During takeoff the First Officer's seat moved aft several detents after he introduced Takeoff Go Around (TOGA) (Flex) thrust and the engines spooled up. As a result of his seat moving backwards; the thrust levers came out of TOGA into the climb detent. After acknowledging the issue we quickly transferred controls; and I pushed the thrust levers back into the TOGA detent. We elected to continue rather than perform a high speed rejected takeoff. After the after takeoff checklist was completed; the First Officer was able to determine that his seat position adjustment lever had not fully engaged into one of the detented positions; but he was able to push the lever down and thereby lock the seat into a detented position. We chose to continue to our destination and called maintenance about the issue upon arrival.
[Report narrative contained no additional information.]
First Officer's seat slid back during first part of takeoff roll. Throttles came briefly out of Takeoff Go Around (TOGA) settings; but were quickly re-set.
