Carefully analyze the following advertisement: is it selling a complete chair or just a part of it, like an armrest, mechanism, footrest, etc.? It's important to scrutinize the context in which words are used: the mention of 'accoudoir', 'appuie-tête', or other parts does not automatically imply a complete chair. The words 'complet', 'avec visserie', etc., can refer to the sub-parts being complete or accompanied by their hardware, not necessarily indicating a complete chair. Also note that a higher price does not necessarily mean it's a complete chair. Start your response with 'Full chair' or 'Sub-part of a chair' and then provide a concise explanation based on the French advertisement. Here's the advertisement to consider:assise et mcanisme flintan pour pices je vends cette assise+dossier de sige de bureau ikea flintan avec son mcanisme car l'assise est devenue trop molle.
le mcanisme fonctionne bien. le dossier est en assez bon tat. l'assise est trop molle et tache.

...si ca peut arranger quelqu'un.
