Whether it's the small-sized living room that requires "space-saving models", or the large-sized one that pursues "home theater-level combinations", or the temporary need for a sofa bed to accommodate guests' overnight stays, all these can be met by adjusting the combination methods. This completely breaks the limitation of the traditional sofa's "fixed form". It comes with clear and understandable assembly instructions. Without the need for professional tools, ordinary people can operate independently. And the assembly time is short, taking less than ten minutes to complete. This avoids the pain points of traditional large furniture such as "difficult assembly and long time consumption".
