I use this felt pad by Brabantia on my ironing board, it is very thick. I use 2 pads on my current ironing board. Had the pad on my old ironing board then found a big ironing board at an estate sale so bought a pad for that board. Later decided I didn't want my 1st ironing board anymore and took the pad from that one and put it on my big board so that's why I have 2. They are currently $19.
