upholstery foam 44 ild

If your seat cushions sag the moment someone sits down, upholstery foam 44 ILD may be the fix. This firm foam holds its shape under steady use, so it is a popular choice for dining chairs, benches, window seats, and any cushion that needs to feel supportive rather than plush.

What 44 ILD Means

ILD stands for indentation load deflection, a common foam firmness rating. It measures how much force it takes to compress a piece of foam by a set percentage. Higher numbers feel firmer, and a 44 rating sits in the firm range, offering solid support without feeling like a board.

Firmness vs. Density

Firmness and density are not the same thing. Density relates to how much material is in the foam and often affects durability, while ILD describes how firm it feels. When choosing replacement cushion foam, consider both.

Where Firm Upholstery Foam Works Best
