Cooling and comfortable pillow cover
Color: White, Size: Queen
This is a very nice pillow cover. It’s very well made, has a zipper and the fabric is what I consider as plush. It’s very pretty but I use it under the pillow case. The best feature to me is that it keeps my head cool. I sleep on a latex pillow and they are usually too warm for me.

Pillow case
Color: White, Size: Body
Here is another example of a review about a pillow case that matches your description:
I ordered this pillowcase because I needed a pillow case on my special body pillow-that was long, cozy, and soft. I was not disappointed. These pillow case are made from 100% organic bamboo viscose, which is hypoallergenic, breathable, and silky smooth. They have a special shape that fits my extra-long pillow perfectly, and it doesn’t slip off or bunch up. This is also very easy to care for, as it is machine washable and wrinkle resistant. I like chose the white one because it looks elegant and fresh. This pillowcase definitely worth the price, and I would recommend it to anyone who wants a high-quality pillow case that is long, cozy, and soft.

Wonderful pillow and products!
Color: White, Size: Body
I've been using the Snuggle-Pedic pillow for a couple of weeks now, and it is fantastic. It's soft, but the foam is firm and full. It is clearly extremely well made. Everything from Snuggle-Pedic appears to be top quality, right down to the extra little instructional inserts they include with their products. I also purchased the Zipper Removable Cover to make laundering easier. It's just as well made as the pillow. In fact, it's exactly the same as the cover on the pillow except removable due to the zipper. I'm also using the Snuggle-Pedic Organic Cotton Pillow Case, and it too is extremely well made, soft and comfortable.
I was a little hesitant about the pillow case when I saw the picture because it almost looked ... too soft for me, sort of like a fleece blanket. Maybe that was just the way I saw the picture, but it's not actually like fleece. It's very soft and comfortable and does stretch a little as opposed to a regular pillow case, as they say in the description, but in a good way and appears very durable. I was concerned that it would stretch out and twist around the pillow, but it doesn't do that at all. It has stayed perfectly fitted to the pillow. From what I've experienced, everything in the descriptions of the Snuggle-Pedic products is true, and all three pieces work perfectly for me. This is the most I've spent on an individual pillow, but I couldn't be more pleased, and I'm planning to replace all my pillows.

Cool Slumberings
Color: White, Size: Queen
For transparency, I was given this pillowcase to review by Relief Mart. However all views are my own and not biased because of it.
I had recently purchased the matching pillow (see my other review) and had the opportunity to try this out. In terms of specs, it's basically made out of the same material as the Snuggle-Pedic Bamboo Shredded Memory Foam Pillow - it even has the same woven design. According to manufacturer claims:
'Soft and Luxurious Kool-Flow® Micro-Vented Bamboo Cover' - The pillowcase material is very soft to the touch, and does have a premium feel to it. It did have a slight 'smell' when it first arrived, however once washed (and air dried) it's not there anymore.
'Unprecedented breathability that allows air to circulate through the pillow' - It definitely keeps a certain 'coolness' and doesn't heat up if you stay in one spot. It makes staying still bearable, as I'm a sleeper always looking for the cooler side of the pillow during the night.
As described, it's zippable so you can separately wash it from the pillow, and I can attest that it does keep it's softness and fluffliness after 3 weeks of use. Though I'm very happy with it, there's a couple things to build on in my opinion:
- color and texture of fabric. By itself, the look of the pillow makes it seem that there's no pillowcase. So if you're picky about your bedsheets when you make your bed, this pillowcase will probably stick out like a sore thumb. The unsubtle branding and slight off white coloring doesn't help as well.
- there's a tag outside the pillowcase near the zipper, and though it doesn't affect it in any way, it can be slightly annoying and aesthetically displeasing as it sticks out a bit. Would suggest placing it on the inside.
I would definitely recommend this product, irrespective of the (minor) points above, as this has made my slumbering experience a whole lot better.

Great pillow case from a company that cares!
Color: White, Size: Body
The Snuggle-Pedic Body Pillow Case is GREAT and is the perfect pillow case for their body pillow! Feels exactly like the great material that's on the body pillow (soft and breathable) -- and it fits the pillow perfectly! I love that there's a zipper on it as I don't have to deal with the pillow slipping out of the case at all. The case fits perfectly and is the perfect case for the pillow! I read some other reviews where people said they didn't love that the tag/label was on the opposite side of the zipper on the case. But for me this was a non-issue. I cut the tag off and now there's no issue at all. :)
Oh, and I have to give a shout out to Snuggle-Pedic and their company....they are awesome! They did offer me a free case in exchange for an honest review. But this isn't what I think they are awesome for. I find them to be a stand up company that is truly there to support their customers! They include a little note when you get the pillow and pillow case giving you their phone number and letting them know they are here to help if we have any questions. And they send an email as well saying they are available if we have any questions and they gave suggestions on how to care for their products. They are quick to respond and truly lovely people. I'm a sucker for supporting good companies....companies that actually truly care about their customers...and this company is that! I highly recommend this product :)
