01 / Sensing
It reads you before it moves.
A three-second body scan maps shoulder position, height and posture before the first stroke, then keeps listening as your body settles into the session.

Precision that
reads you.
Intelligence matters only when the hardware can act on it. Relaxbro translates body data into motion — sensing position, adapting force and shaping each movement in real time.

From specification to sensation
What precision feels like.
02 / Touch
Softness, engineered.
Shore A 45 silicone heads cushion the point of contact, tempering mechanical force with a softer, more resilient feel.
03 / Coverage
It follows the body farther.
A 135 cm SL track carries the mechanism in one continuous path from the neck and shoulders toward the upper thigh.
The system
The algorithm decides.
The mechanism
responds.
Sensing without response is only data. Relaxbro closes the loop continuously — read, interpret, move — so adjustments happen while you rest, not after.
Live feedback
4D core system
01 · Sense
Three seconds to know your frame.
3-sec body scan · 10 ms sensor response
Contour mapping reads shoulder position, height and posture before the first movement — then keeps listening as your body settles.
02 · Adapt
Your body changes. So does the massage.
Real-time bio-feedback · adaptive force control
What the system reads at minute one is not what it reads at minute ten. Pressure, posture and tension are continuously reinterpreted, allowing force and movement to adjust in real time.
03 · Move
Precision you feel, not see.
0.1 mm actuation · 80 mm depth · true 4D
Depth, rhythm, speed and path are coordinated as one motion system, turning mechanical precision into a smoother, more natural-feeling stroke.
Material intelligence
Soft enough to feel human.
A massage head is the final point between machine and body. Flexible silicone around Shore A 45 softens that interface — resilient under pressure, compliant on contact.

Extended coverage
One uninterrupted path,
neck to thigh.
The 135 cm SL track does not stop at the lower back. Its extended curve carries controlled motion from the cervical zone through the lumbar region and into the upper thigh — without breaking the path.

Engineering proof
Precision that survives
repetition.
A mechanism is only precise if it stays precise. Long-cycle reliability testing, abrasion validation and patented engineering are designed to protect performance over time.

Relaxbro Engineering Philosophy
Technology should understand the body
before you notice it.
Your body changes. So does the massage.
That is the point of wellness engineering: sensing that stays quiet, intelligence that keeps adapting, and mechanics precise enough to disappear into the experience.
The Relaxbro Trilogy
Three disciplines.
One chair.
Algorithmic intelligence, precision engineering and artisan craft — every Relaxbro chair is where the three meet.
