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 bonnel spring mattressKnitted Fabric:Knitted fabrics are the 3rd major class of fabric, after woven and nonwoven fabrics. The elasticity of knitted fabrics gives them an excellent drape, but this is opposed somewhat by their generally greater thickness compared to wovens. For this reason, knitted fabrics resist wrinkles better than wovens, but do not generally take a crease.Knitted fabrics are generally warmer and more comfortable than woven fabrics, which is why they are worn closer to the body.Features 1Bonnel spring, which has undergone 250 degrees high temperature treatment.
