The purpose of this study was to explore and attempt to understand the experiences, along with the efforts and perceptions of those efforts, of teachers who implemented flexible seating during the COVID-19 pandemic. A semi-structured interview protocol was used and aligned with the theoretical framework, constructivist learning theory. Constructivist learning theory centers on learners constructing their own knowledge through the process of using their prior knowledge, which was applied when teachers were required to adjust their classroom protocols due to the COVID-19 requirements. This qualitative phenomenological study examined the following research questions: What are the experiences of elementary school teachers who were committed to the benefits of flexible seating and employed flexible seating strategies to in-person learners during COVID? What are the teachers' perceptions of the impact of flexible seating strategies employed with in-person learners during the COVID-19 pandemic? This research found that the participants underwent modifications to their flexible seating procedures in addition to having increased cleaning processes. The participants also perceived either an improved community experience in their classrooms or students began getting along better. Each participant also perceived a modification in student engagement in their classroom. Two participants noted an overall increase in engagement when they used flexible seating and three participants noted their students being both more engaged and less engaged at different times. This study contributed to the growing body of knowledge on flexible seating. It also provided insight to the teachers' process associated with implementation, along with the outcomes the participants experienced. This research was important because this information could help educational institutions prepare for future disruptions.
