About Us

50 years of Italian manufacturing.
One revolutionary idea.

X-BIO is a brand by Buoninfante Group — an Italian mattress manufacturer founded in 1975 in Battipaglia, Italy.

Five decades of industrial expertise, world-class production and relentless innovation, brought together in a single patented sleep system.

Where it all began

It started on a ski slope.

During a day in the mountains,Enzo Boninfante— CEO of X-BIO —waswearinga technical ski baselayerdesignedtoregulatebody temperature.

"I was struck by how much drier and more comfortable I felt. If thermoregulation helps the body recover during physical activity — why not harness it at night?"

The insight was immediate: a mattress is not just a support surface. It is an active tool for wellbeing. Years of research into sleep science, thermoregulation and material engineering led to the development of the patented X-BIO system.

"With this system, sleep becomes truly restorative. This is where science meets everyday life — and improves it, night after night."

Every X-BIO system is designed, engineered and produced entirely in Italy — with certified supply chains, proprietary production processes and quality standards that have been refined over half a century.

Innovation

We don't just manufacture mattresses.
We engineer sleep systems.

Innovation is at the core of everything we do. We invest continuously in research and development — in materials, processes and proprietary technologies. X-BIO is our most ambitious project: a patented sleep system that actively manages body temperature, humidity and posture throughout the night.

The X-BIO patent is recognised in Italy, the European Union, Japan and Russia — and is currently in the process of being recognised in the USA, China, Canada, Mexico, Brazil and South Korea. The design is registered in Hong Kong, EU, USA, Japan, Singapore, China, Philippines, Vietnam, Taiwan, Malaysia and Indonesia.

No electronics. No noise. No energy consumption.
