ゲルクッション 椅子 尾てい骨 座布団 お尻が痛くならない 【極上の冷感 高密度ジェル】 オフィスチェアパッド 長時間座 穴あき U字型の凹み 人間工学設計 肌触り 滑り止め加工 蒸れない 抗菌防臭 カバー洗える ゲーミングチェア 車用 自宅 特大 厚め

カラー:ダークグレー 薄くて通気性の良いカバー(ハニカムメッシュ生地)
サイズ:長さ約46.5cm×幅約41cm×高さ約11cm

①【アップグレード高密度ゲル、極致冷感テクノロジー、熱伝導率2倍向上】 座面内部には冷感性能をアップグレードした高密度ゲルを採用。熱伝導率は従来の低反発ウレタンクッションと比較して約2倍。優れた熱伝導特性により、身体(特にお尻)で発生した熱を素早く皮膚表面から逃がし、接触面を通じてクッション内部に伝え、空気中へと放出します。体温を効率的に拡散し、お尻まわりの蒸れを大幅に軽減。夏の長時間着座でも涼しく快適な座り心地をキープし、「長時間座ると蒸れて汗ばむ」という悩みを解消します

②【3D人間工学、尾骨ゾーン正確な減圧、従来クッション比で圧力ピーク約35%低下】 ゲルクッションは、独自の「縦長楕円・拡大中空構造」を採用しています,着座時に尾骨が接触する部分を中空設計とすることで、尾骨やその周辺領域への直接的な圧迫を回避。同時に、人間工学に基づく3D立体サポート設計により、360度全方位の包み込みを実現。体重をお尻と太もも全体に均等に分散させます、自然に背筋を伸ばし、姿勢を改善。長時間座っても疲れにくい正しい姿勢へと導きます

③【二層複合内芯構造、10万回圧縮テスト合格、2年間使用後のへたり率5%未満】 座面の上部には、冷感性能をアップグレードした高密度ゲルを採用しています,高い放熱性と熱伝導性で効率的に冷却。下層にはへたりにくい高密度低反発メモリーフォームを採用。二層構造が衝撃を吸収し、体圧を分散。硬すぎず柔らかすぎない「絶妙なサポート力」を実現し、長時間座り続けても快適な座り心地が持続します

④【拡大中空放熱、通気性・耐摩耗性・瞬間冷却】 長径・通気性の中空設計をプラス、素早い放熱を実現。常に清涼でドライな肌触りをキープします。フルオープンジッパー設計によりカバーを完全に取り外せますので、
丸洗いが可能です。
