Serta Pillows
Style: Side Sleeper, Pattern Name: King

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!
