The reason why upholstery fabric A is identified as unsuitable for use in a hospital due to ease of cleaning is likely related to its composition and finish. In healthcare environments, it is critical to maintain high standards of hygiene. Fabrics that can be easily cleaned and sanitized are necessary to prevent the spread of infections and maintain a safe environment for patients.

Hospitals require fabrics that are resistant to stains, have antimicrobial properties, and can withstand frequent cleaning with strong disinfectants. If upholstery fabric A lacks these qualities—perhaps it is textured, porous, or made from a material that traps dirt and moisture—it would not meet the rigorous standards necessary in a hospital setting.

In contrast, the other fabrics (B, C, and D) probably have features that make them more suitable for commercial cleaning processes, such as being made from synthetic fibers that resist staining and can be easily wiped down or washed. They may also have finishes that enhance their cleanability while still providing comfort and durability. Understanding these aspects of fabric choice is essential for ensuring health and safety in interior design, especially in sensitive environments like hospitals.
