What is Serene™ Foam?
Serene™ foam is new-age, high-performance polyurethane foam. Serene™ foam comes with advanced Supportive Air Technology, which includes billions of microscopic air capsules that promote airflow, enhance breathability, and increase the support of the bed without compromising comfort.
Each of these tiny cells with microscopic air capsules act as individual shock-absorber cushions, releasing air independently as pressure on them increases for customized comfort and support. Depending on your body type and sleep position, Serene™ foam supports your body while relieving pressure points in heavier sections of the body. Serene™ foam is not temperature sensitive and sleeps cooler than traditional memory foam.
Supportive Air Technology helps in increasing the foam’s level of support as the air capsules release air and conform to the body. Serene™ foam supports the body and evenly distributes weight across the sleep surface leading to pressure point relief, especially in the hip and shoulder areas.
Pros
Body-conforming, pressure-relief
Dissipates heat faster
Isolates motion transfer
 
So what is Avena foam exactly?
Avena foam is a trademarked and patented foam intended to be an alternative to latex foam. It’s been around since the 1990s and it’s designed to have the same overall feel, comfort, and support you get in a latex foam mattress, but with much better overall durability.
Attributes of Avena Foam
Allows for constant airflow throughout the night, so the mattress always sleeps cool
Hypo-allergenic
Won’t crumble or crack
Improved durability over latex
Reduced compression over time (so you won’t develop a “sunk” spot on your mattress)
How is Avena foam made?
Avena foam is manufactured the same way as other mattress foams, it’s poured on a continuous line. Avena is similar to latex in many ways, but uses a different formulation during construction. Avena foam (like latex and virtually all poly foams) is 100% recyclable.
