Prostoria, formerly known as Kvadra, has established its position of a leader and promoter of new, innovative ideas in furniture production from scratch in a short time.

Since its earliest days, the company has focused on integration, cooperation and exchange of experience between all parties involved in the product development process. The vibrant atmosphere and cooperation enliven, boost and improve the furniture-making process. Due to this approach, designers grow with the company, based on mutual trust and shared goals. Although the brand's product catalogue includes office furniture with design based on well-tried models, Prostoria focuses strongly on innovative projects based on its own research. Prostoria primarily uses locally sourced raw materials (especially wood) to produce its furniture. Most products are manufactured directly on-site or in collaboration with local businesses.
