Customizable comfort. The Plis sofa is a modular unit that combines soft, linear shapes on the seats with ruched fabric across the broad backrests. The backrests can be heightadjusted for maximum comfort on any occasion. They are also fitted with an innovative extension mechanism developed by LAGO, which makes it easy to move from a lowback to a highback configuration. This means they can be adapted to different usage needs at different points during the day. At the simple press of a button, the backrest extends or retracts, thanks to an internal mechanism and specially worked upholstery, making it easy to personalise comfort.
