Composition of the PRIME SPRING mattress

Winter side:

A soft, even first touch with Nebula Knit®

Nebula Knit® is a soft knit fabric that moves with the comfort layers without creating excessive tension on the surface. Pleasant to the touch, it lets the memory foam adapt to the body and transmits the behaviour of the materials beneath the cover.

Progressive, precise adaptation with Visco V200®

Visco V200® memory foam gradually follows the contours of the body and increases the contact area under the shoulders and hips. It helps distribute pressure and limits the feeling of overly concentrated pressure points. Its role is to refine comfort and complement the support provided by the pocket springs.

A stable, even transition with GravitySupport V300®

GravitySupport V300® support foam stabilises comfort and creates a continuous transition between the memory foam and the deeper layers. It limits changes in feel and supports progressive sinkage, preserving continuity of comfort when you change position.

A stable, resilient surface with GravityCore HR35®

GravityCore HR35® high-resilience foam, with a density of 35 kg/m³, supports the upper layers and helps them recover their shape after movement and compression. It helps keep the surface even and preserves comfort over time.

Elastic, responsive comfort with Active Latex®

Active Latex® provides an elastic response that complements the memory foam. Its responsiveness makes it easier to change position and reduces the feeling of being stuck. The sleeper enjoys adaptive contact while keeping good freedom of movement.

Inner protection with Gravity Interlayer®

Gravity Interlayer® separates the cover from the core, limits direct friction between materials and helps distribute stresses more evenly. This intermediate layer protects the construction and helps keep comfort consistent.

Core:

Dynamic, independent support with OrbitSpring® pocket springs

OrbitSpring® is the support base of the mattress. Its pocket springs respond individually to the body's pressure, limiting motion transfer from one side of the bed to the other. The suspension gives a dynamic response under the back and hips, makes changing position easier and leaves room for air to circulate inside the mattress.

Summer side:

A protective separation with Gravity Interlayer®

Placed between the core and the summer side, Gravity Interlayer® protects the materials and limits direct friction with the suspension. It helps maintain an even construction and a consistent reversible surface.

A summer side supported by GravitySupport V300®

On the summer side, GravitySupport V300® ensures a smooth transition to the core and avoids overly direct contact with the suspension. The sleeper keeps good continuity of support, with a feel that is generally lighter and less enveloping than the winter side.

Surface ventilation with Gravity Air 3D®

Gravity Air 3D® fabric has a mesh structure that makes air exchange at the surface easier and helps moisture escape. It complements the internal ventilation of the pocket-spring core and offers a more breathable contact, suited to sleepers who prefer a less enveloping summer side.
