Layer Details
Premium Knitted Fabric
A knitted cover with antibacterial and skin-sensitive soft properties. It is the surface you actually touch, so the soft finish matters more than it sounds.
Thermobond Fiber
A thermobond fibre layer sits beneath the cover. It adds a padded feel between you and the foam below.
Two Comfort Foam Layers
Double layers of comfort foam in the quilt plus a high density, durable soft foam layer. This is where the cushioning comes from, with the denser foam helping the surface last.
Pocket Coils Spring
Springs sit in separate bags, which means each one moves independently. Alpha says this lets couples sleep without feeling much of each other's movement.
Foam Encasement
A foam border wraps the spring unit. This supports the edges, so you can use more of the mattress surface without a roll-off feeling.
Felt
A felt base layer finishes the build. It gives the springs a stable foundation to work against.
