Lena with MDD

A mono-shell chair system for high-density stacking and versatile configurations.

Create a stylish, stackable chair system that adapts to conference, learning and contract spaces with visual simplicity and modular potential.

Lena blends soft geometry and stackability with modular options like armrests, pads and tablets. One structure, many contexts.

Featured on international platforms, Lena positions MDD as a go-to for smart, space-efficient seating in professional interiors.

A seamless blend of scalability and style

MDD needed a chair that combined superstackability with a strong visual identity and cross-market adaptability. The challenge was to create a mono-shell seating system that balanced comfort, functionality and scalability without looking generic. It had to stack high, ship compact, and scale easily for commercial, institutional and home use.

A universal chair for every context

Lena is defined by a two-piece polypropylene shell, clean lines and soft geometry. It stacks up to 40 units on a trolley and supports multiple options, including armrests, upholstered pads, writing tablets and varied base types. With its compact scale, minimalist structure and flexibility, Lena becomes a coherent system that adapts to different environments without losing identity.

Quiet design, global reach

The Mass chair has been well-received by customers and industry professionals, and is being considered for prestigious design awards with its recognition pending.
