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.

Comfortable, Hypoallergenic, and Great Value
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
These pillows are a solid upgrade for everyday sleep. They’re soft but still provide enough support for both back and stomach sleeping, and the down-alternative fill is perfect if you’re sensitive to allergens. The microfiber cover feels smooth and well-made, and they fluff up nicely after decompressing. Overall, a comfortable and affordable set that gets the job done.

Best for decorating. Not sleeping.
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
These are perfect as inserts for decorative shams and the price was great. I don't think that I would ever want to use them for sleeping. They seem slightly lumpy and don't look they would last for very long with constant use.
