Purpose - The purpose of this paper is to evaluate upholstery deformation by using resonant vibrations of separate zones of the soft part.Design methodology approach - By recording the value of resonant frequency at separate points of the plane, it becomes possible to obtain the graph of deformation distribution. It is compared to the graph that demonstrates how rigidity distributes itself in different directions within the upholstery fabric. This enables the evaluation of unevenness of upholstery deformation that is present in different directions.Findings - The provided methodology allows assessing the quality of soft furniture assembly and predicting the exploitation time for its upholstery.Originality value - The test results obtained using the original methodology enable the assessment of manufacturing defects existing in various directions (for example, the shape of different parts during the cutting process, the unevenness of seam width and others), as well as the quality of furniture during the production and exploitation process.
