Soft and cooling
Color: White, Size: King, Color: White, Size: King
This pillow cover is great! Well made. Not too thin. Fits my queen pillow like a glove. Came out of the washing machine still looking brand new, with no zipper issues, which can happen with lower quality covers. Zero complaints.

Soft, Cooling Pillowcase That Smooths Out Chunky Filling
Color: White, Size: King, Color: White, Size: King
I accidentally ordered the king size instead of queen, but it still fits my shredded latex foam pillow fairly well and feels comfortable. The pillow has small but chunky latex shreds, and the added foam layer in this pillowcase not only smooths out those chunks but also adds a bit of extra thick comfort, making the pillow feel more uniform.
It seems to help with temperature regulation—if anything, it’s subtly cooler or at least not any warmer than my previous pillowcase. I’ve washed it twice so far, and it shows no wear and seems well built, so it should hold up over time and seems totally washable. Overall, it’s a very functional item, and compared with similar products, the value seems reasonable; I’m happy with the purchase and just wish I had ordered the right size.

Good quality cover
Color: White, Size: Queen, Color: White, Size: Queen
First, this pillow cover arrived in a plastic bag (see 4th photo), not a box as the photos online show. Although that does not matter to me, it may matter to other people such as those who intend to give this as a gift.
One of the photos I included shows the fabric makeup which is mostly polyester and memory foam with the outer cover having “40% Bamboo Rayon.” It seems like an overstatement to me to market this product as a “quilted bamboo pillow cover” where there’s very little, if any, actual bamboo in it. If you have read up on what “bamboo rayon” actually is, you’ll understand.
The material make up aside, the cover is soft and puffier than a cotton pillowcase. Bamboo rayon does have qualities that allow airflow for a cooling type of effect. It washes very nicely.
As for the size of the pillar cover, I have tried several pillows inside this case, and the case is at least 2 inches longer than every standard pillow I own (See second photo). Pillowcases with a zipper generally are more fitted in every dimension. This pillow cover fits in all dimensions, except for it is longer than necessary. Not a horrible thing, but worth mentioning.
The sewing of this product is good. It has a standard plastic zipper. There’s piping around the entire seam area for touch of class. The gray piping on mine matches the quilting. This is not quilting of the standard sense where threads go through to the other side. It is more of a faux quilting, which you can that on the inside in the photo with the tag.
Overall, it seems to be a good product especially for people who sweat when they sleep.

Very easy and convenient
Color: White, Size: Queen
Absolutely in love with this pillow case. I have a tendency to let the kids on the bed with snacks and it’s helpful to just be able to take the case off and put it in the washer when it’s dirty
