Introduction
The document presents the Orta chair series, designed by Christoph Hindermann in 1997, emphasizing its innovative use of materials and design versatility.

Design and Specifications
The Orta series is described as a multifaceted marvel, offering a range of models including stools and floor-mounted versions. These models can be combined for design continuity and feature a 360-degree swivel base that returns to the forward position when vacated. The chairs are available in both arm and armless versions.

Materials and Construction
The chairs are constructed with a steel framework, available in various finishes such as powder-coated dark or light aluminum, galvanized, and chrome-plated with a pearl-matt finish. The backrest is made from a flexible, breathable mesh material called Trevira, which is durable and easy to clean. The seat options include black nylon, plywood, or upholstered materials, with injection-molded polyamide for durability and UV resistance.

Color and Finish Options
Orta offers a wide range of customization with seven back colors, five frame finishes, and multiple seat options, allowing for endless design possibilities to match any decor.

Practical Features
The chairs are designed for convenient stacking, with the ability to stack ten high without arms and seven high with arms. A trolley is available for stacking up to 16 chairs for easy transport and storage. Ganging devices are available for connecting chairs in various configurations, and removable, magnet-based seat numbering is offered for event guidance.

Outdoor Use
The Orta series is suitable for outdoor use due to its weather-resistant materials, including a polyamide seat and a non-fading mesh back available in seven colors. The steel frame is galvanized and powder-coated for durability in outdoor environments.

Conclusion
The Orta chair series combines innovative design, material versatility, and practical features, making it suitable for a wide range of indoor and outdoor applications.
