The invention discloses a spring unit for use in a sprung unit such as a bed, divan bed, mattress, or other upholstered unit, the spring unit comprising a pocket of fabric or other suitable material and having at least two sub-pockets, each of said sub-pockets containing a resilient member. The pocket will preferably be divided across, laterally, or diagonally so as to form said at least two sub-pockets. The spring unit may be formed with two sub-pockets or three or more sub-pockets each containing a resilient member. The sub-pockets may be of equal length or of differing lengths, and the resilient members will preferably be springs which may be of equal lengths or of differing lengths and of equal or differing rates of compression. The pocket will be divided by fabric or other suitable material which is integral with the pocket or by discrete piece(s) of fabric or other suitable material secured to said pocket to form said sub-pockets. |
