Setting shapes the session.

The full audible spectrum. Unlike most vibroacoustic devices that only reproduce low-frequency bass (typically 30–100 Hz), Stapes delivers sound across the entire range — from deep therapeutic bass through midrange warmth to clear high frequencies — all through the chair's acoustic wood structure. This means the chair reproduces complete therapeutic music through your body, not just bass vibration with a separate speaker for audio. The frequency response can also be customized to emphasize specific ranges for your clinical protocols.

Therapeutic music isn't just bass tones. Binaural beats require precise frequency control across multiple ranges. Harmonic overtones that create emotional resonance exist in the mid-frequencies. Melodic structures that guide patients through session phases span the full spectrum. Ambient textures that create immersive environments use high-frequency content. If your vibroacoustic device only reproduces bass, your patients are feeling a fraction of the therapeutic content. Stapes delivers all of it through the body.

Yes. Vibroacoustic therapy has been studied in clinical settings since the 1980s, pioneered by Olav Skille in Norway. A comprehensive 2021 review in PMC examined mechanisms across hemodynamic, neurological, and musculoskeletal pathways. 40 Hz gamma-frequency stimulation specifically has been extensively studied by MIT's Picower Institute, with a 2025 double-blind trial demonstrating cognitive improvement through vibroacoustic stimulation. The FDA classifies vibroacoustic devices as therapeutic vibrators. We're transparent that more large-scale studies are needed, which is why we've partnered with JVLMA on ongoing research.

Fundamentally different modality. Headphones deliver sound to your ears. Stapes delivers calibrated vibrations through the physical structure of the chair into your hands, back, and head — you feel the sound through your body via mechanoreceptors in your skin, muscles, and joints. The stereo vibroacoustic field creates spatial immersion that headphones cannot replicate. In clinical settings, this full-body delivery creates a physical "anchor" — particularly valuable during dissociative experiences where patients need to feel grounded and present.

40 Hz corresponds to gamma brainwave oscillations, associated with attention, memory, and cognitive processing. MIT researchers have spent nearly a decade studying 40 Hz sensory stimulation, demonstrating neuroprotective effects and improved brain connectivity. A 2025 clinical trial using 40 Hz vibroacoustic stimulation showed improved cognitive function and reduced depressive symptoms in older adults. Stapes can deliver this frequency through the body — and because of our customizable frequency response, we can emphasize the 40 Hz band specifically for cognitive and gamma-entrainment protocols.

Every chair includes our therapeutic library: relaxation protocols, grounding sessions, focus compositions, gamma stimulation protocols, and ambient soundscapes. All content is developed with Jāzeps Vītols Latvian Academy of Music (JVLMA) — composed specifically for full-spectrum vibroacoustic delivery, with frequency content calibrated for the chair's acoustic properties. Because the chair reproduces the full frequency range, our composers can use the complete musical palette — not just bass tones. Custom programming is available.

Immediately. The full-body vibroacoustic experience is viscerally different from any other relaxation method. Patients feel vibration in their hands, back, and head within seconds of the session starting. Most report deep relaxation within 15 minutes. The experience is memorable — patients talk about it. For sustained clinical benefits, regular integration into treatment protocols is recommended.

Vibroacoustic therapy is generally considered safe for most people. We recommend consulting with a healthcare provider for patients with: pacemakers or electronic implants, pregnancy, acute thrombosis, or conditions sensitive to vibration. Stapes uses gentle, controlled vibrations — not high-intensity exposure. Standard sessions are 15–30 minutes.

No. Stapes vibroacoustic chairs are wellness furniture designed to support relaxation and complement therapeutic environments. They are not classified as medical devices and should not replace professional treatment. The FDA classifies vibroacoustic devices as therapeutic vibrators — a wellness product category. Think of Stapes as purposeful therapeutic furniture: it shapes the treatment environment the way lighting, room design, and sound systems do.

At €5,900, the chair pays for itself quickly. At €150–250 per ketamine session with 3–5 sessions per day, direct revenue covers the investment within 4–8 weeks. Beyond financial ROI: a distinctive treatment environment differentiates your clinic, supports patient comfort, and generates word-of-mouth from patients who feel the difference immediately. The compact form factor also means no room renovation costs.

Absolutely. In-person demos at our Riga workshop. On-site demonstrations at your clinic. Video demonstrations with the Stapes app for international prospects. Pilot placement arrangements for serious prospects. The vibroacoustic experience must be felt to be understood — we strongly encourage trying the chair before purchasing.

Yes. The frequency response profile can be reconfigured as your needs change or new protocols are developed. This is a software-level adjustment — no hardware modification needed. If a researcher wants to emphasize 40 Hz gamma delivery, or a music therapist wants a flatter response for compositional work, or a new therapeutic protocol requires a specific frequency emphasis — we tune it. Stapes grows with your practice.
