Summary: The Lucid Gel Memory Foam Topper is one of the best cheap mattress toppers on the market. It's also one of the best memory foam mattress toppers for both tight budgets and side sleepers thanks to its cheap price and plushness to cushion shoulders and hips. It's also ventilated and infused with cooling gel for enhanced breathability, so it's a good choice if you want to cool down a warm mattress. While it's not the most cooling bed topper around, for the low price you can't fault it. Keep in mind that there's no cover or anchor straps included, though this shouldn't be a problem if you already have a mattress protector and sheet to cover the topper and keep it in place.

Price history: This Amazon-exclusive discount is a stand out when considering that the same topper is being sold at MSRP on the brand's website. It's highest price on Amazon was $129.99 last year, so this deal is one of the best.

What is a cooling gel mattress topper?

A cooling gel mattress topper is a bed topper which has foam infused with cooling gel. The gel dissipates body heat, which then helps to keep sleepers cool if they overheat at night. Many foam mattress toppers are infused with cooling substances, such as graphite or copper.

The cooling gel is usually added to memory foam as this type of foam can trap heat. Gel foam is also used in the top foam layers of the best hybrid mattresses and the best memory foam mattresses, as well the best cooling mattresses.
