The seam fatigue tester is a useful tool for evaluating the failure of the three most commonly used upholstery seams, namely warp sewn to warp (wale to wale), filling sewn to filling (course to course), and warp sewn to filling (wale to course). The stress is imposed at the seam and fatigues the seam.
