Something so battle-tested it stopped being impressive and started being furniture.

means A person or thing that has been through so many campaigns, performances, or seasons of use that it's now valued mainly for reliability rather than excitement — the old reliable that gets wheeled out one more time.

from Literally, a warhorse was a large, sturdy horse bred and trained to carry a knight or soldier into battle — unfazed by noise, chaos, and blood, prized for steadiness under fire. By the 1800s the word had galloped into figurative use for anything battle-hardened by repetition: a veteran politician, a much-performed opera (Carmen and the like are classic 'warhorses' of the repertoire), or a reliable old machine. The shift tracks the animal's own fate — from frontline glory to dependable, slightly unglamorous workhorse.
