Review: RECOMENDABLE - Súper buen producto. Quedó perfecto para el colchón y los materiales son de alta calidad. Recomendado
Review: Excelente producto - La verdad esperaba que fuera un producto medianamente bueno pero mi sorpresa fué otra, es un producto bastante bueno, compré uno de una media de anchura menor y se estiró hasta encajar bastante bien, su cierre es muy bueno y sus materiales también, lo único que no me gustó fué que dejó aire encerrado dentro y se hace una burbuja de aire al acostarse pero es un detalle menor y solucionable. Muy bien producto.

### ⭐⭐⭐⭐⭐ The best at this price..... and possibly the only option at this price depending on what size you're looking for....
*by A***J on 6 May 2016*

I don't have bedbugs but I work at an institution that does (and that might as well laugh in the faces of any staff that gets them) I work with with disabled residents whom I have a good enough rapport with that I get a lot of not quite consensual hugs. Sweet, kind of, but unreassuring when they refuse to put their potentially bedbug infested clothing and linens on high in the dryer my employer provides them. I also have the most rascally service dog (my first ally bully breed mutt) who can be found at my workplace midday snoring loudly while napping on her back on the bedbug infested carpets. She waits until she thinks I am not looking and then she will try to cuddle up on the bedbug infested couches with whichever client smells like s/he has the worst hygiene Also, the ever non-discriminator she likes to try to cuddle with the sleeping homeless of San Francisco when we're out on walks. I give her a lot of baths but I'm still never sure. I wanted some piece of mind without having to dodge ever hug from my clients and have to keep my dog on leash at every park in city limits. My dog also has a bad habit of sneaking onto my bed and spite peeing in my bed after every time I kick her out for sneaking in. (She's allowed to be on the bed but only if I'm in it.) My current 15 year old mattress has an almost $50 Allerease Ultimate cover on it that was put on there one dog ago. That cover works well despite a small tear it got when I was putting it on that I had to tape up (the Allerease cover tore easily over a regular Full matress). The Allerease sleeps very cool, is highly liquid resistant, helped my allergies, was virtually undetectable below the sheets, and hadn't gotten any bedbugs despite the neatly taped up hole. WIN! Hence, when I tried to buy new covers for my brand new folding Full size foam futon base and my brand new Full size custom made Japanese shikibuton matress I was going to go with Allerease Ultimate again. However, those covers were much too big! There were limited options for low profile covers that protect against both bedbugs and rascal dogs and this was one of the few. I bought the Low Profile Full for my folding foam base matress. It didn't fit perfect and it did make it moderatetly more difficult to fold/unfold but it went on easy enough and was sturdy enough not to tear when I put it on by myself (unlike the Allerease). I put a high thread Queen size duvet cover on top it (queen size to account for folding and the fact it's thicker than a duvet) and slept on top of that for the first week or so until my custom-stuffed Full size shikibuton matress came in.. It sleeps warmer than the Allerease despite being a thin foam matress on cement on the ground level of my loft. My last matress that had the Allerease Ultimate on it was a thick pillow top extra firm matress on a wood base in a loft that is ten feet up from my current sleeping spot. It hasn't been a big deal but it's significant enough to notice. It appears to be water resistant and likely waterproof. I don't know about bedbugs but I think it would probably deter them and I'm neither daft nor dumb nor daring enough to test that one. But it doesn't have a duct taped hole in it from putting it on by myself so it would probably work okay. This one is definately more sturdy than the Allerease Ultimate but it's more noticable to me. Thankfully, it's not a crinkly plastic so it's not too noticable. I notice but my bestie (who loafs on my matress watching TV) and my dates don't notice. The rascal dog who is easily the most pathetic service dog I've ever trained is scared lying on plastic tarping and so she either doesn't notice or her desire for sleeping in the big bed trumps it. I will admit I still like the Allerease Ultimate slightly better.... but the price is way better on this one, too. It also comes in low profile which I needed. I ordered it again, this time in Ultra Low Profile for my new shikibuton matress that just came in. Shikibutons are not thick like their American mattress cousins and despite my custom cotton/wool blend extra thick custom shikibuton order, my new matress is far more trim than it's cousins from out West. Indeed, a Sleep Defense System cover was pretty much my only option without dismal reviews off a very short list. I liked the last product well enough I was like, "Oh, what the heck." It's a four star product. However, with the price and shipping service I got when I ordered it from Hospitology I've decided it's close enough to five stars to round up.
