Would buy again
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I bought these pillows with the pillow protectors included. After 15 minutes of fluffing the pillows in the dryer they took their shape and were ready to use.

Nice medium thickness. Fits in shames great. Firm for a medium but will work well
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
Nice pillows for the price. I got the medium thickness and it’s a little stiff, but I think once slept on, it should soften up a bit, but if you like a softer or flatter pillow, definitely go for the soft one. But the quality seems to be very well-made. It puffed up straight out of the package. It didn’t have any smell whatsoever, and it fit perfectly in my standard size shams.

Loved them but may not last too long
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I’m kind of torn on these. I love them and I want to buy more because they were very affordable and very comfy! I’ve had them less than six months and they lose their plumpness after a few nights sleep but they are easy to fluff back up. They are pretty thick and firm but form to your head and neck perfectly..for me at least. I’ve tossed them in the washer and dryer and they have been fine. Fluffed right back up perfectly. The material inside seems to be clumping together now. it’s easy to fluff them back out but you can notice the spaces where they’re starting to clump and even though they can be fluffed again it does seem they are starting to become compacted and I find myself having to fluff them more often. I’ll see how much longer they’ll last, but I will buy again because they are pretty comfortable. I love the covers they came with also. They stay cool and wash easy! Overall, great for the price, maybe not in the long run if you continue to buy, but I’ll see how much longer they’ll stay in good shape!

So comfortable!
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
The best pillow I've ever gotten. I always slept on two pillows and now I only need this one. The height is perfect and it is so comfortable. I highly recommend this pillow for people like me who could never find the right one.
