Review: Got this to replace my damaged Aeron Re-mastered. Although it's description was for Aeron Classic, it was a perfect fit for the Re-mastered. Easy to replace with all the necessary tools provided. A quality replacement.
Review: La instalación se realizó muy rápido con la herramienta incluida, debo decir que se siente mas resistente que el asiento que tenia originalmente mi aeron(el cual terminó por tener grietas y posteriormente romperse). Lo recomiendo aunque el precio no es muy bajo que digamos, espero dure bastante para darle mas años de vida a mi aeron.

座面が破れたため購入して取り付けました。 座り心地は良いです。 交換作業時間は男一人で30分弱でした。 工具や説明書のようなものは付属していませんでしたので注意してください。 品質は問題なさそうに思えますが問題はこれからどの程度の期間使用に耐えるのか。 今のところは満足しています。
