Flexible seating is equitable universal design. The nine principles guiding Universal Design for Instruction are: 1) equitable use, 2) flexibility in use, 3) simple and intuitive, 4) perceptible information, 5) tolerance for error, 6) low physical effort, 7) size and space for approach, 8) a community of learners, 9) instructional climate.
[Scott, Shaw, and McGuire, 2001]
First, remove your teacher desk or repurpose it. I turned mine into a coffee and snack station - the mini fridge went underneath and the microwave and Keurig went on top.
Second, determine how students will need to use the space.
Third, rearrange and then continually reassess. Get feedback from the students. Sit in all the areas of the classroom. Make changes and get new furniture as needed.

Know what your intentions for the space and groups are.
Choose different types of spaces - heights, seating, surfaces - for different purposes and outcomes.
Especially for younger students, create deliberate groupings rather than solely free choice.
Never be afraid to readjust the room arrangement - get feedback on it from your students.
In the photos above you see examples of intentionally purchased furniture for flexible seating, relocated furniture from a school district warehouse, and social media crowdsourced furniture.
