Updated: actually very good pillows for the price
Size: King (U.S. Standard), Number of Items: 2
Wow! It is amazing at how compact these arrive in their package... it actually was a bit of work to get them out of the packaging it was so tight. Once out, they immediately began to "size up" and within about 15 minutes had reached maximum size. They are comfortable pillows, but lack the firmness that I wanted. On a scale of 1-5, I'd rate them 3 at the most, possible a 2 if 5 is maximum firmness. Updated: After about a month or so of having these, I have to admit my initial impressions were flat out wrong... these are fantastic... comfortable and more firm than I initially thought... probably 4-4.5 out of 5 on the firmness scale now. Maybe they just take a while to decompress? Anyway, would now definitely recommend!

Great pillows
Size: King (U.S. Standard), Number of Items: 4
These pillows are a must buy. Very soft and sturdy. It feels like a cloud when I lay on them. And I love how long they are too. The price for the amount was a huge bonus too.

I only use these pillows now
Size: King (U.S. Standard), Number of Items: 2
We’ll see if they keep their shape so far they have. They cradle my head well and I don’t wake up with neck pain anymore like I used to with my other pillows. Even my JC Penny feather down pillows lost shape so I switched to these and they are perfect. Extra large is great for me as I tend to roll around when I sleep. Perfect for back and side sleepers like me.
