Tempering
The unit is twice tempered. First, each coil is individually
tempered and the entire assembled unit is tempered at 375oC.
This is essential for the shape and longer life of the spring
unit.
The Comfort System
This will consist of 6 overlays:
1. Polypropylene mesh overlay;
2. Needle felt pad;
3. Pre-compressed cotton;
4. Reemay backing;
5. 19mm foam; and
6. Flame retardant cover.
Upholstery Layers
1. A pre-compressed cotton felt upholstery consists of unbroken
laminated garneted cotton made of all new and unused material
regulations, 4.0kg batts per side in 137 x 203 size; 4.6kg
in 153 x 203 size and 5.4kg in 183 x 203 size. The pre-compressed
cotton is placed over the secondary insulator and around
the edge wire.
2. The multi-quilted cover construction is then placed
over the insulator and filling material and fastened by
the flanging process. The multi-quilted process is a sandwich
construction consisting of spun bonded backing, 19mm polyurethane
and the durable flame retardant cover. These elements are
joined together in an attractive multi-needle stitched quilting
design.
Ticking
The ticking is 100% cotton, designed and tested specifically
for hotels. It is flame retardant in accordance with regulations
for the accommodation industry.
Flanging
The flange consists of a strip of high tensile fabric, machine
sewn 15mm inside the outer hem of the top and bottom panels.
The entire insulation and upholstery filling is securely
anchored to the edge of the unit in the form of a snug roll,
by fastening the flanging material to the coils with hog
rings. The flanging process reinforces the edges and keeps
the filling material from shifting.
All Sealy comfort systems are subjected to rigorous accelerated
durability tests conducted at Sealy's International Research
and Development Centre.
Border
Borders are made to the specified 100% cotton ticking and
are in one piece, with the ends securely sewn to each other.
The border is quilted to 6mm polyurethane with spun bonded
polyester backing material.
Identification
Each mattress will have a label attached indicating the
state in which it was manufactured, show the name and address
of the manufacturing location and certify that all materials
are new.
