Operating Instructions
The Shintenchi Convertible Sectional Sofa Couch features a reversible chaise design, allowing for flexible arrangement to suit your living space.
Reversible Chaise Configuration
The ottoman component can be moved to either the left or right side of the sofa to create a chaise lounge. Simply position the ottoman against the desired end of the sofa to extend the seating area. This allows for various layouts, including a traditional L-shape or a longer sofa with a separate ottoman.

General Care
- Rotate and fluff cushions periodically to maintain their shape and extend their lifespan.
