If you find yourself tossing and turning during the night, a mattress topper can help to make your bed much more comfortable — but ones that fit twin XL-sized beds can be hard to find. To find the best twin XL mattress topper for you, consider your unique sleeping preferences and choose a material (whether that be memory foam, latex, or down alternative) and thickness that aligns with that. You’ll also want to ensure that the topper you go with is designed specifically to fit this extra-long bed length; twin XL beds are 80 inches long, aka about 5 inches longer than a typical twin.

When picking out a mattress topper, weigh the upsides and downsides of each material option. Memory foam mattress toppers are a popular choice, since the foam hugs your body to provide comfort and support while reducing pressure on your joints. Memory foam tends to retain heat though, so if you’re a hot sleeper look for a cooling design that contains gel or has an open cell design to allow for better ventilation. If you’d prefer a firmer mattress topper, latex is the way to go, and since you won’t sink into the latex, it won’t feel as hot as foam. The downside? Latex mattress toppers tend to be pricey. Finally, if you prefer a soft and fluffy feel, consider down alternative mattress toppers which are typically budget friendly and often machine washable, unlike memory foam and latex picks.

In terms of thickness, memory foam and latex mattress toppers are commonly found in 1- to 4-inch options. If you want to drastically ​​change the support offered by your mattress, opt for a thicker pick, but know that these often cost more than thinner ones. Down alternative mattress toppers don’t always provide information about thickness, but you can get an idea of how plush each pick is by comparing the number of ounces of fill or by reading customer reviews.

Scroll on for six twin XL mattress toppers to improve the comfort level of your bed — and they all cost less than $175.

1. A Popular Gel-Infused Memory Foam Topper

This mattress topper from Sure2Sleep is super popular on Amazon — it has a solid 4.6-star rating overall, after more than 21,000 reviews — and it’s likely because it boasts your choice of 2 or 3 inches of memory foam that’ll conform to your body as you sleep. Another major plus? This pick features breathable open cell construction and is infused with gel that’ll help prevent you from overheating throughout the night. The twin XL size of this topper measures 79 inches in length, but it’s also available in twin, full, queen, king, and California king sizes.

Enthusiastic Amazon review: “Really made a huge impact on my sleep quality. I purchased a firm bed about 2 yrs ago but it started to dip a little and I've been left pretty achey from the lack of support. I ordered this to try and soften up on my pressure points and I can't say enough good things. It is cushy soft but still provides support.”

2. A Fan-Favorite Down Alternative Mattress Topper

With 30 ounces of fluffy down alternative filling, this mattress topper from EASELAND will feel like sleeping on a cloud. But don’t just take my word for it, this pick boasts a stellar 4.6-star rating overall on Amazon after more than 48,000 reviews, a true testament to its comfortable construction. The plush mattress topper is 80 inches long and is designed to fit twin XL mattresses that are up to 21 inches deep.

Enthusiastic Amazon review: “This mattress cover exceeded my expectations by far! The comfort is comparable to sleeping on a cloud or a thick, fluffy comforter. The best I can explain is that it adds a smooth extra layer of comfortable extremely soft fluff between you and your mattress.”

If you find yourself in need of extra cushioning, the topper is available in 2.5- and 3-inch styles for a little bit more.

I've used it for about a week now, and I am having my best sleep ever!”

It feels springy like it's really pushing up and supporting your body on every point.”
