Spring Core - Heart of the mattress.

The core of the mattress is the most important part ( Heart of a spring Mattress )in the support of the body.It is made up of steel coils springs, also known simply as coils. The spring mattress core is also called innerspring.Proper support is where the wire coils push back in response to weight deflection to hold the body in alignment.

Number of coils
Basically, the more coils a mattress has, the more support it will give the user. As a general rule, very firm mattresses have a high coil count. Generally, but depending on the mattress size, they come with 300 to 800 coils. Depending on the size, 500 to 800 coils is considered firm. However, some expensive and comfortable mattress only have around 400 coils. and it takes as few as 312 coils in a full mattress to provide decent support. This where cost varies from brand to brand and model to model.

Gauge of the coils
Obviously, heavy gauge (thick) coils will offer a great deal of support while light gauge coils will give less support. A low coil count and heavy gauge wire can pass as a firm mattress in the store, but it is likely that this mattress will become lumpy quickly because it does not have enough coils.

Apart from coils the thickness of border wire also has to be seen. Border wire gives edge support for the mattress as any person sits on the borders while getting into or out of the mattress.

Types of coils
There are two types of coils - Bonnell & Pocketed.



Bonnell - These are the oldest ones and most commonly used. They have an hour-glass shape, and the ends of the wire are knotted. Then each spring is connected in the spring unit through a helical wire.

Pocketed - They are individually pocketed in fabric pockets so that the coils respond individually. when one person tosses and turns, the other doesn't feel it because of this.

You might think that all Spring mattress brands are the same , still they vary in prices. These are very important factors which you have to look into while comparing prices of differet brands.you should always choose the one which would give you value for money.
