電動升降桌
電動升降桌 – 喺香港，隨著人們的工作時間越來越長，我地對辦公室傢俬的要求也要不斷作出檢討。因為 20-30 年前大家工作的環境及習慣跟現在比起實在有了不少的差別，以前合用的傢俱現在可能已變得不太符合人體工學。久而久之，如長期使用不太符合人體工學的傢俱，用家因此而受傷或引起痛症的機會亦大大增加。最近三四年美國開始流行電動升降桌這個新辦公室設備，且被科技界廣泛接納，由其矽谷那班常常對著電腦日以繼夜的一羣精英，可以企喺度做野令到其中不少有腰背痛一族者趨之若鶩。 
查實企喺度做野的而且確是有很多好處的。根據很多外國的科學研究指出，長期坐下對人體健康有多方面的壞處。以下是一些關於久坐跟危疾方面的研究報告重點撮要，專家們亦簡稱為久坐疾病（sitting disease): 2013 年美國醫學協會（American Medical Association) 指出久坐引起的健康問題並鼓勵僱主、僱員及其他人仕改用可拱坐或企的電動升降桌（standing desk） 2011年Centers for Disease Control and Prevention(疾控中心）指出使用電動升降桌的用家較少有背痛等疾病並讓其提高工作情緒 2010年 American Cancer Society (美國癌症學會) 撰文提出閒時坐得較多的人仕患病機會增加而且壽命一般較短 2009年 澳洲昆士蘭大學（University of Queensland) 研究顯示成人就算有正常活動者，久坐亦會減慢身陳代謝 如何選擇電動升降桌 當你已經考慮買一張電動升降桌的時候，以下有幾點不妨參考下： 一、一般電動升降桌是用摩打去控制枱面的上落速度，由每秒 16mm 到每秒 35mm 不等。速度快慢對健康問題不大，但當然快一點對欠缺耐性的人一定較適合 二、電動升降桌枱面的總高度：一般電動升降桌可以升至1200mm即大概4尺左右，所以就算各下身高六尺問題亦不大。最低的一般可以到 600mm, 其實亦頗適合小朋友了。但要注意每個供應商這方面會有多少出入。 三、桌面：一般電動升降桌可讓用家選擇三幾種不同顏色。在這方面 Ergoseatings.com 希望作出一點突破。我們可以任由用戶自訂桌面形狀、大小、顏色、物料(防火板甚至實木）、桌面開孔多寡或尺寸，甚至需要加桌櫃均可。 四、其他配件。要配合一張電動辦公桌並使其符合一體工學，用家亦可考慮添置配件如 keyboard tray (鍵盤架）、CPU架或電線糟。在外國亦甚流行在電動升降桌下面配上 treadmill 跑步機： 用戶可以一邊工作一邊燃燒更多卡路里。 
以下列表包括由 2008 至 2014 年的多個綜合關於久坐及使用電動升降桌的研究報告:

後記 隨著香港人越來越注重健康，使用電動升降桌應該是一股不會減弱的大趨勢。雖然電動升降桌價錢比一般書桌的價錢稍高，但是如果可以讓用家減少疾病或肥胖的機會，仍然是值得考慮使用的。由其久坐對著電腦工作的人仕，保持脊椎及背部活動是非常重要的，一張好的人體工學椅可以説並不足夠。不過，根據一些美國早以開始使用電動升降桌的用家反映，雖然企喺度的而且確能大大減低腰背痛的煩惱，但要注意的是：長時間企喺度亦會有令腳跟腫脹的問題，所以使用者必須好好利用電動升降桌，時而坐下，時而企下，咁樣先可確保真正健康。
