✔ 最佳答案
Desks and chairs in a classroom are 'furniture', not equipment, not facilities either.
Having said that, if you insist to choose one from 'equipment' and 'facilities', I would say 'equipment' is marginally acceptable, though not desirable. Broadly speaking, 'furniture' can be considered some sort of 'equipment'.
Example: The classroom is equipped with desks, chairs, white board, projectors, computer and public addressers.
