"I'm 59, drove trucks for 25 years. Sitting in a cab all day is basically a recipe for sciatica. Tried the chiropractor, the injections, every cushion and brace you can buy. Nothing lasted more than a few days. Tried this because my physio wasn't taking me anywhere. Two weeks in I did a four-hour drive and got out of the cab without standing there waiting for my back to let me move. First time that had happened in years."

You've Done Everything Right. So Why Does Sciatica Keep Coming Back?

You know that first moment in the morning. Before you even move. That half-second where you're lying there and you don't know yet if it's going to be a good day or a bad one.

Then you go to swing your legs out of bed. And there it is. That shooting pain down your leg. The burning.
That electric feeling all the way into your foot. You grab the nightstand and think: here we go again.

You've been to the chiropractor.
Felt better for two days, then the pain came right back like it never left. You've tried the injections. The pills. The heat pads. The YouTube stretches at 11pm when you couldn't sleep.

You've spent more than you'd like to admit. And you're still here.

And somewhere along the way you started wondering: is this just my life now?

That fear is real. It's not weakness. It's what happens when you've been in pain long enough to start losing hope.

Here's what we want you to know: you're not broken. And you're not out of options.

 
 

Don't Take Our Word For It.

"Worked construction 40 years. Sciatica had me waking at 3am, burning pain shooting to my foot. Tried chiropractors for years and the relief lasted a few days, then came right back. My daughter ordered this without telling me. Six weeks later I slept through the night for the first time in years."

The Real Reason the Chiropractor Never Fixed It.

The chiropractor wasn't wrong. Creating space between your vertebrae and taking pressure off the nerve is exactly what your back needs.

The problem is timing.

They decompress you on Tuesday. You drive home, sit, sleep. By Thursday your spine has compressed right back and you're booking another $120 appointment.

Same with heating pads. They warm your skin. They don't reach the nerve. TENS machines mask the pain signal. The moment you take them off, it comes right back.

Your sciatica keeps coming back because your spine gets compressed every single day. And until now, you had no way to reverse that every single day.

That's the gap. That's what RelaxiCore™ was built to close

Three Therapies. One Sequence. Engineered to Work Together.

We didn't start with a lab. We started by listening to people who had been failed by every option they tried.

What we kept hearing was that nothing worked on its own.

Relief required three specific things happening together. Nobody had built that into one device.

So we did.

RelaxiCore™ is engineered to deliver all three in the correct sequence, in the same 15-minute session, every day.

Step 01 Vertebral Decompression

The device lifts your lower back at a precisely calibrated 26-degree angle. This is the angle at which the posterior spinal ligaments reach optimal tension, creating maximum separation between the vertebrae without straining surrounding tissue.

As that space opens, the disc that has been pressing against your sciatic nerve begins to retract.

A clinic does this once or twice a week. RelaxiCore™ does it every day. Daily decompression is what changes the pattern instead of temporarily interrupting it.

Step 02 Therapeutic Heat Infusion

A surface heat pad reaches skin temperature in minutes. The tissue around your spinal discs sits 2-4 centimetres deeper than that. Surface heat never arrives.

RelaxiCore™ delivers sustained therapeutic heat directly against your lower back while your spine is already in a decompressed position. That timing is the key.

With the vertebrae separated and the disc retracted, blood vessels in the surrounding tissue have more room. Heat dilates them further. Oxygenated blood, fluid and nutrients flow into the disc and the inflamed tissue around the nerve.

This is how real disc recovery happens. Not through a heat pad on top of a compressed spine. Through heat delivered to a spine that has just been given room.

Step 03 Neuromuscular Release

This is the step no single other therapy addresses. And it is the reason that even people who go to a good chiropractor regularly find themselves compressing straight back within hours.

When your back has been in pain for months or years, the muscles around your lumbar spine have been in a state of chronic protective contraction. They are locked. And locked muscles actively pull your vertebrae back toward compression the moment any other therapy ends.

RelaxiCore™'s vibration element runs simultaneously with decompression and heat. The rhythmic stimulation travels through the soft tissue into the muscles themselves, triggering the tonic vibration reflex, the same neurological response a physiotherapist uses manual techniques to achieve. Muscles that have been contracted for months begin to release. The spine holds its decompressed position instead of springing back.

This is why relief from RelaxiCore™ builds with daily use instead of resetting. The muscles learn, session by session, that it is safe to stay relaxed.

Three therapies, chained in the right order, at the right time, every single day. That is why this works when everything else only worked for a while.

  • 1. Spinal Decompression

    Creates space between compressed vertebrae. Takes the pressure off the nerve causing the shooting pain down your leg.

  • 2. Deep Heat Therapy

    Delivers heat deep into the tissue, not just the skin. Drives blood flow and nutrients to discs that have been starved for years.

  • 3. Vibration Release

    Releases the muscle tension that has been pulling your spine back into compression every time another treatment ends.

