How Theryn works
3D Airbag compression
Gentle air pressure inflates and deflates around the whole knee, providing a soothing compression massage that helps ease stiffness and improve circulation.
3 Levels · Low · Medium · High
Heat + vibration + red light, together
Carbon-fiber heating warms the knee between 45°C and 55°C while gentle vibration pulses ease pressure and fatigue. Three built-in infrared red-light lasers wrap the joint for deep, soothing relief.
Cordless, simple, certified
Wireless design means no cables when you use it. USB-C charging and a built-in battery give 2–3 hours of use per charge. One touch starts a 10-minute session; it powers off automatically when removed. CE, FDA, RoHS and FCC certified.

What customers say
The warmth wraps the whole knee. It's so relaxing after I've been on my feet all day. Easy to charge and the buttons are simple.
I do a lot of road running and my knees take a beating. This has become part of my recovery routine. Cordless is a big plus.
Wraps snugly around my knee and stays put. Battery lasts a few sessions. Took a couple of uses to find my favorite setting.
Liked mine so much I got one for my father. He's got arthritis in his knees and finds the heat soothing. Simple enough for him to use.
Cheaper than a single physio visit and I can use it whenever I want. The 10-minute timer is handy so I don't overdo it.
