IMPROVEMENT TO MATTRESS FOUNDATIONS

摘要

An improvement mattress foundation includes a grid (6) with cross wires (8) having flattened ends (11) wrapped around the border wire (9). The main springs (5) have slanted bars (26) at an angle of 41 to about 50 with respect to the vertical bars (24). Two clips (29) are used for the attachment of each spring (5) to the grid (6) to assure stability of the foundation. A metal slat (3) is provided with a substantially flat top surface (30) and slanted side edges (32) to improve the strength of the slat and prevent injuries to foundation builders.
