Claims10
A method of manufacturing a bedding or seating cushion core, which:
- cushion core is characterized by slow and gentle compression when a load is placed on the top of the cushion core, said method comprising:
- forming a continuous string of individually pocketed springs, each spring of which is contained within a sealed pocket of fabric, which fabric is semi-impermeable to air flow through said fabric;
- assembling and securing said string of springs into a matrix of pocketed springs so as to create a cushion core having spaced top and bottom surfaces;
- said resulting cushion core being characterized, when a load is placed upon the top surface of the cushion core, by the rate of deflection of the cushion core being retarded by the rate at which air escapes through said semi-impermeable fabric within which the pocketed springs are contained.
A method of manufacturing a bedding or seating cushion core, which cushion core is characterized by slow and gentle compression when a load is placed on the top of the cushion core, said method comprising:
- forming a continuous string of individually pocketed springs, each spring of which is contained within a sealed pocket of fabric, which fabric is semi-impermeable to air flow through said fabric;
- cutting said continuous string of pocketed springs into individual strings of pocketed springs of discrete and predetermined length;
- assembling and securing said strings of springs into a side-by-side matrix of pocketed springs so as to create a cushion core having spaced top and bottom surfaces;
- said resulting cushion core being characterized, when a load is placed upon the top surface of the cushion core, by the rate of deflection of the cushion core being retarded and controlled by the rate at which air escapes through said semi-impermeable fabric within which the pocketed springs are contained.
A bedding or seating cushion core, comprising:
- a matrix of interconnected pocketed springs, each spring of which is contained within a sealed pocket of fabric, which fabric is semi-impermeable to air flow through said fabric;
- said matrix creating a cushion core having spaced top and bottom surfaces;
- said cushion core being characterized, when a load is placed upon the top surface of the cushion core, by the rate of deflection of the cushion core being retarded by the rate at which air escapes through said semi-impermeable fabric within which the pocketed springs are contained.

- assembling and securing said string of springs into a matrix of pocketed springs so as to create a cushion core having spaced top and bottom surfaces;
- said resulting cushion core being characterized, when a load is placed upon the top surface of the cushion core and then removed, by the rate of return of the cushion core to its original height being retarded by the rate at which air escapes through said semi-impermeable fabric within which the pocketed springs are contained.
