1,795.00 SEK
The X50 from Axona AICHI is an innovative and stackable chair designed for modern conference rooms, training environments, and public spaces. With its ultra-lightweight construction, high comfort, and exceptional stacking capacity, the X50 combines functionality and durability in a minimalist design language.
Maximum stackability in ultra-lightweight design
The X50 is an intelligent stackable chair where comfort, durability and extreme flexibility meet in an ultra-light design. With exceptional stacking capacity, innovative materials and thoughtful features, it is the perfect choice for modern conference rooms, training environments and public spaces.
Sustainability & materials
X50 is developed with a focus on circular design and sustainable production. The seat and back are made from 100% recycled polypropylene combined with elastomeric materials that provide both flexibility and long durability. The design is also designed for easy disassembly and full recycling after the product’s lifetime.
The minimalist design minimizes material consumption without compromising on stability or comfort — a thoughtful choice for projects with high demands on both functionality and environmental responsibility.
Comfort & functionality
Despite its slim and lightweight design, the X50 offers very high seating comfort. The flexible back made of specially developed elastomeric material follows the body's movements and creates a comfortable and dynamic seating experience even during extended use.
The unique double-cast seat construction adapts to the body's pressure points and provides comfort comparable to upholstered chairs — while being significantly easier to clean and maintain.

Filter slide lists

Flexibility & applications
The X50 is designed for environments where flexibility and efficient handling are crucial. Thanks to the innovative frame design, the chair can be stacked up to 50 units on a transport trolley and up to 18 units directly on the floor, making it ideal for larger conference and training environments.
Several smart options are available, including armrests, a keyboard, connection brackets, and specially adapted transport carts for easy storage and logistics.
Design & expression
Designed by Taku Kumazawa, the X50 is characterized by a minimalist and technically elegant expression where every detail is carefully considered to combine aesthetics with functionality. The chair’s clean lines and ultra-thin profile make it a natural addition to modern work environments and public interiors.
The X50 has also been awarded several international design awards, including the Red Dot Design Award and the iF Design Award.
