Grouping lounge furniture with yes armrests and plastic bases
Decide how the visitor lounge should communicate its seating arrangement. Individual places aligned along the room create a different pattern from seats turned toward one another. Use the armrest outlines to assess how clearly each place is defined, then review the visible plastic bases as part of the same group. The material description does not establish their shape or finish. Look at the actual furniture from the entrance to understand how the seating reads on arrival. A visitor should be able to distinguish the route through the room from the approach to a place.
Plan for people arriving together
Consider how a visitor joins someone who is already seated. Review the route to an adjacent place and the space where a brief standing conversation might occur before sitting. Armrests need to be included in these movements, particularly where a seat is beside a wall or at the end of a group. Check each approach with neighboring places occupied. If the room includes both individual and shared conversations, establish where those activities sit within the arrangement. The seating orientation should make the intended relationships understandable without depending entirely on the gaps between pieces.
