Looking for an Sofa Mattress Protector?

FREE ground shipping!

Did you know? Ordinary sofa mattress protectors only protect the top of your mattress. Why settle for just the top?

Our Sofa Mattress Encasement zips all the way around your mattress protecting it on all 6 sides!

Similar to our mattresses, this encasement can be made to almost any size or shape! If you don’t see your size listed, contact us for more information!

Protect Yourself Against Dust Mites!

Dust mites can cause asthma, allergies, rhinitis, and eczema. They live on the millions of skin cells and body fluids that our bodies secrete each night while we sleep.

Our sofa mattress encasement seals out dust mites and prevents any other allergens from coming into contact with your mattress!

Why Don’t Regular Protectors Work?

The fitted sheet style sofa mattress protectors only cover 25% of your mattress, leaving you exposed to irritating allergens.

Our 6-sided sofa mattress protector completely zips around your mattress to lock out dust mites and allergens!

It works so well that many of our customers leave their mattress encasement on their mattress during the off-season to give it an extra layer of protection!

100% Stain and Waterproof Guarantee

Using our mattress encasement guarantees no fluids or stains will make contact with your new mattress!

In fact, if you purchase a mattress encasement and a mattress from us at the same time, we offer you a lifetime warranty against spills and stains. If a spill or stain that goes through the encasement and on to our mattress and a professional cleaning company can’t get the stain out, we will replace our mattress with one of equal value for free!

Protect Yourself Against Bed Bugs!

The exclusive zipper lock system and our unique fabric has been lab tested to be bite and entry proof.

This creates a fortress of protection around your mattress that works much better than a fitted sheet style mattress protector.

Love the sleepsofa mattress
I finally had the chance to try out my new organic mattress during the Thanksgiving week. My guests thanked me profusely for making the switch. I also purchased your queen sized contour sheet instead of using a conventional sized sheet. No more slipping off at the corners. It was a snug and perfect fit. So glad I found your products!

What a great company for customer service. I am also in the retail business and I really appreciate top-notch service. Jonathan and Brittany are great. I would strongly recommend this company.

I have ordered a mattress and mattress cover and I am very happy with what I received. The quality of the items are excellent and the price was very fair. I will continue to use for similar purchases.

easy to install; great peace of mind
The mattress encasement was easy to put on and gives me the peace of mind that my custom mattress (also bought through mattress insider) will stay in good condition, safe from wet and dirt accidents. I use the mattress for car camping in my Honda Element.

Comments after purchase…
As we say down here, "y'all are great!". Jonathan called me on my cell to let me know my order had shipped. He(the owner) gave me his ph# in case there were any problems. I've never had this happen. Great company! We had bedbugs. We treated w/a very good product, encased our mattress and haven't seen anything since, Well, a few dead bedbugs! Thx, "y'all are great!

It makes sense to protect this mattress and given if, ordered at the same time as the mattress then there is written lifetime warranty.

I often travel with a couple dogs. They can be wet and dusty. I figured protecting the mattress is a good idea.

Difficult to fit sleeper sofa mattress.
Elizabeth L on Jul 3, 2018
The sofa bed will not be used regularly and I was concerned with (Yuk!) what might drop down under the cushions between uses. The encasement can be dry-cleaned before each use providing a more healthful environment for our guests.
James D on May 31, 2018
Seems like the best choice in the size I needed(64×72). Also, made in USA.
Joseph M on May 27, 2018
I have ordered this item for a twin mattress and it's wonderful quality and fit.

Joleen M on Apr 30, 2018
Since I have kids who use the sofa sleeper for sleepovers, I selected the encasement to keep the mattress stain free and dry.

andrey g on May 7, 2017
We could not order an all encased sleeper sofa mattress cover from anywhere in stock; would be months and I need it within 1 to 2 weeks. A hard item to find. Although they would be half the price; if you could find in a store or through an on- line source. The reviews were good for your company. I also like it is made in USA.
Deborah L on Mar 25, 2017
Old spring sleeper sofa mattress had mold from spilled liquids that reached the mattress.
TIMOTHY A. on Mar 19, 2017
A wet mattress (cat urine of all things) is why we're replacing our sofa mattress. So protecting that investment with a waterproof encasement just made sense. The mite/dust protection was attractive too.
Mark R on Mar 5, 2017
It had the best reviews and yor site was the only that spoke of how often it was goin to be used ans if people in ny use it daily then it has to be good can't wait to get it

Will the encasement materials cause a person to feel warmer during sleep?
Rebecca O on Sep 25, 2017
BEST ANSWER: Hello Rebecca,
The mattress Encasement is made of a breathable polyurethane mix material and should not make you feel warmer during sleep.
Kind Regards!
can i machine wash on delicate cycle this mattress cover?
A shopper on Oct 9, 2018
BEST ANSWER: Yes, I wash mine all the time. I use the cold cycle and I also put it in the dryer on low-medium setting. Hope that’s helps.
What are the cleaning instructions?
A shopper on Jul 19, 2017
BEST ANSWER: To clean the mattress encasement, simply remove it from the mattress and take to your nearest dry cleaner.

Kind Regards!
How thick of a mattress will this cover?
A shopper on Mar 26, 2017
BEST ANSWER: We can customize our encasement to just about any dimension you need!

Feel free to give us a call to discuss!
What material is this mattress case made out of? I prefer cotton over synthetic material.
Nancy N on Sep 26, 2016
BEST ANSWER: Hello Nancy,

The mattress encasements are made of a polypropylene-mix material so would be considered synthetic. This enables the encasement to waterproof your mattress.

Please feel free to contact us with any further questions.
