I haven't seen a thread about this yet, but you can't sit in the Natatorium Chairs from the New Money theme. I just became aware of the problem today when a Yo buddy pointed it out and when I checked mine, she was right, you can't sit in them. He and another buddy of his already sent in tickets, but I'm mentioning it here to see if it gets a Viking's attention.

I can sit in mine. I have the bright ones.

I have the Gray ones and cannot sit in the chairs. I can sit on the Bench but not the chairs (I just checked again).
