Inexpensive and Nice Quality
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
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.

Soft and Comfortable Pillow
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
This pillow has a soft feel with a nice balance of comfort and support. It fluffs up well after opening and maintains its shape throughout the night. The cover feels smooth, and the overall construction appears well made. A comfortable option for side and back sleepers looking for a plush sleeping experience.

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
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.
