When it comes to college dorm living, dorm beds are the priority for both planning and comfort.
In this topic, we’re delving into the layers of a college dorm bed and turning those uncomfortable dorm mattresses into a welcoming restful place to sleep.
In our Dorm Shopping & Deal Alerts Facebook Group, one of the the most common group member questions is about the difference between a mattress topper and a mattress pad or a mattress cover or mattress protector or mattress encasement. 🙂 Let’s take a look at how we define each of these mattress “helpers” and which layers you’ll need for college.
Anytime is a great time to learn all about making dorm beds more comfortable, but please don’t start shopping until you are certain of your dorm mattress size. We typically see Twin XL as the most common, but we also see regular Twin beds, Full beds and Full XL beds across the country in college dorms. Your mattress topper, mattress pad and fitted sheet MUST be the same size as your dorm mattress.
Let’s start with the easiest bed layer to differentiate – the mattress topper.
A mattress topper is most typically a 2″-4″ thick piece of memory foam. There are also other materials such as latex or down which are rarely discussed for dorms because of the expense. You may also see a ‘down-alternative’ topper with a couple inches of thickness. Unless you have an aversion to memory foam, these are not a great choice as they tend to go flat, or flatter over time.
Mattress toppers sometimes come with their own cover, usually one that can be unzipped and removed to be washed. This is a nice to have, but not necessary thanks to the mattress pads below.
Rarely, but they’re out there, memory foam toppers have an attached skirt or straps to help keep them in place. The skirt or straps go around the bottom of the mattress.
The thickness of the slab of memory foam is directly related to the price tag. A 2″ topper costs less than a 3″ topper which costs less than a 4″ topper, but don’t let the pricing fool you into thinking that the 4″ is the most premium or most desired.
There are a few exceptions, but dorm mattresses are thin, springy and covered in a thick vinyl that makes them easier to ‘clean’. These mattresses are sometimes referred to as jail cell mattresses, and they just aren’t comfortable. Also keep in mind that they are reused school year after school year. The statistics that I’ve found said that dorm mattresses are used anywhere from 8 years or until they’re pretty much unusable.
It does go over the dorm mattress, yes. Some families choose to put a layer between the dorm provided mattress and their mattress topper. See the mattress encasement section below for more information on that layer.
There is a good bit to learn about toppers before you shop, so the entire next topic is dedicated to explaining what to look for and how to choose a dorm mattress topper.
A mattress pad is a quilted pad that sits on top of the mattress (and mattress topper) and has an elasticized bottom to keep it in place. It can provide some additional comfort but often focuses more on protection (from stains or spills) rather than altering the feel of the mattress like a mattress topper does.
For toppers that do not come with their own cover, you will want a layer between the fitted sheet and the the foam topper to both protect the topper and so that you’re not rubbing directly against the foam through a sheet.
You can choose a standard or waterproof mattress pad depending on the level of protection you choose.
Mattress pads are sometimes called mattress covers, but we will use the term mattress pad throughout the Dorm IQ series and in the Dorm Shopping Facebook group.
I have looked everywhere for a mattress pad made in the USA and have not been able to find one. Just about all are made overseas, primarily in China.
You must look for OEKO-TEX® certified when shopping for a mattress pad to ensure it is free of toxins. I’ve been preaching this for 2 years after reading about the manufacturing practices and toxic materials used in textiles made overseas. The good news is that it is becoming a bit easier to find textiles with OEKO-TEX® certification.
The mattress pad must also have a fully elasticized skirt. In other words, the elastic goes all the way around the ends and sides of the mattress pad, not just in the corners. This will help keep all of the layers from sliding out of place.
The mattress pad in the picture below is the OEKO-TEX® certified Bedsure Mattress Pad, one that we highly recommend. Another breathable, cooling option that also gets great reviews is this Matbeby Mattress Pad.
This SafeRest Waterproof Mattress Pad or this Quilted Waterproof Mattress Pad found at Target are both good options for a little extra protection.
