Buying a set ensures a cohesive look in terms of color, fabric, and style. If you prefer a uniform design, a matching set is a great choice.
Purchasing a set is often cheaper than buying individual pieces separately. Retailers may offer discounts for bundled furniture.
Do you have enough room for both pieces? Measure your space to ensure they fit comfortably without overcrowding. If your room is small, an armchair alone might suffice, or you could opt for a love seat instead of a full sofa. Mixing and matching different pieces can add character to your space. If you enjoy eclectic or layered designs, buying separately might be better, Test both the sofa and armchair for comfort. Just because they look good together doesn't mean they're equally comfortable.If you move frequently, a modular or separate setup might be easier to transport than a bulky set.
