Great pillow
Style: Side Sleeper, Pattern Name: King
Love them, very fluffy and full not flat like my old pillows. And they are easy to fluff even if they go flat after sleeping on them

Great Pillows
Style: Side Sleeper, Pattern Name: King
I was very skeptical about purchasing pillows online. After much research, I decided to buy two of the king size pillows. When they arrive, they were rolled up tightly in plastic. I fluffed them up and got new pillow cases for them. The first few days, I was tossing and turning. After giving them a few days, I can honestly say they are very nice pillows. Not to firm and not to soft...a very nice medium! They have a cool feeling when you lay on them. These pillows are great for those who sleep on their back AND side sleepers. No feathers have been poking out. My significant other LOVES these pillows. Been sleeping great and feel like I made a great decision getting these. Great value, great materials and great quality. I highly suggest trying these out if you're looking to replace your pillows.

Great quality but big
Style: Side Sleeper, Pattern Name: King
These pillows seem to be very good quality. I couldn’t wait to try them. I soon realized that they’re very thick & too high for my neck. I can push the pillow down but it doesn’t stay so I’d say they’re too firm for me & don’t support the neck properly because of the height.
