Since 1845, the Red Room has been a parlor filled with crimson furniture. Before this, though, the room was actually used as a meeting room for President Thomas Jefferson. Jefferson's office at the time was located where the State Dining Room is today — so the Red Room was in close proximity and ideal for meetings. It has become a parlor that first ladies often consider to be their favorite. They have used it throughout history as a "private parlor" to host friends and other guests.
