Mocked for being seated differently (6)
I believe the answer is:
teased
'mocked' is the definition.
(teasing is a kind of mocking)
'seated differently' is the wordplay.
'differently' indicates an anagram.
'seated' anagrammed gives 'TEASED'.
'for being' is the link.
(Other definitions for teased that I've seen before include "Needled in sedate way" , "Tantalised or annoyed goodnaturedly" , "Baited or bantered" , "Tantalized" , "Kidded in sedate manner" .)
