Can’t sleep on them.
Nice pillows but they are too fluffy for me. They hurt my neck.

These pillows are way nicer than hotel pillows!

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.
