Rugs are common additions to many hard surfaces including tiles and hardwood. They are designed to play a number of roles. Its very hard to imagine covering your shiny hardwood floor with an accent rug but its actually something worth considering. First, the grey and beige rug will reduce noise. This is because such a carpet is quieter to walk on compared to a hardwood floor or any other hard surface. Theres also some warmth and comfort that comes with grey and beige rugs.
