Hi Quickstrike,
It really wouldn’t make any difference. While Legget & Platt is by far the largest innerspring manufacturer in the industry … like the other innerspring manufacturers they make dozens of different types of innersprings and they wouldn’t be supplying the foam materials in the mattress and the comfort layers on top of the springs are generally the weakest link in a mattress … not the springs.
There is more about the pros and cons of different types of innersprings in this article and in post #10 here.
