Use Grey Bases as a Defined Reference
Grey plastic base office chairs should be represented by an agreed sample rather than a colour name alone. Compare that sample with the principal floor and desk finishes in each room. Note where the relationship is accepted and where it requires further discussion. If several grey surfaces are present, decide which one matters most to the seating scheme instead of expecting every surface to match. Inspect the base under the lighting normally used in the space. This produces a practical colour reference that colleagues can revisit without assuming that grey describes a single shade or a particular surface treatment.
Make a Comparison Record Across Rooms
A room comparison record can keep material consistency from obscuring differences in use. For each setting, list the desk arrangement, user group, floor surface and any nearby furniture that affects movement. Add the agreed base appearance separately from the chair's functional requirements. When comparing office chairs, this makes it easier to see which questions apply everywhere and which belong to one location. A compact workstation may need a different clearance assessment from an open desk area, even if both use the same base colour. Retain the room context so later changes can be reviewed against the original reasoning.
