Love these! I ended up ordering more of them!Re: Reason I bought theseWe have a rescue Yorkie that likes to sleep on the pillow. The dog rescue "botched" her spay (from inexperience or trying to rush through the procedure?), so now she leaks urine. She isn't even aware she's leaking, so has no control over it. She will even leak urine in her sleep. She wears a diaper, but if she leaks a large amount of urine, some can leak out. I wanted to find a way to protect our pillows.Re: NoiseI've never had waterproof pillow protectors before because I've heard they are very noisy with crackling/crinkling/rustling noises.When the protectors came, I switched out my "regular" quilted zippered pillow cover with a Waterguard waterproof protector. There was absolutely no difference in noise! Out of curiosity, I have been looking in stores since using these, and can tell that most brands of waterproof protectors would be too noisy for sleeping.Re: "Refreshing" an old pillow.We sleep even better than normal with this protector because it gives the pillows a "cushy" feel to it. Over time, our pillows have gotten a little flatter, so the thickness of the new protector added a little more height and makes it seem like we are sleeping on a new favorite pillow!Re: WaterproofingI poured some water in the middle of a protector and checked back an hour later. I used a paper towel to check the inside and there was absolutely no water that had leaked through.Re: FabricI gave 2 of these to my mom and dad to try. My moms first reaction was same as mine - they are extremely soft on the inside and outside. They are very happy with the protectors too.Re: Additional Uses for the Protectors1. For taking your pillows on trips, to protect from bed bugs, etc.2. To protect your pillow from drooling in your sleep3. To protect your pillow from body oil and odors that go through your pillow case.4. To protect dog bed foam from dirt & wet paws (use between foam and cover if bed has removable cover)5. To give as gifts.One last thing - because we love the pillow protectors so much, we are also using the Waterguard mattress protector too, because of our dog leaking. I was afraid it would make the mattress feel warmer because of the waterproofing, but it doesn't!
