Inexpensive and Nice Quality
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
I was hoping there would be more of a firmness to these pillows, however they are more soft than I was expecting them to be. Id recommend these pillows for someone who wants a fairly non firm pillow.

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
These pillows are quite soft and flat, and offer very little support. I sleep on my side and can't use these pillows. I don't know why they're recommended for side sleepers.
