(1) Because the sofa is exposed to more bacteria than the bed, the mite pollution in the sofa cushion is very serious. When people lie down, their mouths and noses are in close contact with bacteria, which is easy to cause allergic diseases or skin diseases.
(2) The sofa is too soft. When people lie on it, their spine will bend and they will feel backache. In the long run, it will cause lumbar musculoskeletal strain and even affect the health of cervical spine.
