The 3-in-1 neck therapy device
Tech neck relief with heat, traction, and vibration
Not stretches. Not appointments. Fifteen minutes of targeted relief that fits around your life.
HOW IT WORKS
Three things that actually help you unwind
Most quick fixes rely on one mechanism and fade in minutes. Kaelvi layers heat, traction and vibration together — so relief isn't riding on just one trick.
-
Heat
Soothing warmth to help tight muscles relax — instead of just numbing them.
-
Traction
A gentle, adjustable lift through the neck. Never a hard stretch.
-
Vibration
Soft pulses, not jackhammer intensity. Steady, wave or deep.
How "tech neck" shows up in your day
- You catch yourself rubbing your neck mid-meeting
- You dread checking your blind spot
- Your shoulders creep up toward your ears
- You wake up already behind on rest
- You feel older in your neck than you do everywhere else
Neck pain is more common among office workers than almost any other occupation — published research puts the annual rate as high as 4 in 10 to 6 in 10 office workers.

What people tell us
I use it every evening after work. My neck feels noticeably looser by the time I'm done.
The gentle lift is what sold me — not aggressive traction, just enough to take the pressure off.
Fifteen minutes on the couch and I can actually turn my head without that familiar stiffness.

FAQs
-
How long is a session?
15–20 minutes is the recommended session length. The auto shut-off kicks in at 30 minutes to prevent overuse. Most people use it in the evening while winding down.
-
Will the traction feel too intense?
Thera Neck uses gentle air inflation — not aggressive medical traction. Most users describe it as a mild, comfortable lifting sensation. You control the inflation level and it builds gradually. Start at the lowest setting to get familiar with how it feels.
-
