I think you're right, Jaba! I know mine have improved since my first boom swap.
Today the wool rug pad I ordered (for my ironing board) arrived! Yay. I love pressing on it! The only thing is they shorted me 2" in both directions from what I ordered. Couldn't get through on the phone, but I emailed them and asked them to send the right size asap. This one doesn't quite fit my board, tho I will use it until the other one comes.
My ironing board was so "hard"... this is really quite an improvement!
