Abstract
In this paper it will be presented the deformations analysis using the finite element analysing method, for an armchair seat redesigned from an wooden original model, into a polyurethane more compact structure. In order to perform the testing required, a 3D PU design was made after the wooden model. This new design was made in such way which will enhance the productivity, to be more compact, more lightweight and also more resistant than the original design.
