Each spring coil has a length of spring wire formed at opposite upper and lower ends in respective upper and lower end turns and in an intervening coil extent therebetween. The spring coils are characterized in that the lower end turns of each coil is closed by a knot formed between the lower wire end and the coil extent. The spring coils are further characterized in that the upper end turn of a first selected number of the spring coils is open with the upper wire end unknotted to the coil extent and the upper end turn of a second selected number of the spring coils is closed by a knot formed between the upper wire end and the coil extent.
