Case Study

Aftermarket Car & Truck Consoles

After police vehicles are retired, they are sold to the public through aftermarket channels and don’t include center consoles. Nenno Products saw an opportunity to fill this gap, offering aftermarket consoles with cup holders, storage, and a comfortable armrest.

But their previous manufacturer struggled with quality control and delivery delays. Looking for a better partner, Nenno turned to us. They were drawn by our proven upholstery capabilities—and the added benefit of reduced lead times and shipping costs thanks to our shared Midwest location.

Time to Get to Work

We kicked things off with a collaborative design process. Nenno brought deep industry insight and strong woodworking expertise. Our engineering team developed a custom manufacturing method to seamlessly wrap vinyl and padding around the wood structure—delivering clean edges, tight upholstery, and a noticeably higher level of quality.
