The comfort of the sofa is related to the seat structure, padding and fabric of the sofa.
Below we explain their differences from these three different aspects.
The seat structure is the main part of the sofa that is stressed, and it is also the key part of the sofa's comfort and service life.
Seat structure
It is good elasticity but short service life, easy to collapse.
It is inelastic, poor sitting feeling but long service life.
It is good elasticity, good sitting feeling, use long life.
Sofa padding
There are three main types of padding for sofas.
High resilience foam is a kind of sponge produced by active poly phosphorus and TDI as the main body. It has excellent mechanical properties, good elasticity, large compressive load, flame resistance and good air permeability.
Feather is used as sofa filling, it is comfortable to sit, and has little deformation after long-term use. The disadvantage is slow rebound and high cost. It is generally used in conjunction with sponge in high-end sofas, or suitable for use as cushions.
Artificial cotton is used as a sofa padding, which has excellent softness and comfortable sitting feeling, but it has poor mechanical properties and small compression load, so it is only suitable for cushions.
