## Description

A 9" (230mm) black replacement gas lift for office chair.

Review: Ya estaba pensando en renovar mi sillón de director por uno nuevo, ya que el pistón no aguantaba y se bajaba constantemente, y me daba mucha rabia porque el sillón sólo tenía un año y medio y lo tenía bastante cuidado... pero entonces descubrí que BiMi vendía el pistón por separado y eso ha sido mi salvación... ahora mi sillón vuelve a funcionar perfectamente y lo puedo aprovechar algún tiempo más... y lo más importante, habiendo gastado poco dinero en comparación con lo que cuesta un sillón nuevo... así que estoy muy contento... Montarlo es muy sencillo... pero lo más difícil es desmontar el viejo, que suele estar bastante encajado en la base y en la plataforma de la palanca... pero se consigue con un poco de maña y de paciencia... además hay algunos vídeos por la red que te explican cómo hacerlo... ;-)

Mi riservo di darne una valutazione maggiormente esaustiva in futuro, ma credo di poter dire qualcosa di utile già ora. Prima di tutto: mi ha colpito la serietà del venditore! Neanche due ore dopo aver ordinato il pistone (che avevo chiesto mi fosse consegnato sul posto di lavoro), ho ricevuto una chiamata in ufficio da parte del venditore. Mi hanno fornito un numero di telefono a cui mandare, via WhatsApp, delle foto della sedia, così da essere sicuri di spedirmi il pezzo corretto. Meno di 24 ore dopo l'ordine, il pistone mi è stato recapitato, ed era perfetto. Al momento, nulla da dire sul funzionamento. Non che lo usi molto, ma mantiene la sedia all'altezza desiderata, mentre il vecchio cedeva di continuo.
