If you are in market to get yourself a new mattress then this article can be one of your best resources in finding what is best for you.
Most of the mattress brands in Australia use their own trademark names for the basic types of springs they use. So one suppliers “comfocoil” can be exactly same as others “dreamcoil” and in industry term they are bonnell coil. Sound confusing! yes it is but by the time you finish reading this article things will be much clearer for you.
So basically there are two types of coils and for simplification we will call them ordinary coils and pocket coils. The main difference is the interconnectedness of each coil in the mattress.
In ordinary spring system such as bonnell, continuous and offset coil each coil is connected to other by a spring wire. Because there is a connection between these coils when used in a mattress these type of coil moves together when pressure is applied. In simple terms when a person sleeps on this mattress the whole mattress moves with the weight of the person. This restricts the ability of the mattress to adjust to the body. Keep in mind that your back is not flat and if a mattress does not adjust to your back it is going to leave support gaps which in turns can cause back pains and also cause interruption in blood flow by causing pressure points.
Also these coils cannot adjust to different body weights of a couple and heavier person tends to win the mattress, this is also known as roll together. Due to its construction and connectedness the mattress can be very painful for fragile sleeper. In case when one partner moves the other feels tremors too. Please see the picture below to see how these coils are all connected.

Pocket Coils: In pocket coil springs are not connected with each other and thus they behave independently to pressure. Each coil is sewn into fabric pocket and hundreds of them are required to form a queen size mattress. This spring system offers two main benefits.

Because these coils are not attached to wire this allow mattress to offer better support. It allows the heavier parts to sink down while spine stays straight. This gives you healthy blood circulation and improves the quality of sleep.
Second biggest benefit is for couples; while these coils offer a nice bounce for love life they also reduce the motion transfer. So when one partner moves the other gets less affected.
