Technical Field

[0001] This utility model relates to the field of home furnishing technology, and in particular to an adjustable firmness mattress. Background Technology

[0002] As an essential item in daily life, mattresses directly affect people's sleep quality. A mattress mainly consists of three parts: springs, filling, and surface material. The springs determine the mattress's support performance, the filling affects its firmness and comfort, and the surface material determines its feel and appearance.

[0003] In current technology, mattresses are needed to meet daily sleep needs in daily life. However, the firmness of traditional mattresses is fixed and cannot adapt to the sleep needs of different groups of people (such as the elderly, children, and people with lumbar discomfort). Some adjustable firmness mattresses require replacing the filling layer, which is cumbersome and costly. Utility Model Content
