The main differences between Class A and Class B bedding are reflected in safety standards, applicable populations, material selection, and usage scenarios, as follows:

1、 Differences in safety standards

Class A: Suitable for infants, young children, or sensitive populations, it must meet the highest national safety standards, with formaldehyde content ≤ 10mg/kg, and strict restrictions on color fastness, pH value, and degradable carcinogenic aromatic amine dyes.

Class B: Suitable for adults, with moderate safety standards, formaldehyde content usually ranging from 10-75mg/kg, and color fastness, pH value, and other requirements lower than Class A.

2、 Applicable population

Class A: Designed specifically for infants and young children (0-24 months), or for people with sensitive skin.

Class B: Suitable for adults and children (not infants and young children), covering the needs of teenagers, renters, and others.

3、 Material and Craftsmanship

Class A: It mostly uses skin friendly materials such as pure cotton, natural latex, and seasonal cotton, with fine manufacturing processes (such as high-density weaving and antibacterial treatment) to ensure softness and breathability.

Class B: Common synthetic materials such as polyester and polyester fibers, with relatively simple processes and more affordable prices.

4、 Usage scenarios

Class A: Direct contact with infant skin, such as bed sheets, duvet covers, pillowcases, etc.

Class B: It also comes into direct contact with the skin, but has a wider range of applications, such as adult bedding, children's bedding, etc.

5、 Other differences

Formaldehyde content: Class A ≤ 10mg/kg, Class B 10-75mg/kg.

Color fastness: Class A is more resistant to fading, while Class B is prone to fading.

PH value: Class A is close to the skin pH value, while Class B may have slight deviations.

Summary: Class A focuses on high safety and is suitable for infants, young children, and sensitive populations; B-class combines cost-effectiveness and is suitable for daily use by adults. When making a purchase, it is necessary to choose the corresponding category based on actual needs and the target audience.
