The Best Twin XL Mattress Toppers, Tested & Reviewed

Tempur-Pedic is famous for the foam it uses in its mattresses — mattresses that have consistently performed well in our Lab tests for comfort and durability. This Twin XL or Twin Long mattress topper features the same material used in Tempur-Pedic mattresses at a fraction of the cost, so you can improve a worn-down innerspring dorm room mattress. Providing a supportive surface and pressure relief, the topper’s 3 inches of contouring foam slowly adapts to your body shape and provides motion isolation for restless nights.

We love that the topper’s cover can be removed and machine washed should anything spill, and straps are built in to prevent it from sliding around too much, though our tester did note that they experienced some shifting at times. They still found that this topper significantly improved the feel of their mattress and increased comfort throughout the night.

With more than 4,600 reviews on Amazon and an average 4.4-star rating, you can’t go wrong with this Twin XL mattress topper that’ll give any bed an extra 4 inches of height at a fantastic price. We love how easy it is to put on the bed thanks to a design that’s similar to a fitted sheet. We especially like that this mattress topper offers the best of both worlds by combining a layer of gel memory foam underneath a plush, pillow top layer of down alternative that should have you dozing off in no time.

Online reviewers were particularly fond of this extra-comfy combination, preferring it to toppers with a single layer, though some did mention sleeping hot. Should that be the case, keep in mind that the exterior layer is easy to clean and both machine washable and dryer safe.

You can’t swap out your dorm room bed, but you can certainly improve it with Linenspa's mattress topper — and it's well under $100. This bestselling layer of memory foam boasts over 120,000 reviews and a 4.5-star average rating on Amazon, making it a great choice for students heading to college who need a quick solution at a low price. Made of gel-infused memory foam, it should help soften mattresses that are too hard. It's especially ideal for lightweight body types and side sleepers looking to relieve pressure around their joints.

We like that the topper comes in two heights, 2 inches or 3 inches, so you can choose how much added comfort you’ll need. Just note that it comes as a layer of foam by itself, but you can purchase it with a cover for an added cost.

Bring this compact, pillow-top mattress topper along to summer camp or a college dorm to add some extra softness and comfort. While it’s not as dense or supportive as other memory foam mattress toppers and is more akin to a mattress pad, its quilted construction will keep the polyester microfiber fill evenly spread out and comfortable throughout the night.

We like that it’s able to fit mattresses up to 21 inches high thanks to stretchy sides that can be tucked underneath the mattress. Its versatile design, low cost and easy care instructions make this a top pick for anyone who wants to quickly improve the feel of their bed without entirely transforming it. And if you're regularly moving it, you'll appreciate its more compact design.

Memory foam can be notorious for trapping heat, but that’s less of a concern with this breathable memory foam mattress topper from ViscoSoft. Thanks to ventilation in the foam’s design that allows airflow and the addition of cooling gel that’s meant to pull heat away from your body, your risk of overheating throughout the night is reduced. And whether you opt for a 2-, 3- or 4-inch height, you can count on this topper’s foam to offer pressure relief and support. We also like that this mattress topper features a slip-resistant mesh material on the bottom along with adjustable straps to better keep it in place. Some testers noted an initial odor upon opening but this should fade over time.

A Good Housekeeping 2024 Bedding Awards winner, this topper is made from pressure-relieving foam that you'll sink gently into. It’s a great choice for anyone who doesn’t want to add more than 2 inches of height to their bed but does want to add comfort and cushioning to a firm mattress. We like that you can choose between two levels of firmness, luxury firm (medium firmness) or plush (soft), and there are built-in elastic bands to help secure the mattress topper to your bed and keep it in place overnight. Just remember that the cover isn’t removable and cannot be machine-washed.

If your mattress could seriously use an upgrade but you prefer a firmer feel to tons of squish, look no further than this memory foam mattress topper from Saatva. Because it's not as plush as other toppers featured on this list, it's the perfect fit for anyone seeking the conforming feel of memory foam without sinking in too much. This topper adds both pressure relief and comfort while remaining on the firmer side, and it comes with built-in straps to help it stay in place overnight. Just take note that it's spot-clean only and on the pricier side, but a 180-day trial period guarantees a refund should it not be the right fit. "I really felt very well supported on this mattress topper and felt like I slept more soundly and quietly," said one tester.

Just add this topper from Parachute to your mattress to achieve that sleeping-on-a-cloud feel. Filled with a fluffy microfiber fill, it mimics the feel of super plush down that many love. Our Lab experts appreciate the topper's substantial 3-inch fill that feels luxurious, as well as the outer cover's sateen weave that is meant to prevent the fill from shedding. Its baffle box construction also helps keep the fill separated to prevent clumping and shifting during use. Though it's pricier than other picks and doesn't include straps to keep the topper in place, testers gave the topper high scores overall. "The plushness of the topper was superb and pleasantly surprising," said one tester.

Consider a latex mattress topper like this one from Turmerry if you want more bounce and resilience than memory foam as well as some extra breathability. Though the cost of latex materials can often be a bit more expensive, we like the great value this Turmerry Twin XL topper has to offer — without sacrificing quality or comfort. Plus, it has organic certifications by the Global Organic Latex Standard (GOLS) and Global Organic Textile Standard (GOTS) to ensure strict standards throughout the entire manufacturing process.

This mattress topper earned high overall scores among testers for its pressure-relieving, contouring and supportive feel. We also appreciate that you have the choice of various heights and firmness levels so you can find the best fit for your needs. Just keep in mind that some testers did note that this topper can feel heavy to transport.
