These have a real nice velcro backing behind the zipper and the reduce air flow actually adds to increasing the fluffiness of the old pillows. appears to work really well with allergen reduction and is sturdy, doesn't have any crinkle sound when laying on it.
Ever since I put these pillow protectors on my pillows and a mattress protector around my mattress, we haven't had a problem with bed bugs. It's waterproof, but doesn't feel stiff or like plastic, it's actually pretty soft. Well worth the money.
Having traveled back and forth to NYC (the east coast bed bug capital!), I've purchased mattress and pillow covers for all of our beds; have been doing so for the past two years. Usually pick them up at the local XXXXXX, but saw this set of four and thought it would save me a bit of change. While they were less expensive, they certainly proved the old adage true: you get what you pay for! While the velcro closing all along the top is a great feature, the "fabric" is paper thin. Doubtful it will last any more than a handful of washings before splitting or ripping. This would probably be OK for a guest room that's not used on a regular basis, but other than that I would suggest saving your money. I don't think they make any unnecessary crinkling noise, but am currently covering them with flannel pillow cases that may muffle the sound.
These Bed Bug Blocker 3-layer Pillow Protectors were purchased for avoiding dust mites, my allergy foe. I use the protectors to keep my pillows fresh. No bed bugs to report either, which is fabulous, too. These pillow protectors are super easy to maintain and use. The material is soft, sturdy and quiet, unlike some pillow protectors. This is a good investment for healthy sleeping.
Love the idea of the protection for the mattress but is entirely too difficult to figure our as to how it fits on the bed. Very frustrating and time consuming. Takes two people to figure it and and put it on the bed and I had 3 mattresses to put them in. It rate this a 5 because once it's on the bed it's great.
