The sofa stuff There are three main parts

A. Soft polyurethane foam (commonly known as a sponge)

for the three major sub-categories

Conventional sponge is a conventional TDI and polyether as the main formation of sponge. Characterized by a good back flexibility, softness and breathability.

High Rebound is a sponge activity and phosphorus-generation TDI as the main body of the sponge, characterized by excellent mechanical properties, better flexibility. Compression load, fire, good air permeability.

Chaos is a cavernous hole by hole size of the algae similar to that of a natural sponge, which is characterized by flexibility, compression, rebound with an excellent time of the buffer.

B. Stuffing down:

So down-filled sofa, sitting comfort and long-term use of small deformation, the disadvantage is the slow rebound, the high cost. In general with high-level sofa with a sponge, or the use of

to do.

C. Man-made cotton stuffing:

Man-made cotton sofa stuff, an

, ride comfort, but the mechanical properties of the poor, small compression load, only to do a cushion.

The sofa stuff of choice: According to the different types of stuff, use very different. Under normal circumstances, the cloth sofa cushion stuff should be 30 kg / m rebound high above the sponge is more appropriate, in the form of block foam used to fill most of the way, the best form of a 30 kg / cubic meter over

and sponge combination of down-hole arbitrary or superimposed Rayon combined increase comfort and service life. To choose when to ask the type of stuff, stuff sponge is used to understand the density of the sponge, with feelings of gravity cushion the effect of the rebound, got to sit feeling a sense of comfort and so on. General use of the sponge cushion, the National Institute of Standards 25KG/M3, international standards 35KG/M3. Bottom structure, high-elastic bandage is superior to the structure of the snake spring structure, better than the poor quality bandage bandage structure in the two above-mentioned principle, the European high-level sofa commonly used sandwich structure design.
