Ask HN: What desk and chair should I buy?

I am thinking about buying an Aeron chair this summer and am wondering what kind of desk I should get to go along with it. Is there a desk that has the reputation of an Aeron chair? Also, is the Aeron chair really as good as advertised? I have started cracking my back and neck and I think that a quality chair might fix that problem, is the Aeron the best choice?
