These pillows are way nicer than hotel pillows!
Size: Queen / Standard, Color: White
This is a real review and I am not a robot. I’m actually sleeping with these pillows right now. They are so comfortable the right softness levels. Oh my gosh they’re awesome. I don’t know about hotel pillows, but these are way better quality form with your head and you sleep like a baby.

Absolutely Amazing!! Truly the perfect pillow!
Size: Queen / Standard, Color: White
I absolutely love these pillows. They couldn't be more perfect! I have spent years buying and throwing out pillow after pillow. I struggle with a lot of neck and upper back pain and I struggled even more trying to find the right pillow on top of spending several hundred dollars on pillows that just got tossed. If you want a great night of sleep and you want to wake up feeling refreshed and not struggling with fatigue and every day neck or back pain you absolutely MUST give these pillows a try!!! They are super easy to wash, made with great quality and have not once bothered my many allergies like most pillows do. I have not noticed any of the chemical odors moat pillows give off, easy to adjust does great with just occasional fluffing. So far has stayed fluffy for me although I did put it in the dryer a time or two as the instructions stated to help with extra fluff and also because I couldn't wait for them to air fluff when they first arrived, an Air B&B we stayed at had these and I ordered them before we even headed back home I loved them so much I had to order my own and was too impatient to wait!

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.
