Upper comfort and support layers
Aviya lists high-density soy-polyblend foam layers above the coil unit. The published specifications include a 1-inch 20 ILD support layer and a 1-inch 35 ILD firmness layer in its core construction description.
Pocketed coil core
Aviya uses individually wrapped 8-inch, 15-gauge coils and describes a honeycomb spring layout through the middle for lower-back, torso and hip support.
Perimeter foam
The PremiumEDGE design is described as 7.5 inches tall and 3 inches wide using 80 ILD high-density foam around the edge.
Base layer
Aviya describes a 1-inch densified fiber stability base beneath the coil system.
Why construction matters
Construction helps predict feel and behavior but does not guarantee comfort. Learn more in our pocketed coil guide.
