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.

my fav now after using 50+ pillows
Style: Back Sleeper, Pattern Name: King
I have always struggled to find the perfect pillow, and so far I have had 50+ pillows. Personally, I like my pillow to be on thinner side as I look for more support for my neck.
This is my first time buying pillows online, because I like to physically touch and feel the firmness and thickness before I purchase my pillows. I am so glad I did it! These pillows are just PERFECT for me! Perfect firmness, perfect thickness and perfect material.
One thing I suggest is that be extra cautious when you open the package. These pillows were rolled and put in a relatively thin shipping bag, so when you open with sharp objects be careful not to cut your new favorite pillows!
I let the pillows sit for about 48 hours before I started using them, but I assume you don't have to wait that long.
Overall, I am very happy with my first online pillow purchase with Serta!
