What does a Convertible Sofa Bedspring Tester do?
Repairs assembly and operational defects in convertible-sofa bedsprings preparatory to framing and upholstering: Examines unit for missing parts, and tightens loose rivets with pneumatic riveting gun. Places mattress in unit, pulls unit open and pushes it closed to test ease of operation. Adjusts pivot bolts and straightens connecting rods and brackets, using handtools. Rubs rough surfaces and joints with thinner and solvent to remove excess paint and grease and minimize friction.
