Lazy sofa is an adjustable and comfortable furniture, usually made of filling materials and cloth. It aims to provide comfortable support and relaxed feeling, so that people can sit or lie down comfortably.

Sitting on the sofa for a long time may have negative effects on the body, such as increasing the risk of obesity, causing muscle fatigue and discomfort, and increasing the risk of neck and back pain. Therefore, it is suggested that lazy people should pay attention to maintaining the correct posture when using lounge chairs, avoid sitting still for a long time, and carry out appropriate stretching and exercise.
