The difference between Pocket Spring and Bonnell Spring

What is a Pocket Spring?

Each spring body operates individually, supports independently, and can be stretched independently. Each spring is packed in fiber bags, non-woven bags or cotton bags, and the spring bags between different rows are bonded to each other with viscose, which is more advanced. The continuous non-contact longitudinal spring technology allows one mattress to achieve the effect of a double mattress

Each spring body operates independently, point-like expansion and contraction, independent support, uniform force between the springs, and individually responds to every movement of the body.

What is a Bonnell Spring?

Bonnell spring 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 higher 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.

Bonnell Spring System-the bonnell spring was Chinese first innerspring unit. Especially developed electronic heat tempering makes the bonnell spring system vitually indestructible, while providing you with the support you need.

All Synwin's Bonnell high tensile steel coil springs pass twice through a constant temperautre, electronically controlled heat temperign process, ensuring there is no break-up under pressure. Not too firm, not too soft--the bonnell unit was developped as a resykt if scuebtufuc research to see that the correct amount of support goes to every party of the body. The steel side supports of the bonnell unit provide added stablility to the very edge of the mattress, increasing the overall sleeping surface.
