FIELD: personal use daily items, furniture. ^ SUBSTANCE: invention relates to furniture trade and transport, and can be used for development of armchairs of different purpose, pieces of upholstered furniture, and also special types of furniture for medical purpose. Pneumatic regulated lodgment has a base, assembly of springing elements, which are fixed on the base with one end, and form supporting surface of the lodgment and flexible couplings with the opposite ends. Each flexible coupling is made of elastic air proof material in the form of a sealed chamber filled with air, and fixed on the base by the lower end. Each sealed chamber has a port for exhaust air with back-flow valve and port for air supply. All ports of air supply are joined with at least one tap of air supply from atmosphere by pipelines. There are springing elements inside of the flexible couplings. ^ EFFECT: providing comfortable positioning of a user due to that balanced support of the user's body is performed, body shape is reconstituted and the shape of the supporting surface in the contact zone is steadily kept without creating local reverse pressure on the user's body by the supporting surface. ^ 2 cl, 4 dwg |
