Vibroacoustic therapy works on a principle that most people experience intuitively the moment they sit in the Contour Relaxer - that sound, at the right frequency, is not just something you hear. It is something you feel, deeply, through muscle and bone. The TFH Vibroacoustic Contour Relaxer is a full-body vibroacoustic therapy chair designed to translate low-frequency musical vibrations into calming, therapeutic sensory input, available across North America from The Sensory Supply as part of the TFH Somacoustic range.
The popular reclining contour shape has been designed with deliberate ergonomic intention. It distributes body weight evenly across its surface and elevates the knees to support the spine - positioning the user in a fully supported recline that itself encourages relaxation before the vibration even begins. Connected to the TFH Vibroacoustic Resonator Unit (Somacoustic Controller, sold separately), the chair resonates the hertz of the music directly into the user's body at a cellular level. The TFH Resonance Range magnifies musical vibrations so they are felt more easily by the body and less heard by the ear - this is not a speaker system, and the music will be intentionally muffled. The vibration is the therapy.
Key Features of the TFH Vibroacoustic Contour Relaxer
-
Contour Reclining Shape - Distributes body weight evenly and elevates the knees to support the spine, creating a fully supported ergonomic position that encourages relaxation from the moment of contact
-
Full-Body Low-Frequency Vibration - Resonates the hertz of connected music directly into the body, delivering proprioceptive sensory input felt at a cellular level rather than simply heard through speakers
-
Fully Adjustable Vibration Intensity - The amount of vibration is completely adjustable through the choice of music and bass selection, allowing the experience to be customised for each individual's sensory needs and therapeutic goals
-
TFH Resonance Range Technology - Magnifies musical vibrations so they are felt more easily by the body and less heard by the ear, maximising the therapeutic vibration input while keeping the auditory environment calm
-
Compatible with TFH Somacoustic Controller - Requires connection to the TFH Vibroacoustic Resonator Unit (9RSX, sold separately), ensuring the correct amplification is used and the warranty remains valid
Why Vibroacoustic Therapy & What the Research Says
This form of sound therapy was developed in Norway by Olav Skille in the 1980s and has since built a substantial body of clinical evidence. It involves passing pure low-frequency sine wave vibrations into the body through embedded resonance speakers within furniture - and the outcomes are documented. The Food and Drug Administration has approved vibroacoustic therapy for increasing circulation, pain relief, and improving mobility. Research from the University of Toronto and other institutions is ongoing, with vibroacoustic therapy being actively evaluated for conditions including fibromyalgia, cerebral palsy, and Alzheimer's disease.
For occupational therapists and allied health professionals, the practical applications are more immediate: vibroacoustic input delivers proprioceptive sensory input to joints and muscles, supports body awareness and self-regulation, soothes tense muscles, and allows for stretching and strengthening. For individuals who experience sensory overload, the deep, consistent vibration of the Contour Relaxer provides the kind of predictable, full-body input that calms rather than overwhelms the nervous system. And for anyone who simply finds that sitting in a deeply vibrating chair while listening to music is one of the most relaxing experiences available to them - that is entirely valid too.
Vibroacoustic Input for Sensory Integration & Proprioceptive Regulation
Vibration is one of the most direct routes to proprioceptive input - the body's sense of where it is in space and how it is moving. Many individuals who seek sensory input through movement, pressure, or resistance respond profoundly well to full-body vibroacoustic therapy, making the Contour Relaxer a natural complement to other proprioceptive tools in a sensory room or therapy clinic. The adjustable nature of the vibration means it can be used to calm and organise the nervous system or to gently stimulate and engage, depending on the individual's needs at any given session.
Ideal For
- Occupational therapists and allied health professionals equipping therapy rooms and sensory integration clinics
- Schools and early years settings building calm corners or dedicated relaxation spaces
- Hospitals, palliative care environments, and residential facilities seeking non-invasive therapeutic sensory input
- Families creating a home sensory environment for individuals who benefit from deep proprioceptive input
- Any sensory room build where full-body vibroacoustic therapy furniture is part of the therapeutic offering
