So basically ILD and IFD are the aneroid and mercury "firmness barometers". Two different testing methods to arrive at a common answer: the firmness of any given foam. A low IFD, such as 10, doesn’t offer much resistance and is considered soft. Generally speaking, an IFD of 15-24 is considered soft, 25-32 is medium, 33-40 is firm and 41+ is considered extra firm. The comfort range for the majority of people is 25-32. This message was modified Feb 5, 2010 by Pete

And I'm betting that would be too soft for you. I have issues with low back and hip pain, and what I ended up with is a 100% latex mattress, nine inches of 36 ILD latex (extra firm) with a 2 inch convoluted latex topper of some softer ILD - maybe 24-28? This firmness level allows a very supportive surface, which you back needs, with enough give to provide pressure relief in the hip and shoulder areas. Sometimes I want a softer feel and move over to my husband's side of the bed, and he has 3 inches of firm latex (34 ILD) over six inches of extra firm latex (36 ILD) with the 2 inch convoluted topper over everything. This is a bit too soft for my back, but every once in awhile I like the softer feel. |
