Review: 座り心地がよく、丈夫。 背中部分を微調整する必要があったり、組み立てが大変だったりはした。
Review: ※参考までに。レビュアーは身長180cm、体重70kgの男性です。 ①組み立て ★★★☆☆ 専用の工具等を使わずに一人で組み立てることが出来ました。説明書も難しくなく、部品の数も多くないので間違いにくいと思います。所要時間は30分と少し。しかし各部品がそこそこ重いので、力の弱い女性や子供は誰かに固定してもらいながら組み立てるのが吉。 ②見た目 ★★★☆☆ 新品なので当然ですが、到着時点で汚れや傷はなし。商品写真では分かりにくいかもしれませんが、グレーのメッシュに謎の模様が入っています。骨組みのプラスチック部分はちょっと高級感に欠ける印象。 ③使用感 ★★★★★ 通気性のいいメッシュ素材のため蒸れはほとんど無く、快適に座っていられます。背もたれは3段階固定と固定なしを切り替え可能です。肘置きがもう少し長ければ良いなと思いますが、個人的に座り心地には満足しています。 ただし、結構大きい椅子なのでデスク周りにそこそこのスペースが必要なこと、もしかしたら小柄な方は身体に馴染まないかもしれないことには注意が必要です。 ④総評 ★★★★☆ 概ね満足。しかしまだ1ヶ月程度しか使用していないため、座面のメッシュの耐久性などは不明。長持ちしてくれたら嬉しいです。

*by T***2 on June 27, 2025*

座面や背面ののメッシュは、暑い日もベタつかず快適です。 デザインも今っぽくて、選んだグレーは明るい色でした。 部屋が明るくなりました、とても満足しています。 ヘッドレストは外しても使えるので、今は外して使用しています。 この椅子のおかげでデスクまわりが広々して感じるようになりました。 組み立ては15分程度で容易でした。当方、170センチ、65キロの男性です。 付属の工具とネジは１枚のシートに綺麗にレイアウトされ、パウチされているので一覧して見やすいです。T型の持ち手のついた六角レンチは力も入れやすく、ネジは3種類しかないので間違えることも少ないなと思いました。組み立ての際に手を保護する軍手も付属しています。 足とロッキングユニットのみスチールという部材による重量配分でしょうか、座った感じは見た目よりどっしりと安定しています。 配達されてきたときの梱包も無駄がなく、発泡スチロールなどの過剰な緩衝材などもなく、適切でゴミも最小限でよかったです。 ※写真を添付しておきますので、興味のある方はご覧ください。
