(6" - 8" Depth Mattress, Twin 15cm ULTRA LOW PROFILE) - The Original Sleep Defence System - Waterproof/Bed Bug/Dust Mite Proof - PREMIUM Zippered Mattress Encasement & Hypoallergenic Protector ...

I bought the King size version of the Low Profile Mattress Encasement Cover and I can confirm it fits a 7" thick Mattress perfectly!! It could probably go to as high as 9" without overly stretching it (if you wanted to). But 7" was a perfect fit. It was relatively easy to put on too (even for one person) Two people would be easier but its not hard to put on. (10 minutes at best). The quality is great. The material is not rigid or stiff, but neither is it overly stretchy and clingy. It feels very soft and has a slight silky feel to the touch. By that I mean it feels very well made. The Zipper is smooth to open and close (not scratchy) and it opens up all the way across and then around half of one side of the mattress cover. Perfect for installation (and / or removal) I can't say how waterproof it is as I didn't need it for that (or test it). But it appears to have some decent water resistance. I put a Foam Topper on top of my encasement cover and it works very well that way. (I could have also put the foam topper inside the encasement along with the mattress too) as there was enough room for it to fit inside (but I prefer the way I did it). As I see it, if you need a "low profile" encasement cover I can highly recommend this product. Its quite pricey, but quality is rarely cheap. I'm very happy with this purchase. The Seller got it to me (from the USA to Canada) in record time. It came exactly as described and was well protected inside the shipping box. There are "No" negatives at this point to this purchase (except maybe the price) Again (just to be clear) For anyone needing an encasement cover for a Mattress that's between 5"- 9" thick, this one will fit those sizes perfectly. Its advertised as Low Profile, but that's mainly because its not High Profile. (as in over 10") To put this little review in a Nut Shell, I can honestly say "Look no further" if you're searching for a quality encasement Mattress cover in the 5" - 9" thick dimensions. This is the one. Happy!

Excellent

I am impressed with the design of this item! I was not expecting it to be as nice as it is . The material is so much better than any of the others I've purchased in the past. This is well worth the fue extra dollars it is and the zipper tie holder is very well made and I will definitely order another one for my next mattress I get soon.

Well made. Fit 2 piece king box springs perfectly.

Extremely well made. Feels great under the sheet, not plastic or noisy. Was easy to put on. and i swear....i wake up much less congested so I think it's keeping whatever invisible gross stuff in the mattress, locked in.. Would buy again. and was delivered two days early.
