Review: Excellent quality encasement - The quality and construction of this mattress encasement is excellent. It is quiet and doesn’t have that plastic sound like some others. The fabric is heavy and tightly woven. Make sure to buy the fit for your mattress depth. Mine fit my 11” mattress perfectly and was easy to put on. The closure is sturdy. It was nice that felt squares were provided to cover any sharp or rough areas they might damage the cover, and that zip ties were provided to lock the zipper closure beneath the velcro flap.
Review: Dog accident? No problem! Phew! - Amazing cover. I bought a few to keep all my mattresses protected, not from anything in particular, but I liked the idea of a keeping my mattresses pristine. I've had these for at least 3 years, and this past week one my dogs had an accident on the bed. Urine soaked through the flat sheet, the fitted sheet, a mattress pad, and I was so bummed to see the encasement also soaked. HOWEVER, when I removed it from the mattress, the mattress was as clean as ever! I was so elated. Certainly an excellent buy for $40 to protect an expensive mattress. I know waterproofness can wear in the wash and depend on the accident itself, so I'll specify that I've washed and dried the encasement as directed just once when I received it, the volume of liquid was pretty significant (likely the full bladder of a 60lb dog), and the accident was discovered within 20 mins or so, so it wasn't sitting for an extended duration (like overnight). The encasement is a pretty good fit and doesn't slip around. Its not something I even notice is on the bed. Its as though it isn't there at all, so its as comfortable as my bed. It is not thick, in terms of being plush, which is perfect. Great buy! Would recommend.
