If you're wondering if the Leesa Original Foam 10" Mattress tends to sleep hot, let's break it down a bit. The mattress has a three-layer foam setup that’s meant to keep things comfy and cool.

According to the manufacturer, the top layer is two inches of cooling foam designed to disperse heat, followed by two inches of pressure-relieving memory foam, and a six-inch dense foam base for support. It’s a medium-firm mattress, around a 6-6.5 on the firmness scale, which generally suits all kinds of sleepers—back, stomach, and side.

Our research shows that this cooling foam works quite well for temperature regulation, and many people have mentioned they don’t feel too hot during the night. The open-cell foam technology also helps with airflow.

But, if you naturally sleep very hot, it might not completely solve the problem.

In terms of comfort, side sleepers have found relief from pressure points, while back and stomach sleepers say it helps keep their spine aligned. Plus, couples usually find the motion isolation pretty good, so you won’t be disturbed by a partner moving around.

However, a few things to keep in mind: heavier folks (over 230 pounds) sometimes feel it gets too soft over time, and like many foam mattresses, you might notice an initial off-gassing smell, which usually goes away after a few days.

Leesa offers a 100-night trial period and a 10-year warranty, so you have plenty of time to decide if it's the right fit for you without committing right away.

So, overall, based on both user feedback and the mattress design, the Leesa Original Foam generally doesn't sleep hot. Just keep in mind the possible softness for heavier sleepers and that initial off-gassing smell.
