The room which first served as the parents' bedroom was converted into Sibelius's combined study and bedroom in 1942. The bedside table and the bed had originally been bought from the Stockmann department store for the apartment in Kammiokatu. In this bed Sibelius died on the evening of 20th September 1957. 

Behind the furnishings there is a washing alcove,

where Sibelius's razors, soaps and toothpastes are still kept. On the table on the right of the alcove there are the "Sibelius emblems", i.e. the composer's walking stick and his Italian-style broad-rimmed hat.

There is an antique chair in front of these that Aino Sibelius had inherited from her father, Alexander Järnefelt. On the shelf to the right of the window there is a metronome which the composer probably used in his old age, to give metronome indications to performers "in order to avoid the worst mistakes".

On the bookcase in the study there are many dictionaries, and the biography of Robert Kajanus by Yrjö Suomalainen. On the wall on the right hangs a 50th birthday present given to Sibelius by Eliel Saarinen (1873-1950). This is a plan for a monumental building called "Castle In The Air". To the right of Saarinen's plan is a watercolour of Aino by her brother Eero Järnefelt (1863-1937), painted in 1896. 

The desk and chair are said to be from the estate of Alexander Järnefelt. The desk can also be seen in a photograph of the upstairs study taken in 1915. Most of Sibelius's compositions were written at this desk.

Sibelius began to wear a white suit in the late 1930s, as can be seen in many photographs.
