Comfortable Support
Size: King, Color: White
These bed pillows provide good comfort and support for sleeping, with a nice balance of softness and structure. They hold their shape fairly well and work for both back and side sleeping positions. The overall feel is comfortable and helps improve sleep quality. Overall, they are reliable everyday pillows that offer good comfort and support.

Very comfortable. On the soft side.
Size: Queen / Standard, Color: White
Soft, but not too soft. I would actually give 4.5 stars. The pillow is a bit too long and bulky, wish it had a bit more support, but overall, great purchase considering the price. Hopefully it doesn't degrade after washing.

Excellent pillows that are worth the cost
Size: Queen / Standard, Color: White
These are wonderful. Completely relieved my back pain the first night I slept on them -– I put one underneath my back as I slept, and a weeklong terrible pain vanished overnight. Felt like sleeping on a cloud. As others have noted, they are neither too soft nor too firm…they’re really just right, and I think would make great guest room pillows since everyone would like them. These were definitely worth the money.

Great , fluffy pillows
Size: Queen / Standard, Color: White
They came compressed into a small roll so I was wondering how they would do. BUT they fluffed up to incredible size and comfy feel. I am impressed so far!

Pillow comfort and quality
Size: Queen / Standard, Color: White
Bought this for my husband. He is very happy with it. It is well constructed. He doesn’t like too firm or too soft. It meets those requirements. Very reasonably priced. I have bought very expensive pillows that aren’t even comfortable!
