When recovery feels out of reach, we bring it closer.

When you’re dealing with a concussion, post-surgery pain, ongoing fatigue, or a neurological condition, it’s not just your body that’s affected - it’s your confidence, your energy, and your day-to-day life.
At Cocoon, our role goes beyond delivering at-home Hyperbaric Oxygen Therapy in Auckland. We’re here to listen, guide, and adapt your plan as you go, so you’re never left wondering if you’re on the right track. Recovery isn’t a straight line, but with the right support, it becomes a lot clearer.

Unlimited Sessions. Expert Care. Real Results.

With Cocoon, you get unlimited HBOT sessions at home, tailored guidance from registered HBOT professionals, and a plan designed for your unique recovery needs — without the cost, travel, or scheduling pressure of clinic-based sessions.

Traditional clinics charge $1,500 or more for just 10 sessions. With Cocoon, you can use your chamber every day to accelerate healing and maintain long-term results — while saving thousands.

From your first day, we install your chamber, teach you exactly how to use it and support you throughout your recovery so you always know you're on the right track.

How Hyperbaric Oxygen Therapy Helps Your Body Heal

Hyperbaric Oxygen Therapy (HBOT) works by increasing the amount of oxygen your body can absorb and deliver to cells, tissues, and organs.
Inside a soft-shell chamber, gentle air pressure allows your lungs to take in more oxygen than normal breathing. This extra oxygen fuels your body’s natural repair systems - reducing inflammation, improving circulation, and supporting faster recovery.
