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.

Great value, soft but still supportive – perfect for everyday use
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
Really impressed with these pillows for the price. They’re soft but still provide decent support, and work well for both back and side sleeping. No weird smell and very comfortable overall. Definitely a great budget option! 👍
