Carpet pads are usually recommended for Berber carpets. Using a carpet pad can help to ensure that the carpet is protected, lasts longer, and is more comfortable. Different carpet types do better with different pad thicknesses. Since Berber carpet tends to be very thin, you should use a thinner carpet that’s 3/8 inch or less. The cost of carpet padding is about $0.75 to $3.75 per square foot.
