300 thread count for the cover, and, yes, they ARE machine washable ( with tennis balls. Haha weird). I mention this because NOWHERE in the description or details has this been mentioned. Even in the questions, somebody asked, and got no response, Well, theyre about to get one :) I ordered just 1, to see if my daughter would like it. She just got a new queen mattress, upgraded from a full. That mattress she got is from Heaven..well, almost :) and King pillows just made more sense. My late father ALWAYS bought king pillows. Anyway, I mention that, because standard and queen seem the same to me. Anyway, these are super firm, yet super soft and comfy. She has slept ALL night, and not moved from that position. She usually wakes up after 3 hours. Buy these! Great pillow. She is getting 3 more.
I too have difficulty finding a PERFECT, long lasting Extra Firm pillow. The King size, Ultra Firm by Cannon lasts about a month or so, then I notice that I need to start smashing in the sides for center height. However, at this point, the price is low enough where I can purchase a couple at a time...until I find the "perfect, non lumpy" pillow.
I ordered 2 king size pillows with the same density. The pillows I've bought at the dollar store are better than these pillows. Both pillows were flat when I received them in the mail. One of the pillows was even flatter than the other. I will never order them again.
Claim to be extra firm pillows. Not at all. Was not impressed. Waste of time buying.
