Our 360 Lab testers rated the mattress firmness as a 6 to 7. They also said the Leesa feels like you’re sleeping on top of the bed’s surface and that it conforms less to the body than some mattresses with more cushioning memory foam on top, like the Puffy Lux, for example.

Leesa describes the firmness of this mattress as a 6 to 8 (out of 10), which is considered medium to medium-firm.

I determined the Leesa’s firmness level by testing it myself and polling a range of coworkers, to ensure we provide an accurate firmness rating from different types of sleepers. Overall, we ranked the Leesa as a 5.5 out of 10 on the firmness scale, which is just a bit softer than the industry standard for medium firmness of 6.5.

Thanks to its mix of soft and firm foam layers, the Leesa Original offers a medium-firm feel. Mattress firmness is typically measured on a scale from 1 (softest) to 10 (firmest). Based on the level of sink vs. support I felt on this bed, I consider it a 6.5/10, which is the industry standard for medium-firm.
