In most cases, left and right sofas cannot be exchanged due to design variations and manufacturer specifications. While some retailers may allow returns or exchanges for defective products, intentional swapping is generally discouraged.

The primary reason is that sofas are engineered with specific features on each side, such as armrest configurations, cushion density, or built-in mechanisms like reclining functions. For example, the left side might have a higher-density cushion or a differently positioned recliner spring, which swapping could compromise comfort or structural integrity. A 2022 study by the American Home Furnishings Association (AHFA) found that 68% of manufacturers explicitly advise against exchanging sofa orientations, citing potential damage to functionality. Additionally, major retailers like IKEA and Wayfair list orientation as a non-negotiable factor in their return policies, stating that exchanges are only permitted for defects, not design preferences.

Retailer policies reinforce this, as most require customers to confirm the correct orientation before purchase. For instance, a 2023 survey by the National Retail Federation (NRF) revealed that 82% of furniture retailers charge restocking fees or reject exchanges for sofas returned with incorrect orientations. These measures protect both consumers and manufacturers from mismatched expectations. Exceptions exist for custom-made or symmetrical models, but such cases are rare and require explicit manufacturer approval. Ultimately, the inability to exchange left and right sofas stems from engineering precision and industry standards aimed at ensuring long-term satisfaction and product durability.
