Sleep & Beyond54 by 76-Inch Organic Merino Wool Mattress To

I understand the mattress topper has not been treated with fire retardants, but has the cotton cover been treated with any chemicals..?

Do your wool suppliers certify that they do not practice Mulesing (when sheep, without any painkillers, have huge chunks of skin carved off)?

How come the label says filled with Virgin Wool? Is that the same as Merino wool?

Since this cover is not cross baffled, does the wool buch or shift after some time? Thanks
