The spring unit is a five-turn Bonnell spring system, made from premium heat tempered steel providing the correct support required.
Side Edge Support
This support system helps protect and prolong the edge of the mattress from collapsing. By strengthening the border wires, optimum edge firmness is achieved as well as increasing the total sleeping surface.
To prevent the upper foam and materials against coil damage, heavy duty polyester blanketing is placed onto spring system. This also helps distribute the weight of the body over the entire spring unit, not just in the lying position area. The shield guard is located in between the blanket, providing body support and anti-sagging protection.
Each side has a double comfort layer of 18mm 19-130 grade foams, treated with Ultra-Fresh TM to inhibit the growth of bacteria, mould and mildew and provide effective control of dust mites. Treated foams tend to have a longer life than untreated foams.
High quality, knitted fabric puff quilted with a 300-gram layer of Poly and 15mm Health-Guard TM treated quilt foam.
