: The quality is really, really poor: 1. The mesh softened very quickly. 2. The plastic cracked after 2 years, and my home office has no direct sunlight. 3. In comparison, a no-name chair I bought at Costco for my other office has held up without any issues... 质量非常非常不好： 1. mesh很快就软了 2. 塑料2年后断裂，我的家庭办公室没有太阳直射 3. 对比之下我另外一个办公室costco买的无名椅子都hold一点问题没有……
