Bridger, Robert S(1988)在「探討傾斜的桌面和椅面對坐姿的影響」研究中,請受試者在四種不同的桌椅組合(桌面有無傾斜、椅面有無傾斜)下進行寫字,同時透過攝影機從正右側面觀察受試者的姿勢變化。結果發現,在有傾斜角度的桌椅組合中,受試者不但減少頸部屈曲的變化,同時也能維持較直立的軀幹姿勢。所以他認為具有傾斜角度特性的桌椅,對學生而言是較適當的。
Sam Murphy(2004)在探討有關學童坐姿對發生下背痛的關聯性研究,他觀察了66名年齡介於11~14歲間的學童在水平桌面和傾斜桌面的學習情形,結果發現,當學童坐在水平桌面時會有較明顯的身軀彎曲角度,而他認為此現象和學童發生下背痛的原因有很高的相關。因此他也對學校的相關主管和課桌椅設計廠商提出呼籲,務必重視桌面對學童的生理影響,而不是只有桌高、椅高符合條件即可。
