When you step into the UNiCUBE at Cubehouse, you're stepping onto something that has been used therapeutically for thousands of years. The foot plates inside every UNiCUBE pod are made from Bian Stone — an igneous rock with a mineral composition unlike almost anything else on earth, and a history that predates metal acupuncture needles in Traditional Chinese Medicine.
Most people have never heard of it. Once you understand what it is and what it does, you'll understand why it was chosen for the floor of the UNiCUBE.
Bian Stone — known in Chinese as Sibin Bianshi — is believed to have formed approximately 65 million years ago when a meteorite impacted the Shandong province of China during the Cretaceous period. The intense heat and pressure of that impact fused a unique combination of minerals into a dense, dark igneous rock unlike any other geological formation in the region [1].
The stone is sometimes called "Chinese black jade," though it is mineralogically distinct from jade. Its composition includes quartz, feldspar, and mica, along with up to 40 trace minerals that are considered beneficial to the human body [2].
In ancient China, Bian Stone was regarded as one of the most powerful healing materials available. It was used to massage acupressure points, stimulate meridians, and treat ailments ranging from pain and inflammation to digestive issues and headaches. Historical records suggest it was used as a therapeutic tool before the invention of metal acupuncture needles — earning it the name "the Needle Stone" [3].
What distinguishes Bian Stone from other stones used in wellness practices is that it doesn't just conduct heat — it actively emits three measurable forms of therapeutic energy when warmed.
When Bian Stone is exposed to body heat, it emits far-infrared electromagnetic energy in the 4–14 micrometre wavelength range — the same range the human body itself radiates. Far-infrared rays at these wavelengths penetrate 2–3 inches beneath the skin's surface, warming tissues from the inside out rather than just heating the surface [4].
This deep tissue warming supports microcirculation, encourages vasodilation, and creates conditions that help the body absorb the UNiCUBE's far-infrared heat system more efficiently. The two systems — Bian Stone and the graphene/ceramic heating elements — amplify each other.
Modern laboratory analysis has confirmed that Bian Stone naturally emits ultrasonic pulses — a property that aligns with its historical use as a tool for stimulating acupressure points and meridian pathways [5]. The soles of the feet contain reflex zones that map to every major organ system in the body. The ultrasonic pulses emitted by the warm stone beneath your feet activate these zones passively — no technique or pressure required.
Bian Stone generates negative ions — the same charged particles found in abundance near waterfalls, forests, and ocean coastlines. Negative ions are associated with reduced cortisol levels, improved mood, enhanced cellular antioxidation, and a measurable shift toward parasympathetic nervous system dominance [6].
This is particularly relevant in the context of a UNiCUBE session, which is specifically designed to activate the parasympathetic nervous system. The negative ion output of the Bian Stone foot plates supports that same physiological direction — rest, recovery, and cellular repair.
The placement of Bian Stone in the floor of the UNiCUBE is not incidental. In Traditional Chinese Medicine, the soles of the feet are considered a map of the entire body. Reflexology charts show direct correspondences between specific zones on the feet and every major organ system — the liver, kidneys, digestive tract, lungs, and nervous system all have reflex points accessible through the soles.
By warming the Bian Stone foot plates during a session, the UNiCUBE activates these reflex zones through a combination of heat, far-infrared emission, and ultrasonic pulses. You don't need to do anything. You simply sit, and the stone does the work beneath you.
This grounding effect also has a neurological dimension. The feet contain a high density of mechanoreceptors — sensory nerve endings that respond to pressure, temperature, and vibration. Stimulating these receptors with the warmth and subtle energy of Bian Stone sends a steady stream of calming sensory signals to the nervous system, reinforcing the parasympathetic activation already being driven by the sonic vibration above.
Bian Stone's therapeutic properties are inseparable from its mineral composition. As an igneous rock formed under extreme geological conditions, it contains a complex matrix of mineral crystals and microcrystalline structures that give it exceptional thermal conductivity — it stores heat steadily and radiates it evenly, rather than spiking and cooling like metal or ceramic surfaces [2].
The 40+ trace minerals present in Bian Stone include elements associated with cellular function, enzymatic activity, and tissue repair. While the research on direct transdermal mineral absorption from stone contact is limited, the stone's thermal and emission properties are well-documented and form the primary basis for its therapeutic use.
The UNiCUBE is built around four integrated technologies, each chosen because it amplifies the others:
The Bian Stone doesn't operate in isolation. It works in concert with the vibration moving through the cedar walls, the far-infrared heat radiating from the panels, and the enclosed sensory environment of the pod. Together, these four systems create a bio-energy field that supports recovery at the cellular, neurological, and energetic level simultaneously.

Most clients don't know the foot plates are Bian Stone until after their session. What they do notice — often without knowing why — is a sense of grounded warmth that starts from the feet and spreads upward. Some describe it as the feeling of standing on warm earth. Others notice that their feet feel unusually relaxed, or that the warmth seems to move through their legs in a way that feels different from ordinary heat.
This is consistent with what the stone is doing: emitting far-infrared energy, ultrasonic pulses, and negative ions in a steady, passive stream — without any active intervention required.
Bian Stone's therapeutic properties are rooted in thousands of years of Traditional Chinese Medicine use, supported by modern laboratory analysis of its mineral composition and measurable emissions. The far-infrared, ultrasonic, and negative ion properties have been confirmed through scientific testing.
As with all complementary wellness modalities, Bian Stone is not a substitute for medical treatment. Its role in the UNiCUBE is to support the body's natural regulatory processes — not to diagnose, treat, or cure any condition.
