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!

Pretty good.
Size: Queen / Standard, Color: White
Me and my fiancé have been going through a lot of pillows, trying to find the right ones. We go to this local hotel to unwind and use the whirlpool sometimes. Their pillows are immaculate. So I starting looking at “Hotel Pillows”. These are not the same as the hotel pillows, not even close tbh, but they are the best ones I’ve bought so far. They are comfy from day one. I was worried when opening the box and seeing that they had the same cover on them as others I bought before, but they were not the same. Pretty comfortable, and less neck pain than any of the other ones. My house is like the house of pillows and I am finally going to start getting rid of the old ones. Maybe we’ll find some down pillows to put on our registry, but until then, these are staying on my bed.
