The main objective of the completed tests and numerical analyses was to develop guidelines for improving the technical quality of massproduced upholstery frames. The paper describes the results of strength measurements of corner connections, corrugated spring holders and the permissible tension force of these corrugated springs. The experimental tests on the strength of the corner connections were performed for four variants of connection specimens. The tests investigated the strength of three different spring holders and the tension force of two versions of springs. The analysis of stiffness and strength of the entire frame was performed using the Finite Element Method (FEM), based on the data obtained during laboratory tests. Based on the results of the tested specimens of the corner connections, it was found as follows, in particular: 1) the value of the ultimate force on the staples in the connection has no significance for the strength of the connection (connection load capacity is determined by the load capacity of the adhesive-bonded joint; 2) the most advantageous structural variant of the spring holder was demonstrated; 3) the tension force of a single spring in the frame in the cases under consideration was in the range of 160-210 N which, during assembly, may temporarily reach 420 N. The dispersion of these force values is clearly different for springs from different manufacturers. Complementary numerical analyses have shown that the frame structure under analysis was rigid and durable, and as such it should not pose any risk during use.
