Very nice but expensive
Size: Queen Size (Pack of 2)
I love these cases, they didn't let out as much air as I had hoped for out the sides so I only zip it up half way so my pillow stays squishy and moldable and not partially filled with air which changes the feel of your pillow. Other then that they are great, they are very soft and quite, there is no noise whatsoever and there is some thickness to it adding a little more softness to your pillow. I ended up buying a second set. I just wish it had a little more airflow through the sides so I didn't have to leave it unzipped, that kind of defeats the purpose. I also think they are a little more expensive then they should be.

Does not change the pillows effectiveness at all.
Size: King Size (Pack of 2)
As of right now, I have not noticed anything with these covers that would significantly alter the way the pillows feel. I'm greatful that they are not noisy as most other covers are. I also appreciate that they have very much the same feel as the covers that come on the pillows. One thing I can say so far with confidence is that even though this is an additional layer to my pillows, the original feeling, specially with the Eden cool+, has been the same in terms of coolness and breathability.

This crescent pillow protector is more than I expected, as far as softness and just the overall quality of it. I wish my PILLOW was as nice as this protector! Definitely recommend.

Great for side sleepers
It always seems hard to find the perfect pillow when you’re a side-sleeper. This one is great. It comes compressed so you will want to allow some time for it to fully fluff back up. The cover is soft and smooth. I love that it isn’t overstuffed. It provides gentle support and a lot of comfort. I was worried it may be too warm since it is polyester, but it is very breathable and I have not had any issues with feeling overly warm on it. It fits a standard size pillow case. It’s not overly stuffed like some other pillows I’ve tried that were specifically for side-sleepers. I think this world be a great pillow for any sleeping position, really. I wasn’t expecting to love a pillow this affordable, but it gets the job done and I get a good night of sleep. I’ll be purchasing some more for our guest room.
