I was pleasantly surprised to find that this pillowcase cover really makes a difference. I placed over a high quality, but well worn pillow that had lost some of its shape and wasn’t helping obtain a good quality sleep. After enclosing that pillow in the very plush fabric of the pillow case protector,  I found that pillow now yields a good sleep. Some of that may be due to the temperature adjusting properties of the pillowcase protector. I tend to get hot, including my head and hair while sleeping. Since I’ve added this pillowcase protector, I have not experienced that, even though it’s been warm. The box packaging looked worn and the sewing did not appear perfectly straight on all four sides, but I’m willing to overlook those minor details because of how it performed. I love that it helps reduce household allergens and offers anti-microbial protection.
