Question: It says 11" high.  Our Temperpedic bed is 12".  Would it stretch to fit?
Document: Install was easy. Fit is was a little loose on my 9&#34; deep mattress. Otherwise, I would have given 5 stars. It looks like a clean, decorative cover. I would recommend this to a friend. You don't need to hire an expensive exterminator. Just be logical and take away the bugs' hiding places. Mattresses are so insecure. Bed Bugs love them. Use these covers to keep them from go in and out of the mattress.
I also think this is a fair price for protecting a mattress which is a high price ticket item . Hopefully if there are any accidents this product will protect my mattress. I would reccomend this item.
This is a wonderfully  made product. Mine fit nicely for a double bed. The zipper was strong and was easy to put on.Have no complaints .Thank you
We have a home made stunning solid oak twin swing bed and this has completely protected it!PLUS, we bought the more thick memory foam mattress and it still had extra room !! Will fit any size twin mattress that I know of! !
I would never have a bed with out a mattress protector. It has really saved me , spilling drinks in the bed. Just change the sheets no harm done.
I've had these protectors for a month now. Along with the bed protectors, I purchased the pillowcase protectors too. To have bed bugs is a humbling experience that will change your life... Yes, a bug no bigger than an apple seed will do this. These protectors made me feel as if I were getting part of my life back. They not only fit my king size bed perfectly, they feel really good! My bed now feels plush.
I order this to protect a queen-sized mattress and memory foam pad from dog fir (and smell) from our rather large dog (116 lbs and growing) who sleeps on this bed. Although a bit challenging for one person to get onto the mattress and pad, once I had it on, it fit great, zipped easily and know I don't need to worry about the dog ruining the mattress or topper.
My husband refuses vinyl, even the expensive quiet type, and I want a waterproof mattress protector (bed bugs aren't a problem but I don't object to the extra benefit). We have a fairly new pillowtop, about 13&#34; deep so not super-thick. This cover fits it perfectly - loosely enough to go on easily without pulling anywhere but it doesn't slide around or bunch on the sides like our old one, that fit up to an 18&#34; mattresses, did.
I don't feel like I'm sleeping on a garbage bag. I recommend these protectors even if you don't have bedbugs. I wish I knew about these before this, I would have purchased  pillowcases and bed protectors for all the new beds. I've done a lot of research on bedbugs and bed protectors and it's been recommended to purchase higher end protectors as oppose to the cheaper ones. Guardmax Bedbug Proof Mattress Protectors do the job at an affordable price.
I purchased a brand new bunk bed for my 6 year old. I fell in love with the soft memory foam mattress they had at the store which bumped up my purchase to a whopping 3x that I had initially wanted to pay. It wasn't until the mattresses made it home did I ask myself what in the world did I do getting my 6 year old expensive mattresses he was sure to mess up? ?I jumped online quickly looking for waterproof covers that zipped and would withstand an energetic, bouncy kid.
Answer: Yes. Because mine is 10 inch double and still have a little wiggle room.It's nice too. Was surprised how nice it was.  TIP:  stand mattress on long end and start at the top and work your way down...just makes it easier.