"Sciatica shooting down both legs for months. Couldn't walk, couldn't sleep, couldn't sit through a meal. Tried everything. Used this twice a day for four days and by day three I slept five hours straight. I keep waiting for it to come back like everything else did. It hasn't. Worth every penny."
Diane W., 67 |  Texas, US
"Had sciatica for three years. My GP kept fobbing me off. Tried physio, injections, nothing lasted more than a few days. Saw this on Facebook and thought it was probably rubbish. Bought it anyway because I had nothing left to try. Two weeks in I slept a full night for the first time in I don't know how long."
Sandra T., 61  |  Manchester, UK
"My dad had been suffering for months. He stopped coming on our Sunday walks. Stopped getting down on the floor with the grandkids. I ordered this without telling him. He called me a week later and said he didn't know what that thing was but he'd slept four hours straight. He's back on our Sunday walks now."
James C., buying for his father aged 71  |  Ohio, US
 
 

Here's What People Tell Us Changes First.

Mornings

You wake up and lie there for a second. And the shooting pain isn't the first thing waiting for you.

You swing your legs out of bed without bracing yourself on the nightstand. You walk to the bathroom like a normal person.

Standing Up

You stand up from a chair without wincing. You stop doing that slow painful crouch on the way up that became so automatic you forgot it wasn't normal.

Getting In the Car

You just get in. No repositioning at every red light. No cutting the trip short because you can feel it building.

Sleep

You stop dreading going to bed. You find a position and you stay there. No waking at 3am with your leg on fire.

Customers tell us this is the one that gets them emotional. Not walking further or skipping the chiropractor. Just sleeping through the night.

Your Head

You stop planning every day around the pain. You stop thinking about your back every hour. You just live.

Most People With Sciatica Spend Over $3,000 a Year. And Still Hurt.

Here's what most people spend before they find something that actually works:

Chiropractor: $80-150 per visit, 2-3x per week. Relief lasts 2-3 days.

Steroid injection: $150-400. Partial relief for 4-6 weeks. Often nothing.

Physical therapy: $75-150 per session. Insurance fights you every step.

Heat pads, TENS machines, braces, cushions: drawers full of them.

A typical year of managing sciatica: $3,000-5,000. Same pain at the end of it.

RelaxiCore™ is $89.99. One time. Use it every day for as long as you need it.

 
 

Our "Feel Relief or It's Free" Promise

You have probably spent money on things that promised relief and delivered nothing. Heat pads that barely warmed up. Cushions that went flat. Gadgets that collected dust. We get it.

That is why every RelaxiCore™ comes with a no-questions-asked 60-day money-back guarantee. Use it every day. Put it through its paces. If you do not feel meaningful relief in your back and legs, just email us at support@kavirae.com. Full refund. No hassle. No hard feelings.

Why can we offer this? Because less than 5% of customers ever ask for a refund. Most are too busy enjoying their pain-free days.

 
 

Your Questions, Answered

Most people feel relief within the first 15-minute session. For lasting results, use daily for 6-8 days. 94% of clinical trial participants reported significant improvement in their first week. This is not a quick fix that masks pain. You are addressing the root cause, so consistency matters.

Your skepticism makes complete sense. Here is why those treatments did not give lasting relief: they each only address one part of the problem. Pills mask pain. Chiropractors adjust you, but muscles pull everything back. Heating pads warm the surface. Physical therapy helps, but you cannot afford 3 sessions a week forever.

The RelaxiCore delivers all three therapies your body needs: decompression for the nerve, heat for disc healing, and massage for muscle tension. All at once. Every day. At home.

The RelaxiCore was specifically designed for sciatica sufferers. Sciatica happens when something pinches your sciatic nerve, usually a bulging disc or compressed vertebrae. The decompression creates space between vertebrae, taking pressure off the nerve. Many users report leg symptoms improving before their back pain does.

You can use it on the floor, a firm bed, your couch, or even in your office chair. Many customers use it throughout their workday for continuous relief. It is discreet, quiet, and fits most chairs perfectly. If getting on the floor is difficult, the bed works just as well.

The RelaxiCore is designed to be gentle. It simulates the kind of light traction and warmth you would get at a physical therapy session. There is automatic shut-off after each session and overheat protection. It will not burn you. However, if you have a pacemaker, recent spinal surgery, or a serious medical condition, please consult your doctor first. We want you safe and informed.

Every RelaxiCore is built with an industrial-grade motor and durable exterior. It is tested to withstand thousands of hours of use. If anything does go wrong within 60 days, we replace it immediately at no cost. Our latest units have upgraded batteries and proper charging adapters included. We listened to early feedback and fixed those issues

We understand. Facebook is full of junk products. Here is what should reassure you: 16,798 verified reviews with a 4.8 average. Tested in 50+ chiropractic clinics. Manufactured in an FDA-registered facility. And a 60-day money-back guarantee that scam products never offer. If we were not confident, we would not let you return it.

No batteries. The RelaxiCore uses a USB-C cable that plugs into any standard outlet or USB adapter (like your phone charger).

Email support@kavirae.com with your order number. We will promptly refund your purchase. No hassle, no hard feelings. We offer this because less than 5% of customers ask for a refund. Most are too busy enjoying their relief.
