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.

A pillow made of extras soft lumps and clumps. Defective.

Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile

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.
