The quality speaks for itself- this cover washes well, is easy to install and is undetectable!! My husband suffers from allergy-induced asthma and so it was important to find a mattress cover that offered complete protection from environmental allergens such as dust mites. We have been sleeping on this cover for one week and his breathing is noticeably easier at night. We also have two big dogs who share our bed and I love knowing that our brand-new mattress is completely protected from muddy toes and puppy drools. We had just put it on when our dogs ran in from the rain and jumped on the bed leaving black footprints all over... back into the washer it went and it came out looking just as pristine. The overlay fabric is extremely soft, it fits my king mattress with dual pillow-tops perfectly and this cover makes absolutely no noise. It's a fantastic investment and I am so thankful I found it, thank you Wayfair!!
