Looks like the seats from 5358 are now in 5486. Dan confirmed it on his twitter:
The seats from 5358 are now in 5486 (ex-GSC Citaro in non-standard trim), while the seats from 5486 have been re-cushioned and re-trimmed for 5358.

Have 8339 - 8343 been fitted with Wi-Fi and ‘next stop’ audio-visual announcements yet?
