Disclosed is a supportive chair for sitting comfortably at low heights above and relative to the ground. Preferably, the chair comprises a primary seating surface and a secondary seating surface curving around the rear of the primary seating surface to provide additional support for the user. It is preferred that the secondary seating surface be inwardly and downwardly sloped and provide a low lateral boundary for the user, thereby promoting proper alignment of the buttocks on the primary seating surface. Thus, the chair raises the buttocks and hips of the user off of the seating level, creating a relative height difference between the hips and legs. This raising of the hips relative to the legs creates a sitting posture that promotes vertical back alignment. As a result, the user is able to comfortably maintain this position with a reduced amount of back muscle strain, allowing prolonged comfortable seating periods.

L'invention concerne une chaise de support permettant de s'asseoir confortablement à faible hauteur au-dessus du sol. La chaise comprend, de préférence, une surface de siège primaire et une surface de siège secondaire courbée autour de l'arrière de la surface de siège primaire de manière à fournir un support supplémentaire pour l'utilisateur. La surface de siège secondaire est, de préférence, inclinée vers l'intérieur et vers le bas, et constitue une limite latérale inférieure pour l'utilisateur, favorisant ainsi un alignement approprié des fesses sur la surface de siège primaire. La chaise permet ainsi de soulever les fesses et les hanches par rapport au niveau du siège, créant une différence de hauteur relative entre les hanches et les jambes. L'élévation des hanches par rapport aux jambes génère une position assise favorisant l'alignement vertical du dos. L'utilisateur peut ainsi confortablement maintenir cette position permettant un étirement réduit des muscles du dos, ce qui lui permet de rester confortablement assis pendant des périodes prolongées.
