Description
Technical Field
[0001] The utility model relates to the technical field of furniture, in particular to a sofa. Background Art
[0002] Sofas are popular among consumers for their good elasticity and sitting feel. The good sitting feel of sofas is mainly provided by multiple snake springs and sponge layers at the base. Among them, the snake springs can provide a relatively hard sitting feel to prevent users from feeling a lack of "support" when sitting down, while the sponge layer can make users feel soft and comfortable.
[0003] In the prior art, both ends of the snake spring are fixedly connected to the base. When a user sits in the middle of the sofa, the weight of the person is mainly concentrated on the middle of 1-2 snake springs in the middle of the sofa. Since the multiple snake springs are not connected to each other, or only the front or rear of the multiple snake springs have a reinforced connection structure, the strength of the middle of the snake spring is relatively low. When a heavy user sits in the middle of the sofa, it is difficult to form sufficient supporting force with only 1-2 separate snake springs as the main force points, and the snake springs are easily "collapsed", resulting in a poor sitting feel on the sofa.
[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content
