Most listings state adult assembly is required. Some models include assembly tools while others do not. Large modular sectionals often ship in multiple boxes—for example, one model is divided into three separate boxes—so be prepared for on-site assembly and multiple packages.
Care instructions vary by model: many indoor and outdoor listings recommend spot or wipe cleaning, some advise professional cleaning, and several outdoor sets or sectionals list removable, washable cushion covers.
Sectionals often offer modular, reconfigurable components and reversible ottomans for flexible layouts. Other convenience features in the listings include hidden storage, armrest organizers, and built-in power outlets or USB ports for charging.
