Ristomatti Ratia has created a wide array of products. Many of these have become familiar classics, such as the Marimekko 301- shoulder bag and the Palaset- storage line.
Interiors are often the starting point for product design. Indeed, Ratia considers interior design to be the his own area. From 1998, the design work has been focused under his own Ristomatti Ratia- trademark. Ratia Brand Co., represents the trademark and designs primarily interior decorating products and clothing for various corporate clients. These products reflect the Ratia Lifestyle, which is characterised by good design, an air of freshness and casual elegance.
