Alpha Delta Premium Mattress - UK Double

• 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.
