A sectional couch is composed of multiple sections that are connected to form a single piece of furniture. These units generally include a sofa, a loveseat, and a chaise lounge, allowing you to create various seating arrangements to fit your needs.
In contrast, a modular couch consists of individual pieces that can be rearranged and reconfigured according to the user's preferences. This modular design offers flexibility, enabling you to add or remove sections as needed.

Belffin Tip:Why the Corner Piece Matters in a SectionalWhen we talk about sectional sofas, the corner piece often gets overlooked — but it’s one of the most functional and versatile parts of the entire design.
Not only does it connect the entire structure, it also becomes a natural conversation hub, a lounging spot, or even a mini home office nook. When planning your layout, don’t underestimate the comfort and flow a good corner piece can bring.
