Open-coil Mattresses

The open coil mattresses offer basic support using a tier of hourglass-shaped springs held together in rows by helical wires. This type of springing is also used in sprung divan. The term 'gauge' refers to the diameter of the spring and how tightly it is coiled. The tighter the coil, the firmer the feel of the mattress,15 gauge is quite soft with 12.5 gauge being fairly firm in feel. This frame is then placed within the base of the mattress frame and secured with stitching. The frame is filled with a variety of fillings which will differ according to the quality of the mattress. The mattress is finally overlaid with more layers of fillings placed on top of the spring unit to create a comfortable sleeping surface. These fillings are secured using either a stitching method called 'micro-quilting' or 'panel quilting' which holds the fillings in place running a stitch across the surface of the mattress in a pattern creating a flat surface, or by 'hand tufting', which involves pinning the fillings at specific points on the surface of the mattress with a long stitch that runs from the surface down through the inside of the mattress to the core of the spring unit, they look like buttons pressed onto the mattress and create a wavy surface.
