Yes I did, from Northern Tool.
I sent it back, NO cushion in the tail bone area at all. I actually called the company and asked them if maybe it was a seat that maybe during the manufacturing process that it maybe by chance the foam was left out of that area.
The guy said he would check the others to see if they were any different than I was describing and get back to me. He called back a day later and reported they were all the same. So I sent it back.
I do have a bony butt, so if you've got a lot of cushion there you maybe fine, that's your call
