The RELAX-FIT mattress is the most advanced model in the Cosmos Bedding Essential Memory range. It combines Visco Active® memory foam, GravitySupport V300® support foam and the CosmoCore V30® core to deliver more precise adaptation, better-controlled support and a more even surface.
It brings together a more responsive memory foam, a more structured support foam and a core designed to maintain consistent firmness. This progression of materials gives better control over sinkage, spreads contact areas and keeps the surface stable as you change position.
Reversible and ventilated, the RELAX-FIT mattress is made in Europe from selected, tested and certified European materials, for a more comfortable wake-up and a fuller sense of recovery.

RELAX-FIT mattress composition
Winter side
A comfortable, structured first touch with AstroComfort®
AstroComfort® fabric gives a premium first feel while leaving the comfort layers free to respond. Sleepers enjoy an even surface that is pleasant to the touch and faithfully conveys the behaviour of the foams beneath the cover.
Progressive, dynamic adaptation with Visco Active®
Visco Active® memory foam moulds to the body and releases more quickly when the sleeper moves. It gradually supports shoulders and hips, increases the contact area and helps limit concentrated pressure points, for a more consistent feel.
A structured, even transition with GravitySupport V300®
GravitySupport V300® support foam prevents an abrupt shift between the memory foam and the firmer layers, improving comfort continuity and stability when changing position.
A stable, resilient surface with OrbitFoam HR35®
OrbitFoam HR35® high-resilience foam helps the cover keep its shape and the surface recover consistently. It supports the upper layers and helps the cover maintain a regular response over time.
Elastic, responsive comfort with Blue Latex®
Blue Latex® encourages natural movement and complements the memory effect with a more dynamic response, ideal for sleepers who want adaptive comfort without losing freedom of movement.
Inner protection with Gravity Interlayer®
Gravity Interlayer® separates the cover from the core, limits direct friction between materials and helps distribute stress, supporting consistent, long-lasting comfort.
Core
A stable, balanced one-piece core with CosmoCore V30®
CosmoCore V30® is the structural base of the mattress. It controls deep sinkage and maintains a constant feeling of support across the whole surface, ensuring stability and consistent support all night long.
Summer side
Protective separation with Gravity Interlayer®
Placed between the core and the summer side, Gravity Interlayer® protects the materials and lets the different layers work more independently, for a cleaner, more even construction.
A summer side supported by GravitySupport V300®
On the summer side, GravitySupport V300® provides structured, comfortable contact that is less enveloping than the winter side, a feel better suited to warmer months.
Enhanced ventilation with Gravity Air 3D®
Gravity Air 3D® fabric has a mesh structure that makes air exchange at the surface easier. It helps wick away moisture and reduces a closed-in feeling, without claiming active cooling. Ideal for sleepers who prefer a more breathable, direct contact.

Essential advantages of our mattress


done Progressive adaptation
The comfort layers follow the body’s contours without an overly deep sinking feeling.
done Controlled support
The core controls sinkage and keeps an even base under the areas that bear the most weight.
done Freedom of movement
The combination of memory foam, support foam and latex makes it easier to change position during the night.
done Reversible
Winter and summer sides let you adjust the sleeping feel and spread wear more evenly.
done Breathable
The 3D fabric summer side promotes airflow and a less enveloping contact.
done European quality
Designed and made in Europe from selected European materials, tested and certified to the applicable standards.
Who is the RELAX-FIT mattress for?
The RELAX-FIT mattress is for sleepers who want an affordable yet highly engineered mattress, with precise adaptation, good stability and a response dynamic enough to move easily. It is especially suited to those torn between a soft and a firm mattress who want a more controlled balance.
Feel and trade-offs
Its more structured construction gives a firmer sense of support than ACTIVEX, AERO and ECO-COMFORT. Those looking for a very soft surface may find it firmer; in return, this stability improves sinkage control and the consistency of support.
European manufacturing, quality control and traceability
The mattress is developed and made in Europe with European materials chosen for their consistency, traceability and ability to fulfil a specific role in the construction. Components undergo quality checks and comply with the applicable European certifications and requirements. This control over origin, composition and assembly allows Cosmos Bedding to offer a more transparent construction than a simple imported product with no full visibility of its materials.
The RELAX-FIT mattress in brief
The RELAX-FIT mattress sums up the Essential Memory DNA: useful, easy-to-understand technology focused on real benefits. Made in Europe with selected materials, it aims for more stable nights, more natural movement and waking up feeling better rested.
