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.

A pillow made of extras soft lumps and clumps. Defective.
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
This pillow should not even be sold. It's simple a super soft pillow with lumps of clumps of softness. Part of my head was even touching the mattress through the clumps. I ended up throwing it on the floor at 2 am and my head and neck hurt from it. I have never had a pillow of lumps before. I hope I can return this thing.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
