The HARVIA Onni Sienna Duo combines natural materials with advanced infrared technology, creating a comfortable and inviting environment for one or two users. Designed for everyday home wellness, the cabin delivers infrared warmth quickly without the need to preheat the entire cabin volume, allowing you to enjoy a relaxing session whenever you choose.
The exterior features an elegant mahogany finish that provides a warm and timeless appearance, while the interior combines mahogany and Hemlock wood for a harmonious and welcoming atmosphere. A large glass front enhances the sense of space and gives the cabin a modern, open look.
Each seating position is equipped with a dedicated full-spectrum infrared heater located behind the back. Additional carbon heating panels positioned on the sides, beneath the bench, and in the floor ensure balanced and evenly distributed warmth throughout the body. This combination creates a comfortable infrared experience with consistent heat from head to toe.
The cabin is controlled via a large 7-inch touchscreen display, allowing easy adjustment of temperature, lighting, and session settings. Integrated RGBW chromotherapy lighting and a Bluetooth audio system help create a personalized relaxation experience tailored to your preferences.
