Among historical and art exhibits there is also a room devoted to the middle-class. This part of exhibition shows the miniature interior of a living room and a "buffet" part. The exposition equipment consists of furniture and tools for everyday use coming from Kęty houses.
The living room part is in an arched recess. The main element of the equipment is the 19th century set of furniture with brocade upholstery and sculpted arms. One can see there the portrait of the Kęty mayor Antoni Hałatek (painted by Józef Pochwalski, from 1927), a plaster bust of the priest Jan Dzierżoń from the beginning of the 20th century. There are also decorative materials from the period between the two World Wars: a tapestried wall, tablecloths, musical instruments: a mandolin and many other house trinkets dating from the 19th and the first half of the 20th centuries. It is also interesting to see the items connected with travelling like a leather bag, a hat box and a man's travelling dressing table.
On the opposite side one can find a wooden buffet where items for everyday use are on display. For example, there are the crockery from Ćmielów, the set of cutlery in the casket, glass and faience dishes, the typewriter, the wooden abacus and photographs of the Kęty middle-class people from the turn of the 19th and 20th centuries. In this part of the museum there are also other middle-class house equipment: a coal fire so called "Koza", a rocking horse with its head sculpted by Stanisław Jarząbek (about 1900), an engine made by Tadeusz Matusiak in the prisoner of war camp during the Second World War and finally, a wicker pram from the end of the 19th century. On the walls one can notice the paintings and oil pressures carrying a sacral meaning and house stoups very often appearing in former homesteads.
