FIELD : medicine.SUBSTANCE : invention relates to medicine and medical technology, in particular, to the construction of a bed for the treatment of patients with tissue damage resulting from thermal, chemical, electrical and radiation effects, and is aimed at equalizing the pressure of the patient' s body on the supporting surface, resulting in a decrease in the likelihood of the formation of pressure sores. Method of providing therapeutic support for a user includes a canvas of a supporting surface, a supporting surface frame, attachment elements for a tension device and a tension device. Shape of the supporting surface for the user is formed depending on the individual physiological curves of the body of the user of the bed by pulling at least one local section of the web of the supporting surface, at the same time, there is a possibility of tensioning various local sections of the web of the supporting surface due to the stretching of the supporting surface at two opposite points of the opposite edges of the supporting surface along the line connecting these points.EFFECT : method for providing therapeutic support for a user and a device for its implementation have been proposed.14 cl, 9 dwg
