I got in on the $58 chair at the beginning of the week and it changed my date to 4 business days for delivery as well. I actually did a "save a sale" in store to order the chair because I was there and had the $10 coupon with me (make sure to find a $10 coupon code if you order online to make it even cheaper. you might need to add $2 worth of stuff to make sure you get free shipping still).
Anyway, I got the chair after 2 days, maybe it was just one. It is very high quality from what I can tell so far. The foam will definitely last a while. That's the reason I choose this chair over one of those leather chair deals - mine will actually be around while those will have been discarded after 3 months, or at least being sat in uncomfortably

.
Some of the other chairs look like good deals, too, but this chair is definitely worth the money. Great deal!
