Narrative:

While on a road trip; I removed passenger seats 10A and 11A; 17A; back course; and 18A; back course in order to readjust sidewall panels on aircraft. After readjustment of the sidewall panels; I reinstalled the passenger seats and mistakenly swapped position of seat 10A and 11A. Not knowing that I had done this; I continued with the follow on of the seat installation and had a quality assurance inspector rechk my work. Mr X was the inspector that evening. He signed the non routine work card and the job was closed. I didn't realize that I had switched the seat position until I was told that they had found them switched at XXX.
