Spring Mattresses - Bonnell Spring & Pocket Spring

Bonnell Spring Mattress

The Bonnell spring is the classic Spring Unit, and has, through the years, proven its worth. It is made from around hourglass shaped springs which are tied together to form a mat. A round helical crosswise connects each single spring to a spring unit.

Different thickness (gauge) of wire in the springs makes a harder or softer mattress. The lower the gauge, the firmer the mattress. The number of springs per mattress type is one of the key quality characteristics of a bonnell spring mattress.
 

Pocket Spring Mattresses

 
  Pocket spring mattresses contain pre-stressed springs inserted into individual fleece or cotton pockets and then clipped among one another or glued on top, middle or bottom. It is the point-by-point elasticity that distinguishes itself from others. The greater number of springs allows more flexibility so that the mattress can better mould to the body shape.
This type of mattress is generally considered as the best that spring units can offer and is normally the most expensive type of product. It is higher priced because manufacturing is more complex.
