Viewing a rug in a showroom is useful, but the final decision is often made in the room. Timber, stone, upholstery, daylight and ceiling height all change the way a piece feels.
What to look for
Check the rug from multiple angles, with lights on and off, and against the furniture that will remain in the room.
For collector pieces
High-value rugs should be considered for both beauty and long-term suitability: scale, wear patterns, placement and maintenance all matter.
