Chairbases Series London_345

With the series London_345 we present elegant base crosses in different variations, which can be integrated into numerous furniture projects due to their clear design.

We quote the modern architecture with the styling, because calculation bases from bridge construction and intelligent FEM analysis methods have shaped the design and optimised the production. London offers base crosses made of solid aluminium, which we produce in a sustainable and resource-conserving way with 30% savings in energy and raw materials. 

Functional office and conference chairs, but also contemporary lounge furniture are the home of this series, which is available in 3, 4 and 5-foot versions in numerous dimensions.

LONDON_345 is an aluminium base cross series with geometric, almost sculptural

styling. The series consists of harmonious variations of the five-leg base cross for office swivel chairs, four legs for conference chairs and three legs for lounge furniture.

Usually, base crosses are thin-walled with an internal ribbed structure and an open underside. proroll pursued the goal of developing a solid base cross that was also closed on its underside - the decisive factor here was to achieve this without additional materials. For the derivation of the highly innovative 4-legged and even more the 3-legged version, proroll went new a new road. The architectural challenge of achieving the same load-bearing capacity with only three legs as with five could not be achieved in the classic way.

LONDON_345 is the first new base cross series to be developed entirely by computer simulation. A calculation methodology was used, which is usually used for the construction of bridges. The result of this mathematically functional, and thus clearly structured, and objective history of development is a new type of base cross series with a clear design.
