Best Organic Twin XL Mattress Protector

For eco-conscious shoppers, the Nest Bedding Organic Mattress protector provides peace of mind through its organic construction.

Why Buy a Mattress Protector?

A mattress protector will guard your bed from spills, stains, and dust mites. So, you might think that you don’t need one if you keep yourself and your environment clean. The truth is, however, all humans produce oil; we all sweat; we all shed skin cells. All of these things can wear down the integrity of your mattress, cause it to appear dirty, and even void the warranty if it’s bad enough. 

Now, since we’re talking specifically about Twin XL mattress protectors, it’s probably worth discussing two of the primary customers for this size accessory: college students and kids. Not to generalize, but both of these demographics might be more prone to make a mess of their bed—whether they’re munching on messy snacks, drinking coffee while studying, haven’t washed in a couple of days, or all of the above. For these reasons, a Twin XL mattress protector is especially called for.

What to Look for in a Mattress Protector?

It depends on your specific needs. If you’re buying a mattress protector for your child’s bed, or you’re a college student looking to take care of your dorm mattress, we would say that you’ll want to look for a product that is somewhat affordable, waterproof, and machine-washable. 

However, the more money you’re willing to spend the more you can get out of your mattress protector. Some expensive mattress protectors include conductive materials that help draw heat away from your body as you sleep. You also might find that the more you spend, the more luxurious and silky your protector feels. But, for the purposes of a Twin XL mattress, you probably don’t need anything too high-tech.

Mattress Protector vs. Mattress Pad

If you already have a mattress pad and think that means you don’t need a mattress protector, well, you might be right. Typically, a mattress pad’s purpose is to add comfort to your sleeping situation, while a mattress protector shields your mattress from spills, stains, dust mites, and other damaging factors.

There are plenty of high-quality mattress pads that also function as informal mattress protectors because they have hypoallergenic and waterproof properties. If your mattress is new and still has all the support and comfort you need, then a mattress protector is probably the way to go. If you’re looking to add comfort to an older mattress while also shielding it from further damage, consider a mattress pad.
