In our daily lives, when purchasing furniture, we often encounter foam products like sofas and mattresses. At this point, many of us may not know how to discern the quality of the foam, which can be quite troublesome. Worry not, as today's editor introduces how to identify the quality of foam, ensuring a worry-free and hassle-free shopping experience for you.

1. External Identification

Other than the special large and chaotic air holes, the smoother the surface of the sponge and the smaller the air pores, the better.

2. Tensile Strength

Good sponges are not easily torn; anything that can be pierced by a gentle finger tip is definitely shoddy.

3. Feel Identification

The material should be able to quickly bounce back; fluffy foam is preferable, while a stiff and lifeless foam indicates a poor-quality product.

4. Stretch Performance:

High-quality sponges have at least an 80% elongation rate. Those that don't meet this standard are considered low-grade. They look like regular sponges, but the longer they are stretched, the greater the tensile strength.

5. Odor Discrimination

Normal sponges have a slight odor, but an unpleasant smell is usually due to the use of inferior materials.

6. Price Discrimination

Poor quality sponges, which are often mixed with stone powder to significantly reduce costs, are priced lower. High-quality sponges, on the other hand, use polyurethane material and are more expensive.
