Hopefully it’s a bit clearer now. Removed the multipack reference. You can buy 1, 2, or 4 pillows.
These are not memory foam, I did a goof and ordered the wrong set 
They are shredded memory foam, right? Oh snap, you’re right. Shredded “fiber”. I have the memory foam version of these.
I thought they would be, but it is a cotton like material. They aren’t horrible, just not what I was expecting
I bought a set of two, but only get to use one, because my five pound chihuahua stole the other. I’m a side sleeper. These aren’t bad pillows. I don’t regret the purchase.
I don’t regret them either, just was under the impression the ones labeled bamboo were all memory foam. I still have been using them as well, and my English setter stole one for her bed too!
