Cooler rest,
throughout the night

Ever woken up in a sweaty tangle of sheets? Yeah, not fun.

The Leesa mattress has been designed with a 5cm top layer of premium Avena® foam, which has minimal retention of body heat, and has an innovative airflow system for a cooler night's sleep.

This top Avena® layer works in harmony with the central memory foam layer – delivering all the pressure relief and contouring benefits of memory foam, without ‘sleeping hot’.


Pressure relief
and body contouring

The central layer of the Leesa mattress is 5cm of premium memory foam, to provide body contouring and amazing pressure relief.

Working in harmony with our top Avena® foam layer, you’re able to receive all the benefits of memory foam without the sinking feeling and overheating found in other foam mattresses.


Minimal motion transfer

Sleeping with a restless partner or pet? Or maybe you’re the restless one?

The Leesa mattress has been designed for incredible motion isolation, and produces minimal noise when sleeping partners move and adjust position during the night.


Stands the test of time

It’s important that your mattress continues to support you over time.

That’s why we developed the Leesa mattress with only premium quality foams and conducted rigorous testing (simulating over 10 years of sleep) to make sure your Leesa mattress helps you achieve amazing sleep, night after night.
