Abstract

The spiral spring mattress comprises a number of interconnected spiral springs enclosed in casings, ie. a so-called pocket mattress. The springs (1) and casings (2) are so dimensioned that the spring natural height (NL) when they are not enclosed in the casings exceeds their maximum height (ML) when they are enclosed by at least 50 per cent for at least one spring.
