UNION Mattress: Bespoke Comfort Engineering
One unique product, three sleep experiences.
At LEONIS, we know that your needs change with the seasons, your body type, or your firmness preferences. Buying a mattress should no longer be a definitive gamble. That's why we designed the UNION: a high-end bedding item, adding a removable and reversible topper to a quality mattress, all designed to adapt to you, night after night.
3-in-1 Innovation: The Choice Doesn't End at Delivery
With a total thickness of 25 cm, this model offers you the generous volume and prestige of a grand hotel bed, combined with unprecedented modularity.
Forget compromises: the UNION is a fused mattress whose top part (the topper) can be flipped or detached as desired. This gives you 3 different comforts in one product. Want firmer support? Need coolness or a more responsive feel? Simply adjust our product to reinvent your nights.
Thermal and Dynamic Feel: Coolness or Invigoration?
Perfectly integrated with the core of the mattress, the 6 cm topper attaches seamlessly to the four lateral handles specially designed for this purpose (two on each side). The true secret to this model's adaptability, it offers two technical sides:
- The Summer Side (Cooling): Equipped with GEL Climaticool foam. It actively dissipates body heat for cool and peaceful sleep, preventing any sensation of overheating in the middle of summer.
- The Dynamic Side (Tonic): Equipped with HR Vitaform foam. Designed for those who wish to avoid the sinking effect, it offers a springy and responsive feel. It accompanies your nocturnal movements with great fluidity while relieving pressure points.
Please note, the different sides can also be used throughout the year: if you are hot in winter or cold in summer, adjust it as you wish (at that time, the topper should be rotated head-to-toe every 3-4 months).
The Support Core: The Absolute Firmness Option
Do you prefer much firmer and more direct support? The modularity of the UNION allows you to completely detach its removable comfort layer. The 19 cm base then takes over. Its central core of HR Bionic Zone foam guarantees firm and rigorous support for your spine, preventing any sagging effect while maintaining absolute elegance.

Care instructions
Mattress/Topper with or without cover:
1. Wash the cover regularly
The cover of your mattress/topper plays an essential role in preserving its cleanliness and freshness. Make sure to wash the cover at least once every two months, or more frequently if necessary. Use warm water and a mild detergent to remove stains and odors. Be sure to follow the manufacturer's washing instructions to avoid any damage to the cover.
2. Use a mattress/topper protector
Even if your mattress/topper does not have a removable cover, you can still protect its surface by using a mattress/topper protector. Choose a waterproof mattress/topper protector to prevent liquid spills, stains, and dirt. Make sure the mattress/topper protector fits snugly on your mattress/topper for maximum protection.
3. Vacuum regularly
Even without a removable cover, you can maintain the cleanliness of your mattress/topper by vacuuming it regularly. Use a vacuum cleaner equipped with an attachment suitable for upholstered surfaces to remove dust particles, allergens, and dust mites from the surface of the mattress/topper. Do this at least once a month for optimal results.
4. Clean stains immediately
If you accidentally spill something on your mattress/topper, act quickly to prevent the stain from setting in. Use a clean, damp cloth to blot the stain gently. Avoid rubbing, as this could push the stain deeper. If necessary, use a stain remover suitable for the type of stain to be treated.
5. Air regularly
To prevent the accumulation of odors and moisture, air your mattress/topper regularly. Remove the sheets and let the mattress/topper air out for a few hours. This will help reduce moisture and eliminate unwanted odors.
6. Rotate the mattress/topper
If your mattress/topper is reversible, rotate it every few months to distribute wear evenly. This will help maintain its shape and firmness.
7. Protect it from pets
If you have pets, make sure they don't scratch or chew on the mattress/topper. Use a special blanket or cover for the mattress/topper if necessary
