Immediate neck and back pain
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
Nice full pillows that holds its shape, BUT was NOT good head and neck support. I noticed an immediate difference. From non existent to growing neck pain in the first night’s use, through the week.

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.
