Spring structure for a mattress innerspring having coaxial coil units

An innerspring structure for a mattress comprising:

• a row of outer coils, the row being formed from a continuous piece of wire with the adjacent coils of the row interconnected with interconnection segments;
• a row of inner coils, the row being formed from a continuous piece of wire with the adjacent coils of the row interconnected with interconnection segments;
• said interconnection segments of said rows of coils forming adjacent coil heads for pairs of adjacent coils and each coil head including a first linear portion disposed generally parallel to the row of coils;
• the row of inner coils being positioned together and generally coaxially with the row of outer coils for forming a row of reinforced coil units;
• a helical lacing structure extending along the row of reinforced coil units and winding around portions of the inner and outer coils of the row to couple the coils together into the reinforced coil units, the first linear portions of the coaxial coils in the row forming the reinforced coil units configured for being captured by the helical lacing structure for further forming the row of reinforced coil units.

A spring structure for use within an innerspring structure, the spring structure comprising:

• at least one pair of adjacent coils formed from a continuous piece of wire;
• an interconnection segment connecting the pair of coils at an end of the coils;
• said interconnection segment forming adjacent coil heads for the pair of adjacent coils and each coil head including a first linear portion, the first linear portions of adjacent coil heads disposed generally parallel each other;
• the first linear portions configured for being captured by securing structures so that the pair of coils may be secured within an innerspring structure;
• said interconnection segment forming a spanning portion extending between the pair of first linear portions to couple the first linear portions together, the spanning portion extending generally perpendicularly to said first linear portions.
