Bed Bug Supply Review - see what our experts have to say about this product

Of all the encasement brands we’ve reviewed SafeRest are by far the most advanced and highest quality on the market with full protection against bed bugs, fluids, dust mites and allergens. SafeRest was also tested with live bed bugs and are certified bed bug proof. Encasements are important as they seal off the mattress eliminating potential hiding places where bed bugs may reside. They also prevent bed bugs from escaping the encasement leading to their death by starvation. Another great feature offered by SafeRest is their high quality cotton terry surface material back coated with a breathable waterproof membrane layer, which does not sleep hot and makes no noise. Once installed, you can’t even tell that the encasement has been applied.

SafeRest Encasements offer two features not available on any other encasement. These features include their patent-pending 360° Secure Zipper feature, which prevents the end zipper traveler from pulling back by securing the zipper traveler with a Velcro flap. The other exclusive feature is their advanced Micro-Zipper, which prevents even the smallest infant bed bugs from passing through. SafeRest encasements are also triple stitched to protect the integrity of the seams.

Mattresses today are not cheap and should be protected to ensure years of use. Just one fluid spill or experience can ruin your mattresses, which is why premium encasements should be applied. Those with allergies or asthma will also benefit from the encasements ability to block dust mites and allergens from passing through resulting in improved air quality. Periodically wash the encasement to remove any dust mites resting on the surface of the encasements. SafeRest encasements are also vinyl and PVC free and offer a 10-year manufacture warranty.

Product Information

The first line of defense:

Bed bugs earned their name by being more commonly found hiding on or near the bed than anywhere else in infested homes. Bed bugs feed on human blood while their hosts are sleeping, then hide in a tight and secure place to rest, digest, and reproduce. If left unchecked, a small number of bed bugs with access to a nightly meal can multiply into an infestation in just a few weeks.

SafeRest mattress encasements and box spring encasements are essential to the process of making your bed bed bug proof. Bed bug encasements seal off the mattress and box spring, eliminating those common hiding places that bed bugs use to breed and to avoid treatment efforts.

Rather than disposing of expensive mattress sets, SafeRest bed bug proof encasements can be used to seal off the mattress and box spring, trapping any bed bugs inside and preventing them from escaping. Over time, these trapped bed bugs will die of starvation due to the lack of a blood source.

When designing their encasements for bed bugs, dust mites, and fluid protection, SafeRest selected only the finest materials and developed their own exclusive features. The result was a breathable, noiseless encasement that prevents bed bugs, bacteria, dust mites, and fluids from passing through.

This premium level of protection has helped thousands with allergies and asthma to improve their health by providing a more sterile and allergen free sleep environment. SafeRest encasements have also helped others to protect and treat their mattresses against bed bugs. Finally, those who suffer from heavy night sweating or have children, pets, or incontinence have benefitted from SafeRest's breathable waterproof design, which blocks all fluids from passing through.

Premium Features:

360 Degree Secure Micro Zipper
360° Secure Micro Zipper

SafeRest's patented zipper and enclosure completely seal your mattress on all six sides. The micro zipper spans three sides of the encasement for easy installation and removal.

The micro zipper's teeth that are too small and close together for bed bugs to fit through. The secure velcro enclosure seals off the end of the zipper to ensure there are no gaps that bed bugs can enter or escape through.

Premium Cotton Terry Cover
Premium Cotton Terry Surface

While other encasements use low-cost materials that rustle and retain heat, SafeRest's designers went out of their way to ensure that your sleep experience would be as quiet and comfortable as it would be without a mattress cover.

SafeRest Premium's cotton terry surface design is soft, smooth, and noiseless. Cotton terry naturally absorbs water while allowing air and heat to pass through, keeping your bed cool and dry.

Waterproof Membrane Layer
Waterproof Breathable Membrane

Protect your mattress from fluid spills like sweat and urine with SafeRest's exclusive membrane layer. This unique design blocks any fluids from reaching the mattress while still letting the mattress breathe to prevent heat buildup.

SafeRest's waterproof membrane is free of vinyl and PVC. It has no phthalates or fire retardant chemical treatments. It's perfect for children, allergy and asthma sufferers.

Installing a SafeRest bed bug encasement is very simple, but may require two people since it involves lifting the mattress from the bed. Before you begin the installation, strip the mattress of all bedding, such as sheets and pillows, and remove the encasement from its packaging.

SafeRest Encasement Install, Part 1

With the help from another person, remove the mattress from the bed frame and lean it upright against the wall.

