Overview:
This document provides detailed technical specifications and design parameters for the "roro" seating systems, originally designed by Roland Meyer-Brühl since 1998. It covers multiple models including the 2m2Ds soft, small, and medium versions, as well as various modular components and combinations.

1. Product Models and Seat Heights

• 2m2Ds soft: Seat height 45 cm
• 2m2Ds small: Seat height 43 cm
• 2m2Ds medium: Seat height 43 cm

The seat height is a critical ergonomic parameter consistent across models, with slight variations depending on the version.

2. Dimensional Specifications

The document lists extensive measurements for individual components and their combinations, including width, depth, and height ranges. Key dimensions include:

• Component widths such as 75 cm, 88 cm, 115 cm, 150 cm
• Depth ranges typically between 90 cm and 270 cm depending on configuration
• Height ranges from approximately 82 cm to 189 cm for various parts

Examples of component combinations and their overall dimensions are provided, such as:

• 2mDs l + Lc 88 r: 236-261 cm width, 162-226 cm depth
• Lc 88 l + Ze 150 + Lc 88 r: up to 326 cm width, 164-226 cm depth
• Eas l + 2mDs r: 261-346 cm width, 186-270 cm depth

3. Modular Components and Nomenclature

The document references multiple modular elements identified by codes such as:

• 2mDs l / 2mDs r (left/right modules)
• Lc 88 l / Lc 115 r (left/right modules with specific widths)
• Eas l / Eas r (left/right modules)
• Ze 75 / Ze 150 (modules with specific widths)
• 1 Mfs l / 1 Mfs r (single modules left/right)

These modules can be combined in various configurations to create seating arrangements with specific dimensional requirements.

4. Design and Ergonomics

The seating systems emphasize ergonomic design with adjustable dimensions to accommodate different user needs. Seat heights and widths are standardized for comfort, while modularity allows customization.

5. Key Parameters and Recommendations

• Seat height is consistently maintained at 43 cm or 45 cm depending on the model.
• Width and depth ranges are provided to guide configuration choices.
• Modular combinations are detailed with exact dimensional ranges to ensure fit and comfort.
• Design by Roland Meyer-Brühl ensures consistency and quality since 1998.

6. Summary of Critical Dimensions

Note: The document contains numerous specific measurements for various configurations, enabling precise planning and customization of seating arrangements.

7. Design Attribution

All designs are attributed to Roland Meyer-Brühl, emphasizing the original and consistent design philosophy since 1998.
