This mattress topper softens dorm beds for $46 with promo code — but twin XL is selling fast
Memory foam mattress toppers add a softening, hygienic layer to hard, over-used dorm beds — but they can often be too expensive for student budgets or too thin to make any real impact on an uncomfortable mattress. However, a Lucid Gel Memory Foam Mattress Topper in a twin XL, now from $45.05 (was $52.99) at Lucid with code BETTERSLEEP15, is ideal for adding "cozy contouring" at an affordable price.
Our lead tester was impressed with its soft feel and surprisingly good temperature regulation. The mattress topper is available in three heights (2", 3", or 4"), with our reviewer testing the thickest option and praising its ability to "transform the firmest bed into a plush paradise". With its cradling foam cushioning shoulders, hips, and knees, we think it's a great choice for side sleepers.
While you can find some cheap picks in our best mattress guide that could make good dorm mattresses, a mattress topper is a much more cost effective solution.
The Lucid Gel Memory Foam Mattress Topper is a particularly good dorm room choice, as it features in our 2026 best mattress toppers guide as our favorite budget option. We've also picked it as the best deal under $50 in this month's mattress sales.
"Cozy contouring" for rock-hard dorm beds
Dorm beds are notoriously uncomfortable and thin — not to mention on the grubby side. So you'll often find a mattress topper on a college dorm checklist. Our best mattress toppers for college dorms features the Lucid Gel Memory Foam Topper as the best budget option thanks to its under-$100 price tag for twin XLs.
Now, as an affordable option, it does skimp on some features that you'd see in more luxurious mattress toppers. For example, there's no cover or state-of-the-art cooling tech. But despite lacking those features, our Lucid Gel Memory Foam Mattress Topper review rates it highly for its value for money.
For instance, our lead reviewer credits the "ventilated design for propagating the airflow so that we slept comfortably, no matter how warm or cool the room was."
As for comfort, the 4" version gives some of the best mattress for side sleepers a run for their money as our testers said "it provided cozy pressure relief to the shoulders and knees in that position."