A mattress encasement is a thin but strong fully zippered encasement that goes completely around the mattress. It encases the mattress, providing a full barrier. Mattress encasements are often waterproof, allergen proof and bed bug proof as they can fully seal off the mattress.
This is an optional bedding layer, but many choose to use a mattress encasement to zip away the school-provided used mattress.
PLEASE NOTE: Mattress topper companies recommend against putting your mattress topper inside a fully enclosed encasement as the waterproof, sealed nature could cause mold or mildew to grow. Putting a mattress pad over a topper IS ok as it still allows the topper to breathe. If you choose to use a mattress encasement, you want a very narrow profile encasement to surround the thin (5-8″) dorm mattress. A deeper mattress encasement will leave you with a lot of loose fabric which could cause the mattress topper to slide around above.
The ultra low profile (6″) encasement pictured above on the left is the Hospitology Ultra Low Profile Mattress Encasement. It will stretch to fit an 8″ dorm mattress which my younger son currently has, and my older son used it on a 6″ dorm mattress, and it also fit well on that depth.
Another option that is often at a better price is the Utopia Bedding Zippered Mattress Encasement. Be sure to get the 8″ for a typical dorm mattress.
Mattress encasements are sometimes confused with mattress protectors. Mattress protectors are usually a cross between a mattress pad (without the quilt) and a mattress encasement without being fully encased all the way around – only going around 3 sides like a mattress pad. I recommend against 3-sided thin mattress protectors as you don’t get the quilted benefit of a pad or the full barrier protection of an encasement.
Most dorm mattresses are only 5-8” deep whereas mattresses you have at home are 10”-12” deep. Add a 3” topper to your thin dorm mattress, and you’re at 8-11” deep.
Since your dorm mattress and the topper are a lower profile than a regular mattress, you do not need ‘deep pocket’ sheets. That said, it is hard to find sheets that don’t say ‘deep pocket’ these days. Apparently all of the manufacturers think that is a selling point. Instead, look for the depth of the pocket in the product description. You may see ‘for mattresses up to 15″ deep’ or ‘for mattresses up to 18″ deep. You will be fine with the 15″ depth.
As with the mattress pad, I also recommend that the fitted sheet be fully elasticized to help keep everything in place, not just elasticized in the corners. A snug fit is helpful to keep all of the layers from sliding around on a vinyl covered dorm mattress.
Twin XL sheets are typically marketed as ‘super soft’ college dorm sheets. It is true, those dorm sheets are super soft, at first. They are microfiber, which is polyester, and they are soft and pretty inexpensive. There are 3 issues to be aware of though.
1. Microfiber runs very warm. If your student is a warm or hot sleeper, they will not be comfortable sleeping in microfiber, no matter how soft!
2. Microfiber tends to be very absorbent and can therefore stain more easily. If you’ve seen sheets with darker spots on them, that’s from absorbing body lotions, oils, etc.
3. Microfiber fits well at first but tends to stretch. This can be lead to the bedding layers sliding without a firm hold from both the fitted sheet and the mattress pad.
100% cotton sheets. They sleep cool, they are soft, and they won’t stretch.
There are many options out there, similar to microfiber, but you want to be sure they are OEKO-TEX® certified to avoid toxins in the fabric.
This is a great set of affordable 100% cotton sheets. And if you have a student who doesn’t use a top sheet like mine, you can just buy the fitted sheet!
For an upgraded thread count from this set, the same brand offers these 800-thread count still very affordable sheets. We have these on a few of our beds at home, and they are fantastic! The only problem is that as of the time of the article, they do not come in a Twin XL size.
Now that you know what to look for in each of the layers, this diagram shows how you go about layering a dorm bed.
And that’s it! Follow this layering plan and our size guidelines to ensure your bed will be perfectly made on move-in day and to ensure restful sleep throughout your time in a dorm.
