CHAIR ARM LEG DURABILITY TESTER

Sofa Seat and Back Testing Machine is to simulate normal functional use to determine the strength of the sofa structure by applying to various parts with loads or forces. Using certain shape and load modules, with specific form, frequency, respectively, repeating load seat, back and arm-rest . Each point has force sensor to show the pressure.

Products description :

The use of Chair Arm and Leg Durability Testing Machine to evaluate the ability of the chair to withstand stresses that occur as a result of repetitive loading that can be imposed on the armrest structure. Loading of this type is the result of using the armrests as a support when getting into or out of the chair.
