WebMar 4, 2024 · Density & ILD ILD stands for Indentation Load Deflection. Generally speaking, softer mattresses have lower ILD’s and firmer mattresses have higher ILD’s. We don’t focus on ILD numbers since we feel they aren’t always reliable. Instead, we classify layers of latex by Soft, Medium, and Firm. WebOct 1, 2024 · The ILD is the amount of weight needed to compress that section of foam by 25%; ILD is expressed in numerals corresponding to the weight. The foams used in mattress comfort layers usually fall between 10 and 20; transitional layer and support core foams usually have much higher ILD measurements. WebILD stands for Indentation Load Deflection, and by knowing the ILD you can tell how firm the foam is. The ILD tells you how many pounds per cubic foot it takes to compress a 4" sample by 25% of its overall thickness. The lower the ILD the softer the foam, the higher the ILD, or the last two numbers of the grade's part number, the firmer the foam. brickies sand price
