The medium-firm consistency is suitable for all sleeping types while preventing you from sinking in. 

Compared to other high-quality mattress toppers, it’s relatively affordable, which is always a win for us! Its slip-resistant mesh coating and adjustable elastic straps keep it securely fastened to your mattress for a disturbance-free sleep that’ll refresh them for classes the next day.

2. Best Memory Foam Mattress Topper: Tempur-Pedic Tempur Adapt Topper

Memory foam is one of the best materials you can look for in a mattress topper, thanks to its ability to reduce motion transfer. This option from Tempur-Pedic is one of the best. There’s the option for 2- or 3-inch thickness for choice of comfort. Its machine-washable cover is breathable and moisture-wicking, so it’ll take care of any sweat, should it be a hot sleeper. It’s also hypoallergenic to keep it fresh and free of pesky dust mites, and the corner straps firmly cement it to your mattress to prevent slipping and sliding. 

It doesn’t have that new mattress smell when rolled out, so you can immediately put on sheets. It can be a little pricey, especially with the higher thickness, but it might be well worth it so they feel like they’re sleeping on an actual memory foam mattress.

The Specs:

  • Dimensions: 80” x 38”
  • Thickness: 2” or 3”
  • Material: Memory foam 
  • Firmness: Firm

Its anti-slip backing also keeps it in place throughout the night, and the washable cover allows you to keep it in tip-top condition throughout the semester and beyond.

To turn that old dorm bed into that of a high-end hotel, consider this luxurious memory foam mattress topper from the trendy direct-to-consumer brand Saatva. It features three inches of memory foam infused with cooling graphite for ultimate temperature regulation and motion transfer reduction. It’s also made with eco-friendly organic cotton that’s moisture-wicking for even more breathability and natural latex for a buoyant feel, and it’s treated with antimicrobial technology to inhibit bacteria, mold, and mildew buildup. 

It is also the heaviest topper on this list at 24 pounds, so it’ll be a lift on move-in day. But even if they toss and turn throughout the night, there are anchor bands that keep the mattress topper securely fastened to the mattress. Trust us; all their dormmates will be jealous.

Other Twin XL Mattress Toppers to Consider

Nest Bedding Cooling Topper

The Nest Bedding Cooling Topper is decent for its cooling and supportive properties, similar to the brand’s fan-favorite Sparrow Signature Hybrid Mattress. However, it’s pretty pricey for only a two-inch option. Plus, without a washable cover, it can only be spot-cleaned with mild soap. The Nest Bedding Cooling Topper is available at Nest Bedding for $229.

Tuft & Needle Twin XL Mattress Topper

The Tuft & Needle Twin XL mattress topper covers all the proper bases, keeping you cool throughout the night while supporting your joints from all angles. However, without anchor straps to hold it down, you run the risk of it slipping off the bed and needing to adjust it throughout the night. It’s also spot-clean only, making it difficult to maintain for college students particularly. The Tuft & Needle Twin XL Mattress Topper is available at Amazon for $170.

Linenspa Memory Foam Mattress Topper

This memory foam mattress topper with more than 100,000 Amazon reviews is a decent choice for its cushy gel-infused fill that both contours the body and regulates temperature. However, it takes up to 48 hours to air out, requires a separate washable cover, and neither anchor straps nor an anti-slip traction surface to hold it in place while you toss and turn throughout the night. However, it is a good budget buy. The Linenspa Memory Foam Mattress Topper is available at Amazon for $40.99.

Layla Memory Foam Topper

Layla is a reputable direct-to-consumer brand known for manufacturing cooling sleep products, and its popular memory foam topper is no exception. It’s made with copper-infused memory foam that’s both cooling and antimicrobial. However, it doesn’t come with a machine-washable cover, so you’ll have to spot-clean any stains, and it might be too plush for those who require more support while they sleep. The Layla Memory Foam Topper is available on Amazon for $229.

Everything to Know Before Buying a Twin XL Mattress Topper

What to Consider Before Buying a Twin XL Mattress Topper

There are a few considerations when choosing the right Twin XL mattress topper. 

Size: Firstly, confirm the size of the mattress you’re working with. You don’t want your topper to be too long or wide and run the risk of gliding along the mattress. Most Twin XL mattress toppers should be around 80 inches long and 38 inches wide to fit the bed properly.

Thickness: Next, think about the thickness of your mattress topper. Some folks prefer that sinking feeling when sleeping; a thicker mattress topper of at least two inches will offer that. The older the mattress, the wider you’ll want your mattress topper to be, and you can look for something upwards of four inches. 

Material:  Plush memory foam can help contour the body and support proper spine alignment while your student sleeps, while latex provides a sense of bounce and firmness. Gel-infused materials also provide a cooling sensation, preferable if you sleep in warmer climates with a (potentially) unreliable A/C. 

Accessories: Additional features to look for include a machine-washable cover for easier cleaning — because you cannot toss the whole topper in a washing machine. Some mattress toppers have straps to help fasten them to your mattress so it doesn’t budge.

How Long is a Twin XL Bed?

A Twin XL bed measures 80 inches (6.67 feet) long and 38 inches (3.17 feet) wide. They’re the most common in dorm rooms and are best suited for sleepers over six feet tall — which can be common for young adults. While they do not offer any extra width than a standard twin-sized bed, they help account for extra height.

Can a Twin Mattress Topper Fit a Twin XL? 

Because a Twin XL mattress is 5 inches longer than a twin, you’ll want to invest in the right-sized mattress topper when college dorm shopping. A Twin XL mattress topper can stretch over the entire mattress without leaving any gaps for the best comfort and fit with your bedsheets.

Where to Buy a Twin XL Mattress Topper?

Plenty of retailers offer Twin XL mattress toppers, whether in-store or online. They include but are not limited to Amazon, Walmart, Target, Costco, Best Buy, Parachute, Saatva, The Home Depot, IKEA, Wayfair, and more.

How Can You Save on a Twin XL Mattress Topper?

You can save on a Twin XL mattress topper by shopping sales or exploring quality budget options like the Serta ThermaGel Memory Foam Mattress Topper. You can also sign up for Amazon Prime to save on shipping and exclusive members-only deals. Bonus: your Prime membership is half off if you’re a college student. 

You can also sign up for alerts or newsletters associated with your favorite mattress topper brands to stay in the loop about deals. Sales around Prime Day and the Fourth of July would be a great time to shop for this expensive item.
