Description

Technical Field

[0001] The utility model relates to the technical field of lift chairs, in particular to a multifunctional lift chair. Background Art

[0002] In today's society, seats, especially multifunctional lift chairs, play an important role in people's lives and work. As people's pursuit of work efficiency and quality of life continues to improve, the functionality and comfort requirements of seats are also getting higher and higher. The multifunctional lift chairs currently on the market mainly focus on the adjustment of seat height, backrest angle, etc. to meet the physical needs and work scenarios of different users. Some existing lift chairs may be equipped with simple leg rests, but these leg rests often cannot be adjusted according to the length of the user's legs, and cannot meet the personalized needs of people of different heights, making it inconvenient for users to provide a short and comfortable lunch break. At the same time, the distance between the leg rest and the seat is usually fixed and cannot be adjusted according to the user's actual sitting posture and needs, which limits its flexibility of use. Therefore, we have launched a new multifunctional lift chair. Utility Model Content
