A must for rentals
If you have lodgers or visitors with children and want to keep a clean house this is a very strong and very inexpensive way of showing it off. It installs in seconds (we put the mattras on the floor so it slides easiest) and a zip around keeps the mattras safe from liquids but also from bed bugs.

Sounds loud and crunchy. Cheaply made.
This is more like the kind of protection you add to a small child or baby's crib. It sounds terrible. It did fit but it's not going to last. I do not know for sure if it's waterproof. It's ok for a temporary king sized mattress protector but I would recommend you buy another type for loner term use. I am completely disappointed.

Great fit

The Mainstays NexGen Zippered Mattress Protector is a life saver. This product is fantastic. It helps prevent dust from getting on your mattress. It's also good if you have a small child who sometimes sleeps in your bed and me wet the bed on occasion. This will completely protect your mattress from any spills or any little accidents. It is easy to put on your mattress. I would highly recommend everyone.

An investment must

We love our Mainstays mattress protector. I have a large sweaty husband and three dogs that sleep and hang out on my bed. And protecting my thousand dollar mattress is a must. I figure if I am going to spend that much on a mattress it only makes sense to protect my investment. We spend a lot of time in our bed, so we snack and drink, and the dogs are very messy. And this wonderful mattress protector saves me a great deal of stress and you do not even know it is there. Because it is so quiet and soft, I have had other that were like a plastic sheet, and thats not comfortable. I think everyone should use these, and at this price point, who can't afford too.

does it's job

this mattress protector does it's job well. It is water and sweat proof so my mattress won't get sweaty after hot summer nights. It is made out of polyethylene and feels like a light plastic cover. when you put your sheet on, it does make a slight plastic sound, but not loud, and you cannot feel any difference with your sheets. this is a queen size up to 12 inches deep, so it fits my 11 inch mattress just right. it has a zipper closure and is easy to put on. it is also easy to clean, you just wipe it with a damp cloth. I am very happy that it also protects against allergens and that it has a three year warranty.

lightweight and works well

I have a 7 year old who tends to spill water on my bed when we are watching tv together so I am prepared with this Mainstays NexGen Zipper Mattress Encasement. I like that it is lightweight and easy to slide into my mattress. The NexGen is a fabric alternative to vinyl mattress protectors which is stronger. I place my quilted mattress cover and fitted sheet over this mattress protector so it is comfortable when I lay down. Recommended care is to wipe clean with a damp cloth.

Keeps the mattress clean

I used the mainstay mattress encasement on my new mattress and it gets the job done. I have kids that aren't fully potty trained yet and insists on sleeping with me every night. This encasement ensures that no liquid is getting on my mattress. It is made of plastic material and quite thick. It doesn't have any padding to it. It is very similar to a typical, no frills, raincoat. Putti the encasement on my queen size bed was pretty easy. The instructions suggested having two people to do this but I was able to do so myself. I leaned the mattress against a wall and proceeded to encase the mattress. I was able to do so in a few minutes. There is a zipper that closes everything up. There wasn't much noise when I moved around on the mattress but I can feel there was a plastic covering under my bed sheets which doesn't bother much. The plastic encasing wouldn't be able to go in the dryer so it can just be hung dry.

Good mattress cover

The thing I liked most about this mattress cover was that it had a zipper. It keeps the mattress cover from coming off or bunching up. The material feels kind of "crunchy", but once you put the sheet over it, it's fine. My son spilled some water on it, and none of it got through to the mattress. I would recommend this to a friend.

Fit Nice

this Fit Great on my Queen size Mattress and like the info stated it take 2 people to put it on,and with a good sheet set you can barely feel it very happy because when my kids set on it with a drink i will not worry about my mattress,this wipe clean with a wash towel or machine wash and warm tumble dry and has a stronger fabric material

Not so great mattress cover

We bought an old bed frame that came

with a mattress that was in pretty good

shape so we didn't want to throw it out.

We got this zipper mattress cover to

protect from dust mites and other

allergens. Positives - was easy to install

and fits the mattress with room to spare.

Negatives - it feels like plastic covered

paper, it crunches when you like down

and roll around, and it tore when we

were putting it on. We won't be buying

it again.

1. It should work for containing odors-- the fabric itself is virtually odor-free and impervious/waterproof and has fully zipper enclosure, so it should certainly help.
