The late Art Nouveau corner cabinets in the small dining room were originally designed by W.G. Palmqvist and Einar Sjöström (1882–1923) for Amos’s home in Helsinki. They were probably moved to Söderlångvik in the 1930s. The chest, featuring decorative iron fittings, dates back to the early 18th century. The bracket legs are a later addition. The Gustavian style dining chairs were made around the turn of the 20th century. The small mirror is from the late Gustavian period. The blue and white dinner service was made by the Danish manufacturer Bing & Gröndahl in the late 19th century.
