Abstract: FIELD: medical furniture; production of the medical overlaid seats. 
     SUBSTANCE: the invention is pertaining to the field of medical furniture, in particular, to production of the medical overlaid seats used for prophylactics of distortions of the curvature of the spine at sitting, as the training aids for development of coordination and equilibrium, for development of the various groups of the spinal muscles and the prelum abdominale, rehabilitation treatment, in particular, of the spinal column and can be used at sitting at home, in school, on the working place and at taking the rest, in the rehabilitation wards of hospitals, sanatoria, military hospitals, and also in gymnasiums. The overlaid seat contains a balancing component and a support. At that on the support there is a fixed post with the hinge, using which the support is linked with the balancing component. At that the contour of the mount of the balancing component is formed in plan by conjugation of 3 arcs of the circumferences and 3 straight lines, which are tangential to the arcs. At that two of the straight lines form the lateral edges, and the third straight line forms the front edge. At that the depth of the balancing component makes 1 - 0.75 of its breadth. The point of support of the balancing component on the hinge is arranged on the balancing component symmetry axis spaced from its front edge making from 0.35 up to 0.45 of its breadth. The distance from the support up to the balancing component in the place of location of the hinge makes from 0.07 up to 0.125 of the breadth of the balancing component. The ratio of the dimensions in the support plan with the balancing component makes 0.8-0.9. The hinge with the post is arranged on the support on the axis of symmetry. The spacing interval between the front edges of the support and the balancing component makes from 0.14 up to 0.15 of the spacing intervals from the front edge of the balancing component up to the point of its support. The overlaid seat, according to the second version, differs by the fact, that the support has the front edge having the arc of the circumference with the radius from 0.45 up to 0.5 of the breadth of the balancing component. The rear edge of the support is made straight and the lateral edges of the support are made with the edges bent in the direction of the balancing component and have the height equal to 0.1 up to 0.13 of the breadth of the balancing device. At that the breadth of the support makes from 0.7 up to 0.8 from the breadth of the balancing component, and the hinge with the post is arranged along the symmetry axis of the support apart from the front edge of the support from 0.25 up to 0.30 of the breadth of the balancing component. At that the depth of the support makes from 0.6 up to 0.7 from the breadth of the balancing component. As the result the invention ensures expansion of the field of application of the seat in the domestic activities, in the educational institutions and in the industry as the prophylactic and rehabilitating mean for training some groups of muscles of a person back and prelum abdominale. 
     EFFECT: the invention ensures expansion of the field of application of the seat in the domestic activities, in the educational institutions and in the industry as the prophylactic and rehabilitating mean for training some groups of muscles of a person back and prelum abdominale.
