I absolutely love these pillows, I love the fact that they come with a cover to protect them. They're just the right amount of density to them to make them extremely comfortable. They don't flatten down and just stay flat. I've had one set of them for quite a while now and they're still just as good as the brand new ones that I bought. Eventually I will be replacing every pillow in my house with these pillows. They're very well made, The filling is just right, the size is perfect, the quality is absolutely amazing. If you buy these pillows you won't regret it, they're literally the probably the best pillows I've ever bought. And also one of the cheaper ones that I bought in price not quality. And I've never bought any of the store that come with the protective covers with them either. I do highly recommend them.

This pillow is great. It supports my head and is just the right softness. Love the fact that it is machine washable. Would definitely purchase it again.

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.
