What does everybody need, young or old, all over the world? It’s SLEEP! Everybody needs sleep! It doesn’t matter who you are, you must rest and sleep well to keep yourself fit to face another day. What you don’t want is to wake up in the middle of the night with an infuriating itch that scratching will only make worse!!

No, it’s not fleas or some allergy – it’s something that is often the subject of old jokes: it’s bed bugs! Bed bug proof mattresses allow you to sleep well at night without waking up in the morning with rows of spots that can be infuriatingly itchy. Bed bugs are not a sign of lack of hygiene or cleanliness and they can be found even in the cleanest of homes. They may not lead to disease, as explained later, but they can be extremely irritating, in all meanings of the word.

Just as irritating to many are allergens such as dust mites and pet dander. This is particularly the case for asthmatics or those suffering other allergies. Bacteria can be another issue as can urine and any other liquids that can get onto your mattress. Here are some ways of preventing such irritations and potential health hazards.

Available in 6 sizes plus a crib size, the Tru Lite Bedding Mattress Protector claims to offer protection against the usual suspects: bed bug protection, dust mites, bacteria, allergens, urine and other liquids.

Mattress Encasement and Bed Bug Proof Mattresses

Bed bugs tend to live in the seams and tufts of your mattress and also in the seams and folds of your sheets. Their eggs are white, as are the newly born nymphs. The quickly become darker as they start feeding, and adults are about the size of a rice grain in a pale tan to orange color.

If they are encased within a mattress or box spring, they will soon die. Some people encase their mattresses or box springs when purchased to prevent the bed bugs from getting into them or beneath the mattress cover. If you prevent the bugs getting into the crevices of the mattress, then it makes it easier to keep the surface of the mattress free of them. However, an encased mattress can still have bed bugs crawling about on the surface of the casing.

One issue noted in reviews is the fact that sometimes referred to as mattress covers, mattress encasements themselves are not bug proof. They are not intended to be. They are intended to prevent bed bugs and allergens already in the mattress from escaping (they die off quite quickly) and from them getting into the mattress from outside. Note that bed bug infestations can occur on top of the encasement or mattress cover. These generally occur under zip covers or in folds in the cover. That’s why they should be washed regularly.

Mattress casings are generally made from hypoallergenic fabrics. These not only give a bad signal to bed bugs, but the best encasements are also repellent to mites and the bacteria which can cause disease if you break the skin when scratching. Note that an encasement covers the entire mattress, while many covers or mattress protectors are fitted like a sheet and do not cover the bottom of the mattress. For that reason, they do not offer 100% total protection.

What is a Mattress Encasement? Buyer’s Guide

A mattress encasement or mattress protector does what it says it does. They are fundamentally the same thing, encasing your mattress so it is protected from the outside. Basically, what is inside your mattress stays there, and what is outside cannot get in. It is a barrier both to living creatures such as dust mites and bedbugs and to allergenic dusts such as pet dander and other dusts. Any bed bugs inside the mattress are locked there and will quickly die.

Most also keep out bacteria and they must also be waterproof to prevent urine and other fluids from contaminating your mattress. One of the issues with mattress encasements is how well they keep out liquids. Many are claimed to be 100% waterproof, yet will allow liquids though if they are left lying on the mattress protector long enough. Others will be resistant to small spillages, but may not resist continued longer spillages or fluid emissions such as urine.

A mattress cover, on the other hand, may not protect the entire mattress. It might only cover the top and sides, but not the bottom. It is important when buying a mattress cover to make sure it does what you need it for. Some people purchase a mattress cover believing it to be a mattress encasement. Some covers are marketed as mattress protectors, although they are not such in the generally accepted meaning of the term. So be careful and check what you are buying.

Guide to Buying Mattress Protectors

What are the important factors to consider when buying mattress protectors or encasements? Well, for starters you must understand what you want it for. That can establish the material you should be looking for. If you want it for domestic indoor use, then go for a polyester or cotton mattress encasement. If you need one for camping outdoors, then something stronger would be better – PVC or polyurethane fiber would likely suit you.

Indoors or Outdoors?

Most people need their mattress protector for indoor use in their bedroom. Cotton or polyester would be good, and it should be water resistant and easily to clean. You should also look for a good zipper or some other method of fixing the protector to the mattress. Zippers on three sides is the most convenient layout.

Zippered, Elastic or Fitted

Zippered covers offer most protection because they are true mattress encasements, encasing the entire mattress and offering maximum protection – keeping any existing bugs or mites inside the mattress in and stopping any others getting it. Check the zipper before buying – some zippers are difficult to use and the zipper tab on others is not covered. You need a good cover over the zipper tab at its end once zipped shut. This prevents moisture, bed-bugs, and mites getting into the mattress through spaces at the pulling tab end of the zipper where there is usually a small space – it only needs to be tiny! If not, then you will have to use some sticky tape to cover it.

Elastic mattress protectors keep the mattress cover in place, but do not generally cover the entire mattress – the base is usually not covered, or only partially covered. This leaves the possibility of dust mites or bedbugs getting under the protector and into the mattress. Elastic covers are never 100% proof to bugs and allergens. The same is true of a fitted mattress cover, but with slightly less protection than the elasticized protector.

Mattress Size: Get it Right

It is important to buy a mattress encasement or protector at the correct size for your mattress. Most come in a range of sizes from cot to California King. Here are the general dimensions of the standard mattress sizes:

• King: 76” x 80”
• Cal King: 72” x 84”
• Queen: 60” x 80”
• Full XL: 53” x 80”
• Full: 53” x 75”
• Twin XL: 39” x 80”
• Twin: 39” x 75

Check the size and the thickness of your mattress. Most mattress protectors and encasements give an indication of the thickness of mattress the product will fit. This often comes in a range, as you will see in our chart above. A wide range indicates that the cover might be loose and move around about a bit at the lower end, while the higher end will be tight. Be careful at the higher end of the range that you don’t burst the seams getting it on your mattress.

Color of the Protector

White might mean cleanliness but you may regret that choice as the mattress protector ages. White looks good in guest rooms, but for a child’s mattress you must go colored if a color option is available. It is not always – most are white. Your own room? Depends on how confident you are!
