There are obvious differences in material, performance and applicable scenarios among sponge, doll cotton and latex in sofa materials. The details are as follows:

Sponge

– Material: It is a synthetic material made of polyurethane foam.
– Characteristics:
– It has good elasticity and resilience, strong support, and can adjust its shape according to pressure.
– There is a large difference in density. High-density sponge is durable and not easy to collapse, while low-density sponge is soft but easy to deform.
– The air permeability is average, it may be stuffy, and the price is relatively moderate.
– Applicable scenarios: It is often used for the main filling of sofa cushions and backrests to provide basic support.

Doll cotton (also called polyester fiber cotton)

– Material: It is artificial cotton made of polyester fiber through processing.
– Characteristics:
– It is light and soft in texture, fluffy in hand feel, similar to cotton but more elastic.
– It has good air permeability, is not easy to harden, but has weak resilience and poor support.
– It is cheap and easy to clean, but may collapse slightly after long-term use.
– Applicable scenarios: It is mostly used as filling for sofa throw pillows and cushions, or used at the edges and folds of sofas to increase softness.

Latex

– Material: Natural latex is made from the sap of rubber trees, and there is also artificial synthetic latex.
– Characteristics:
– It has excellent elasticity and strong resilience, can fit the body curve, and has a good balance between support and comfort.
– Natural latex has good air permeability, certain bacteriostatic and anti-mite effects, and a delicate touch.
– The price is relatively high. Natural latex is durable, but it is afraid of direct sunlight and high temperature.
– Applicable scenarios: It is often used for filling cushions and backrests of high-end sofas, which is a choice for pursuing comfort and health.
