What makes Leesa different – and more luxurious – than any other mattress you've tried?
Our Leesa mattress contains a product similar to latex called Avena™, which provides better support than memory foam alone.
We strategically placed a two-inch layer of Avena™ on top of a two-inch layer of memory foam to allow constant airflow for a cooler night's sleep. That's right – a soft, cool mattress all night, every night.
Want a deeper scientific explanation? Sure thing.
Avena™ is considered a latex alternative because it has physical properties similar to latex. For example, latex and Avena™ have a high support factor (also known as compression modulus). In that way, Avena™ outperforms and is different from memory foam. Additionally, both Avena™ and latex have a high resiliency, a measure of the product's "spring" factor. Our 5CM Avena™ top layer sports an Indentation Force Deflection, or IFD, of between 20 and 26, with a density of 50 kilograms per meter cubed.
Want even more science? No problem.
In our testing, Avena™ has generally outperformed various latex grades in the ASTM D1055 Flex Fatigue Test. The percent firmness loss of Avena™ ranged between 5% to just under 10%; various commercially-available latex had firmness losses ranging from just under 10% to more than 25%. Avena™ also has a higher resistance to tearing than latex, when tested to ASTM D3574 Test E.
