I don't know if this is comparing apples to oranges or even if its possible, but what would an ILD be for a typical spring mattress?

Not sure what your mean.

ILD refers to how much a piece of foam condenses under weight, in other words how firm it is. That's a simplification but that's the gist of it.

A "typical" spring mattress can be any firmness, but  more often than not they're too soft. The problem with conventional spring mattresses is usually more a problem of the cheap quality foams the use, than it is of the springs. That's why mattress surgery is often a good solution - just cut it open, take out the crappy foam and replace it with quality foam.

As to ILD, a medium ILD for latex is around 28-32.

Yeah it was sort of a dumb question, I was more trying to figure out if there are similarities between what a firm latex and a firm spring mattress would feel like.  Would they feel roughly the same for firmness or would the latex feel a touch firmer or softer.

I think it is hard to estimate.  Also, it will vary widely depending on the coil system, number of coils, and the gauge of the coils.

My perception is that the upper end Sealy springs are firmer than XF (36 ILD) talalay latex from Flobeds.  I did not try their super firm, but I would say that the Sealy coils by themselves are probably closer to that.  So, over 40 on an ILD scale for talalay.

Thanks....I figured there are so many variables it would be hard to tell, but I thought if a few people chimed in with their observations then I might be able to get a better idea.

 

Thanks,
