The invention relates mainly to office chairs, and can be used for the mechanical self-massage the back and paravertebral region. The chair includes a base fixed to a seat and swinging it back with massage elements, the massage elements are arranged on the rear side of the backrest and the backrest is made with the possibility of rotation and fixed in two positions - massaging elements forward and back massage elements. Backrest rest has a support comprising a hinged and spring-loaded relative to each other horizontally, connected to the seat, and vertical, on which a movable backrest portion, wherein said hinge axis is located behind the seat, preferably behind the back bottom. In a preferred embodiment, back rest is mounted on the vertical support portion rotatably by 180 ° around a horizontal axis. In another embodiment, the back rest is mounted on the vertical support portion rotatably by 180 ° around a vertical axis. Rear backrest is formed as a nearly a flat panel provided with dispersed on its area protrusions and / or indentations and massage elements are positioned between the protrusions and / or recesses panel, wherein the panel is adapted to deform under the influence such as the users back, is formed a multilayer, wherein the outer base layer carrying the massage elements are formed thin-walled, preferably from an engineering plastic and the inner layer is composed of an elastic material of low rigidity, for example, made of polyurethane foam.Полезная модель относится преимущественно к офисным креслам, и может быть использована для механического самомассажа спины и околопозвоночной области. Кресло содержит основание с закрепленным на нем сиденьем и качающуюся спинку с массажными элементами, при этом массажные элементы размещены на задней стороне спинки, а спинка выполнена, с возможностью разворота и фиксации в двух положениях - массажными элементами вперед и массажными элементами назад.
