In this thesis we investigated the use of corner joints for furniture that will be used in boats and motor homes, analysing their advantages and disadvantages. The most common corner joints in boats are mortise and tenon joints, in motor homes they are coupling joints, while in standard home furniture they are eccentric joints. The joints were tested for tensile and compressive bending strength. The most common materials used in actual production were used in the study. The highest forces were borne by the joints used for boats. The corner joints for motor homes made of plywood had better results than joints made out of a modern composite material. Joints for home use carried higher loads than those for motor homes and boats. All the joints retained their shape after testing, except those made of a modern composite material, which loosened. Load simulations in SolidWorks partly confirmed the results of the testing and correctly predicted areas of increased stress and potential points of fracture. Because of the simplified boundary conditions used in the simulations, they were not accurate in predicting vertical displacements.
