About Work System


We develop and sell vehicle racking systems for vans and other service vehicles. Most of our solutions are locally produced in the Småland region of Sweden. Småland is not only a well known Swedish holiday destination and setting for Astrid Lindgren's books but also well known for its people's entrepreneurial drive and for being a centre for innovative entrepreneurship. The opportunities to cooperate with suppliers locally contributed largely to our company's success.

In Småland we found everything we needed to successfully start our own business. Our families and friends spent many nights with us working on our ideas and we are eternally grateful for their support. Right now, we have 50 amazing employees who focus all their energies to fill our Work System dream with life and provide our customers with great products and great service.


With its innovative product development and cutting-edge production methods, Work System offers its customers smart racking system solutions for their vehicles at competitive prices.
As our customers' needs differ, we have developed a modular range of racking solutions which can satisfy all types of customer requirements. Our systems belong to the most flexible of its kind in Europe. All shelves are designed in a modular manner which means they can be adapted to your needs. Additionally, Work System solutions can be flexibly extended due their modularity. Thus, you do not have to buy everything at once. Should you for instance need an additional drawer unit in the future this can be easily added to your existing racking system.


Quality matters to us. We listen to our customers' feedback and our racking systems are regularly tested and improved. We use state-of-the-art simulation techniques and send critical parts of our product range to the SP Technical Research Institute of Sweden for crash testing.

The materials we use in production are mostly processed by robots which ensures high precision and lower production costs. All drawers run on ball-bearing rails which mean they can also be operated smoothly when heavily loaded.

We are confident that our products will serve your needs and are happy to offer you a free 36 months guarantee on our whole range of vehicle racking systems (terms and conditions apply).


For most of our customers the most effective use of their van's loading capacity and working time are the two major factors influencing their buying decision. However, many forget the most important factor - safety. Securing all materials and tools safely in your car protects not just you but also others whilst driving your vehicle. Check out our product videos to see what might happen if cargo is not safely secured during a collision.
