The story of ST Inventar
Our history dates back to 1949, when Christian Søndermark founded Søndermarks Møbelfabrik in Tarm. The idea was then to produce tables and chairs for schools in wood.
Just three years later, the production of fixed furniture began, and from here the development accelerated. With a particular focus on subject rooms, strong competencies, and an extensive reference list, we are today the market leader in total solutions for education.
We continue to work on developing the best interior design solutions for the education sector, and today ST Skoleinventar is also represented in schools in Norway and England.
1950 - Søndermarks Møbelfabrik is founded by Christian Søndermark.
1955 - School furniture and school inventory become the primary focus, which we assemble ourselves in school kitchens, physics rooms, woodworking rooms, teachers' rooms, etc.
1963 - The existing factory had become too small after significant development. A new factory was built covering 1,600 m2.
1973 - Founder Chr. Søndermark stops, and son-in-law Mogens Jørgensen, who had been involved since 1953, takes over.
1983 - New director, and later co-owner, Knud Pedersen, joins.
1993 - The company name is sold to a trading joint-stock company consisting of four employees: Knud Pedersen, Knud Erik Strandbæk, Aksel Poulsen, and Bent Nielsen. This trading joint-stock company then purchased goods from the production company operated by Mogens Jørgensen.
1994 - The four co-owners also take over production. Sales assistants Kim Dengsø Nielsen, Tarm, and Christen Jespersen, Lystrup, become co-owners as Bent Nielsen retires, and Knud Erik Nielsen has sold his share.
2003 - ST Skoleinventar becomes part of Continental Investment Company A/S but continues to operate as an independent company.
2008 – ST Skoleinventar strengthens its position in the market through partnerships with architects and general contractors. The focus is on integrating inventory as an active part of the building's overall learning strategy rather than just a delivery.
2014 – Increased focus on sustainability and total economy. ST develops solutions with long lifespans and low maintenance, reducing operating costs for customers.
2018 – ST expands its portfolio to also include specially designed solutions for nursing homes and colleges – with a focus on safety, ergonomics, and flexibility.
2021 – Sustainability becomes a central strategic focus. ST works purposefully with material selection, certifications
2023 – ST positions itself as a total supplier of furniture environments – from idea and concept development to production, delivery, and assembly.
2026 – ST changes its name from ST Skoleinventar to ST Inventar. Our DNA remains quality and customized solutions. The name change reflects our development, our innovative power, and the growth we are already underway with. We strengthen our position – and open the door to new and broader collaborations.
