Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a sofa with an elastic structure that prevents the sofa cover from falling off. Background Technology

[0002] Sofas, as an indispensable piece of furniture in modern homes, are mainly used for sitting and resting. Their structure usually consists of a frame, filling, and outer fabric (such as cloth, leather, etc.). Depending on their function, sofas can be divided into ordinary sofas and functional sofas (such as those with adjustable backrests and storage space). In terms of style, there are also various designs such as modern, classic, and minimalist, which can meet the decoration needs of different home environments. As the core furniture in places such as living rooms and offices, sofas not only provide a comfortable resting experience, but also have both aesthetic appeal and practicality.

[0003] In practical use, many users choose to add sofa covers to their sofas, which not only protect the sofa fabric but also enhance the decorative effect by changing different styles. However, most common sofa covers currently rely on simple slip-on methods for fixation, which are prone to shifting or loosening during use, affecting aesthetics and user experience. Although some products use Velcro or zippers for reinforcement, there are still obvious shortcomings: Velcro has limited adhesive strength and is prone to wear and failure after long-term use; while zipper structures may lead to inconvenience in adjusting tightness and are also more cumbersome to install. Therefore, improvements are needed to enhance the practicality of sofa covers. Utility Model Content
