Abstract: The paper presents a comparative study of five, highly rated office chairs considering the ergonomic, structural construction, functionality, body pressure distribution aspects. During the investigation adjustability to the users dimensions, the physiological advantages of the postures the chairs provide, the comfort of sitting, the quality of execution were considered also. The compared chairs provided diverse sitting postures focusing on certain comfort aspects from elastic support (Aeron) to active seating (Spinalis), from balancing structure (Thatsit) to upright seating position (Salli) and posture monitoring (Axia Smart). The structural analysis of the chairs revealed the significant differences in adjustability, there were chairs with very complex structure, multiple adjustable parts, while others showed a simple but efficient construction. The results of the body pressure distribution analysis demonstrated the differences in peak pressures, contact areas between chair types, seating postures and  subjects body build.
