OfficeBusters Corp. (Headquarters: Higashi-Ote Building, 1-1-7 Uchikanda, Chiyoda-ku, Tokyo; President: Masayoshi Kumagai; Tokyo Stock Exchange TOKYO PRO Market, Securities Code: 5890) has released the top 5 list of used office chairs purchased by individual customers in May 2026. Following the previous month, May continued to see high levels of consultation regarding the refinement of work-from-home and telework environments, as well as the selection of ergonomic chairs for prolonged home use. Consequently, the rankings were dominated by high-end series that offer comfort, functionality, and aesthetic appeal—models that are difficult to afford when purchased new but are accessible when bought secondhand. As with the previous month, individual users prioritized features such as "comfort during long hours of sitting," "ease of adjustment to fit physique and posture," and "satisfaction with the visual impact on the home space." (Survey period: May 1, 2026 – May 31, 2026, based on company sales data.)
