It might be great bit mine was dirty and covered in little specks of some sort. So now I have to get rid of it and vacuum the bed. Yuck
Edited: the specks were falling off in little gobs and were not part of the mattress. One was a green ball, so no, they were not supposed to be there. It looked like it had been rolled on the factory floor. There are some copper looking infused bits but that isn't what I'm talking about.
