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).

Best pillow protector ive ever used!
Size: Body
I was afraid this pillow protector would inflate with air like every other pillow protector I've ever used (from super cheap to super not cheap). Man was I wrong! You can't even tell it's on the pillow and it doesn't take away from the squishy goodness of the pillow. I love these body pillow protectors so much I've ordered 5 so I'm never without! I also use their regular sized pillow protectors and it's the same exceptional quality. Coop home Good's outdid themselves with this one and I couldn't be happier. Body pillows are expensive and this is a good way for me to protect my investment without sacrificing any comfort! LOVE IT! UPDATE: I've been using these for a few months now and they're just as soft now as the day I put them on. But I have finally given in to the fact that they're a tad troublesome getting on and off. When I first got them I washed them often and line dried (these take a long time to dry, you have to flip them inside out over and over to get them fully dried because the inside will hold the water from the washing machine). However over time I've found myself washing them less frequently because it takes all day to get them dry but also because I'm always nervous the zipper will break during put ons and take offs. You are supposed to squish your pillow into and out of the opening which obviously is very possible but there's no way to avoid putting stress on the zipper opening during this process. Another thing about these protectors is that the greyish strip along the sides is NOT water proof. So everytime I do take the protectors off i find new stains along the sides where the pillow had no protection. And I could be wrong but I think the non-water proof gusseted sides are an essential to the extreme comfort of these protectors so I can't be too picky (otherwise I believe these would inflate with air anytime pressure is applied). If I didn't have young children I probably would've never even realized the sides aren't waterproof. I would still take the coop Home Good's pillow protector with non water proof gusseted sides over the average pillow protector ANY DAY.

Looks and feels very durable. Didn't notice and odor when opened or in use. Fits my Coop Home Goods pillow perfectly! Sleep quality is still good with these covers on.

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.
