Back Sensor is a 3 zoned Bonnell Spring extra firm mattress. Bonnell springs are a firmer spring system hence it is designed to provide a firm support for the body. The Centre third of the mattress has extra firm springs to provide extra support for the back. These springs have special edge wire along the perimeter of the mattress with butterfly spring edge support giving extra support along the edges so that when you sit on the mattress, it does not collapse under your weight. If the sides collapse, it can cause a person to slide down whilst sitting on the side to get in and out of the bed. The side supports allow a person to sleep right to the edge of the mattress enabling you to utilise the full sleeping area. Generally, imported mattresses or mattresses delivered in a box do not come with any of these supports hence they are cheaper. The side supports also provide the stability in the mattress.
The 3 zoned Bonnell Spring System is a proven technology spring system which has been used in mattresses in Australia for over 100 years. It is reknowned for its firm support structure in mattresses. It is the best spring system to keep the body straight with extra padding used to contour around the body.
Back Sensor comes with a very high density firm padding on both sides of the mattress. The thickness and depth of the padding not only gives a firm feel to the mattress but it provides superior support. It is a double sided mattress, which means it can be flipped and rotated.

A high quality knitted fabric and a firm quilting on top gives an overall medium firm feel to the mattress. Back Sensor is a very good mattress without a pillow top for people looking for firmness with a good side support. It’s an excellent mattress for adults looking for firmness. It provides superior comfort and support while providing good value for money. This mattress is made in Australia and comes with a ten year warranty.
