Multi -function sofa was first popular in Europe and the United States, also known as the first -class cockpit sofa. Boeing and Airbus's VIP seats are the earliest sofa versions.

Multifunctional sofas have been popular in China! After more than 20 years of development, it has continued to the third -generation standard. Here we will focus on the generation of generations of the sofa.

The first-generation electric sofa needs to keep a distance of 15-25 cm. When lying down, the back is leaning backwards. The appearance is more inclined to bread style, which is bulky. Most of the doll cotton pillow armrests are filled with the head. The style tends to be soft and the package is strong. The disadvantage is that the deformation is fast and the occupation area is large.

The second -generation electric sofa must first meet a hard indicator, with zero wall design. The back is close to the wall, which can also be lying down. The overall lying down and stretching forward. The second -generation design is more user -friendly, and the use of sponge filling area is getting larger and larger. Design more considering ergonomics, the seats become soft and hard. No longer biased towards extreme softness.

The third -generation electric sofa must be integrated into the minimalist style, and at the same time, it needs to meet the design of high -lifting. This design is more ventilated and avoids moisture. It's easier to clean and clean. The style is more simplified and the appearance is more grade. This type of design basically uses sponge filling. Activity headrest was used back. The iron frame is suspended. Of course, there are also disadvantages. The mechanical performance of the sofa must not have the first generation. There is no first -generation cost -effective. But it is in line with the mainstream style of the current designer. After all, the trend determines the purchase of consumers.

Maybe the fourth -generation electric sofa is more inclined to intelligent and more anthropomorphic. More integrated into smart home life. Directly access the Internet of Things system. It is no longer as simple as a sofa, it may play a member of the members of the home. Accompany the old and small time.
