The support structure of innerspring mattresses is constructed using wire coils which can be made for firmer or softer support depending on their gauge. Because the coils are placed evenly throughout the mattress, an innerspring mattress has a strong border that prevents the “roll out” effect. A border wire attached to the perimeter coils helps to retain the shape of the mattress and reduce sagging.
As of 12/30/2015, California state law requires retailers to collect an $11 recycling fee on each mattress and each box spring sold. (I.E. A recycling fee of $22 must be assessed for the purchase of one mattress with one box spring.) The amount of the fee was mandated by the state and is not set by individual retailers.