SafeRest Encasement Install, Part 2

Unzip the mattress encasement on all three sides and wrap the short, unzippered side over the top of the standing mattress.

SafeRest Encasement Install, Part 3

Gently pull the encasement down so that both sides of the mattress are covered, and begin closing the zipper.

SafeRest Encasement Install, Part 4

Set the mattress back down on the bed to finish closing the zipper, and use the velcro enclosure to seal off the end of the zipper.

Care and cleaning:

SafeRest's Premium encasements are designed to last for many years if cared for properly. By following the included care instructions, you'll be able to take advantage of all of the protection and health benefits offered by these encasements for the length of their 10-year warranty and beyond.

Note that SafeRest's 10-year warranty covers manufacturing and fabric defects, and will not cover damage caused by failing to adhere to the care instructions.

Wash on warm or hot setting

Wash the encasement with the rest of your bedding at 95° Celsius (200° Fahrenheit), usually reached by the medium or high heat setting of your washing machine.

Dry only on low heat

Tumble dry the encasement only on low heat to avoid damaging it. Temperatures over 55° Celsius (130° Fahrenheit) can melt or warp the waterproof membrane layer.

Do not iron or dry clean

Do not iron or dry clean the encasement. The high temperatures involved will melt the waterproof membrane layer, causing the encasement to no longer be waterproof.

Do not use bleach

Do not use bleach or fabric softener when laundering the encasement. Bleach, detergents containing bleach, and fabric softeners can damage the waterproof membrane layer.

Questions and Answers

Q: I purchased the SafeRest Premium Hypogenic Waterproof Bed Bug Encasements for my mattress, box spring and 4 pillows. Did I purchase the best encasements you sell, and do I need to use poly tape with these encasements?
Asked by: maureen boland - 11/13/2013
You purchased some of the best bed bug encasements on the market, as proven by their bed bug certification from independent research and testing. Instead of using poly tape, we recommend placing ClimbUp interceptors under the legs of your bed to stop bed bugs from reaching you in your bed, as illustrated in step 2 of our 4-step solution.
Q: what are the exact measurements of both the king size bed and the California king size bed?
Asked by: cheryl - 1/26/2015
King sized beds are 76 in x 80 in, and California King sized beds are 72 in x 84 in. If your measurements are off by an inch or so in either direction, the encasements will still fit just fine.
Q: I have a King size bed NOT California KING what are the over all dimensions of the mattress covers?
Asked by: Luis - 3/10/2015
We have both king and California king sizes available, and the dimensions are shown in the bulleted list below the price and size options.
Q: I'm looking to purchase some mattress covers from your company but do not see full size covers. Will you be getting these in stock soon? Thanks, for your help, Brenda
Asked by: Brenda - 3/17/2015
We do have full sized encasements available, but not in every height range. This is due to the extreme rarity of certain bed sizes in those height ranges.
Q: We have a true size queen memory foam mattress that is only 10 in high. We also live in our motor home on a platform bed. Would it be better to get the mattress cover for the box spring, since our mattress is a lot thinner than the 15 to 18 inch mattress cover you are selling for the main mattress? Thanks in advance
Asked by: Sharon - 7/15/2015
We have other heights available, so get the 9-12 inch queen encasement for your mattress as well as an appropriately sized box spring encasement.
Q: can you wash the king size encasement cover?
Asked by: Tom - 8/7/2015
Yes, you can wash and dry using certain laundry settings. Make sure to read and follow the included care instructions.
Q: What is it made of?
Asked by:  - 12/10/2015
Our mattress encasements feature cotton terry cloth on the sleeping surface, polyester sides and bottom, and a polyurethane membrane layer (no vinyl or PVC) under the surface.
Q: Why not have one for a TWIN XL in a 16" mattress? I have two of those.
Asked by: Sheila Ferguson - 4/25/2016
Unfortunately, the manufacturer hasn't released tall encasements for twin XL mattresses simply because they aren't common enough to warrant the production costs.

Fit my 18" Mattress
Having a thick mattress offers and additional level of comfort, but it's not easy to find sheets or more importantly a bed bug encasement for it. This encasement went on easily and fit our mammoth mattress great. The zippers are high tech and the material are high quality. It doesn't make any noise or make us sweat at night. This is a great product!

Swallowed Our 18" Mattress
This was the solution to our thick 18" mattress. We sent this encasement with the help of Bed Bug Supply to our home here in Brazil. It took about 2 weeks to get here, which is to be expected given it was international. The encasement was super nice and we are very satisfied. The zipper was definitely for bed bugs and it is also helping us with our allergies. 5 stars earned.
