is the most comfortable subjective mattress option for you rather than going with a tendency or objective advice. Think about your own bed and other beds (e.g. in resorts) that you've slept on. Decide if you prefer a more solid or a softer bed, e.g. if you enjoy a mattress that makes you feel like you're lying on a flat solid foundation, or a mattress that you sink into and that holds you in place.
