Seifert was the first all-around gymnast from Switzerland to win a world championship medal since 1950. The last Swiss to do so were Walter Lehmann and Marcel Adette. The duo even snatched all-around gold (Lehmann) and silver at the home World Championships in Basel.

At the highlight of the season, Seifert managed to“rehabilitate” for the European Championships in Leipzig in May, when he was the best gymnast in the qualification for the all-around final, but ultimately came in sixth. He missed out on bronze on his dismount from the last apparatus.

In Indonesia's capital Jakarta, Seifert achieved the top score of all 24 finalists on the pommel horse (14.000). He also recorded the second-best score on the floor with 13.866 points behind the eventual winner Daiki Hashimoto. Seifert's weakest performance was on vault with 13.733 points, which was still the twelfth best score.

One week before his 27th birthday, Seifert delivered an exceptionally high level competition. He did not make any major mistakes on the six apparatus. He only slipped up slightly on his dismount from the rings.
