## Customer Reviews

### ⭐⭐⭐⭐⭐ 今のところ不満なし
*by A***U on July 31, 2025*

しっかり梱包されており、やり過ぎぐらいです。ネジなどは1個予備が付いており、使わないが安心感があり、開封と組み立ては一人で1時間未満が、疲れてしまいました。座り心地は現時点で満足です。腰はしっかり支えており、メッシュのため通気性も良く、夏に最適です。耐久性はまだ不明が、3年保守もあるから、大丈夫と思います。後はもう少し安くなるともっと良いなと思います。

### ⭐⭐⭐⭐ 前の椅子より100倍マシ
*by V***3 on May 24, 2025*

まず大前提として前使ってた2万弱の椅子より100倍マシとしたところで不満を挙げるとすると・塗装のムラ？がある(足部分がざらざらする)・組み立てにめちゃくちゃ力が必要(これは筋力足りないやつが悪い)・キャスターが入らない(組み立て後に座れば重みで入ると見たが入らない(70キロ弱のオスです))それら不満を挙げた上で機能も多く、ココロオドル商品であり、腰も楽になりました。届くまではインフルエンサーが広告めっちゃ出してるから失敗(釣り商品)かなと思ってたけど使ってみる価値はありっすね。ありがとう謝謝

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Amazing Chair—Perfect for Long Hours of Work from Home!
*by A***ー on August 17, 2024*

I've been using the SIHOO S300 for a while now, and it has been a game changer for my work-from-home setup. Before getting this chair, I used to suffer from severe back and butt pain after sitting for long hours. This chair has completely resolved those issues. The ergonomic design provides excellent support for my back, and the seat is comfortable enough to sit on for extended periods without any discomfort.One of the best parts is that I was able to customize it to fit my needs even further. I added a mouse and keyboard attachment directly to the chair, which has made my workspace even more efficient and comfortable. I highly recommend SIHOO to consider making this a standard or optional feature, as it adds incredible value to an already fantastic chair.If you're looking for a chair that provides great comfort, especially for long working hours, this is definitely the one to go for!
