What is the difference between Class A and Class B bedding?

The core distinction between Class A and Class B bedding lies in safety standards, target users, and material requirements. Simply put, Class A is safer and more stringent, suitable for infants, young children, and those with sensitive skin; Class B prioritizes cost-effectiveness and is ideal for daily adult use.

I. Safety Standards: Class A Imposes Stricter Requirements
Class A: Formaldehyde content ≤10mg/kg, pH value must be skin-friendly (4.0-7.5), high colorfastness, and prohibits the use of azo dyes that can release carcinogenic aromatic amines. Infant products must meet Class A standards.
Class B: Formaldehyde content ≤75mg/kg, pH value range 4.0-8.5, and relatively relaxed colorfastness requirements. Applicable to textiles in direct skin contact with adults.
II. Target Audience: Choose Appropriately
Class A: Designed specifically for infants aged 0-24 months, such as sheets, duvet covers, and diapers. Also suitable for individuals with allergies.
Class B: Suitable for adults and children's bedding like sheets, duvet covers, and pillowcases. Class B is not recommended for infants.
III. Materials and Uses: Natural vs. Synthetic Fibers
Class A: Primarily uses natural materials like pure cotton, linen, and bamboo fiber, offering breathability, moisture absorption, and skin-friendly properties.
Class B: Often contains synthetic fibers such as polyester and acrylic, which are lower in cost but less breathable and prone to static electricity.
IV. Price and Selection
Category A: Higher prices due to stricter safety standards and increased production costs.
Category B: Offers better value for money, suitable for general consumer use.

Summary: Choose Category A for babies and Category B for adult daily use. Safety comes first, comfort second.
