FIELD: domestic articles.
SUBSTANCE: invention relates to a spring mattress containing springs enclosed in cases, i.e., a so called “pocket type mattress”. The mattress contains a set of twisted springs connected to each other, enclosed in cases, parts of a case, located at ends of at least one of springs, are connected to each other through a spring by means of articulation. Articulated parts of the case contain opening (9) through the spring. Cases are limited with at least one longitudinal connecting line and a set of transverse connecting lines passing perpendicular to the specified longitudinal connecting line. Longitudinal and transverse connecting line are connected on the side of springs and essentially in the same plane perpendicular to longitudinal axes of springs. Parts of the case are connected by welding points (10) distributed around opening (9) or continuous welding around the opening. Opening (9) is punched and located within a perimeter of the articulation between parts of the case.
EFFECT: creation of a simple durable thin and non-rigid spring mattress is provided with the possibility of individual elastic deformation, a structure of which eliminates rotation of springs in a case.
