Nicest Bed Pillow Protectors I have found!
Size: Body
I have ordered these pillow protector cases multiple times for pillows that are extra thick or lofted as these seem to be very comfortable, durable, and really protect the pillow itself! They wash up well if there is any sort of stain. Nice bed pillows can be a real investment…it’s both easier to wash these protectors with my bed linens and more sanitary overall. Thin pillow protectors either wrinkle or fail to actually protect the pillow itself from whatever…dust mites, head lice, sweat, make up, skin care, spit up….be sure to follow the instructions for laundering and drying them and they will last a long time! My experience is these protectors keep my pillows from getting lumpy or bunching up, so promote a better night’s sleep!

This is definitely not your average pillow protector!
You have to see and feel this pillow protector to understand just how good it is (photos and videos just don't do it justice). It looks and feels like some sort of fancy premium luxury pillow case, but it's a zippered pillow protector! I always thought pillow protectors were just a simple white cotton zippered pillow case in order to add another layer in addition to the pillow case, but this pillow protector from COOP Home Goods completely blows me away. I just kept going, "Omg, are you kidding me? This is just a pillow protector?! Wow!" The only negative is, the zippered opening is too small. When I tried to put my brand new COOP pillow into it (I have the pillow that has approximately 15,000 reviews), it was very difficult. This was before I removed any of the filling for customization though, which I still needed to do. I finally got around to doing that and I probably removed about 1/3rd of the filling because I'm mostly a stomach sleeper, so I'm sure the pillow protector will be much easier to put on the next time I remove it, but I'm not going to remove it until I have to wash it because I don't want to be stuck trying to put it back on again! That's how annoying it was to put on. I'm keeping it though because I'm hoping it will mean I'll never have to wash the pillowcase or especially the pillow! That'd be awesome. I recently upgraded from a MyPillow Premium and I hated washing it (it was always a mini project, so I am hoping to be completely done with that). I contacted COOP about the small opening and they said, "We do have plans to change the zipper placement on our pillow protectors, however, production has not started and we do not have a firm date to provide you with at this time." They also reminded me that the pillow can be "bent and manipulated" (their words) into the pillow protector. See next paragraph though to understand why I didn't want to handle the pillow too much, otherwise I would've just done that instinctively. There is one more negative aspect that's worth mentioning, but it's due to a personal issue (there's nothing COOP can do about it). I have rough dry skin on my hands, and the material (40% Bamboo-derived Viscose Rayon, 60% Polyester) is rather 'catchy' on my hands. If you have rough dry skin and if you've ever tried to handle something made out of silk, you know what I'm talking about; you can't enjoy the silky smooth texture. This isn't anywhere near as bad as silk, but it's just bad enough that it's worth mentioning. I think it's due to the Bamboo-derived Viscose Rayon. The pillows are the same way for me due to the pillow case. That's probably what made the pillow case so difficult to put on because I was trying to be very careful not to get my skin flakes all over everything from just "manhandling" it, which is what I should've done and then just vacuumed it clean. heh I won't use lotion though because I don't like the idea of getting lotion on everything I touch every day, and it makes my hands sweat much easier - especially in the summer. So, I prefer to just deal with clean but rough dry hands. I guess another negative thing could be that it's not possible to just buy 1 pillow protector. These are 2-packs. I only needed 1 pillow protector and I only wanted 1. I would've gladly paid $15 for just 1. So anyway, beyond that, these pillow protectors truly have that "wow!" factor. They're exactly as advertised and more (because some things are only possible to know about by experiencing them for yourself).
