How it works
Strap one below each knee, tap once and pick your level. A 15-minute session of targeted vibration crowds the crawling signal out, then fades on auto shut-off. Most women are asleep before it ends.
What's in the box
2 devices, 2 fitted straps, 2 spare straps, a USB-C cable, the printed quick-start card, and The Restless Legs Guide emailed the moment you order.
I used to start dreading the night at about 6pm. Three weeks in and I get into bed like a normal person. It’s the headspace more than anything, I hadn’t realised how much of my day was going on worrying about it.
Who this is for
If your legs start the second you lie down.
Not a sleep aid. Not a massager. A way to answer the crawling without getting out of bed at 2 a.m.
“Restless legs in third trimester is pure torture.”Erin, 31 · 34 weeks
“I cry in bed at 3 AM because my legs are driving me crazy.”Kayla, 28 · third trimester
“My OB told me I can’t take any RLS medications while pregnant.”Nicole, 29 · 28 weeks
Why it works
Give the nerve something real to feel.
As you wind down, the brain chemical that filters leg sensation dips and overloaded nerves start reporting movement your legs are not making. Fast vibration signals reach the spinal cord ahead of those slow crawling ones and crowd them out — the same reason rubbing a knock makes it hurt less.
The catch has always been delivery. Pacing works but costs you the night. A pad under the mattress moves when you move. You need the input on the muscle, staying put, while you lie still.
Ten seconds to set up
Strap. Tap. Sleep.
Strap
Wrap one below each knee, snug like a sock cuff. No buckles, adjusts to every calf, works over bare skin or leggings.
Tap
One button, three modes, five intensities. Start at level 3 and adjust until the urge softens. A calm hum, never a jolt.
Sleep
The 15-minute session fades out on auto shut-off. Most women are asleep before it ends, and it is inaudible to your partner.

What actually changes
Evenings that are yours again.
What perinatal clinicians say
Counter-stimulation is the first thing we suggest.
“Restless legs is one of the most common complaints I hear in third-trimester visits, and our options are limited — most medications are off the table. Movement and counter-stimulation are exactly what we recommend. A drug-free device that delivers it in bed is the version patients actually stick with.”

KAIRA Still is a wellness device, not a medical treatment, and makes no claim to cure or treat any condition. If you are pregnant, show it to your provider first.
No dodging
The four things stopping you right now
You should be. Most of what gets sold to pregnant women for this is a lotion with a promise attached, and we bought our share of them first. This is not something you rub on and hope. It is mechanical, you feel it the first time you switch it on, and you know inside one night whether it does anything for you.
It is not a massage device. It targets the gate-control mechanism — the same principle behind every device cleared to treat restless legs, and the reason walking helps. What is new is delivering it to the muscle while you stay lying down.
It is worn over the skin on the calf: external, mechanical, nothing ingested or absorbed. We are a wellness device and not your clinician, so show it to your OB or midwife first. Most are familiar with counter-stimulation.
For a lot of women it does fade within days of delivery — and for plenty it does not, it carries straight into the fourth trimester. Either way you are being asked to write off the last weeks of your pregnancy and the first weeks with a newborn, which is precisely when running on nothing costs you the most.
You are not failing at a skill. Third-trimester iron demand and shifting hormones turned up the volume on a nerve signal — that is physiology, not toughness. Nobody hands out a medal for enduring it quietly. We know, because we tried to earn one.
The motor sits below the noise floor of a duvet. From the other side of the bed it is inaudible — and unlike getting up to pace, it does not move the mattress.
It is $69.99 per leg, once. A month of magnesium plus compression socks plus a mattress pad runs past that in the first quarter and keeps running. You buy it once, and the spare straps are already in the box.
The strap is one-size soft velcro with a wide adjustment range, designed to fit through pregnancy swelling and after. If it does not fit you, that is covered by the same 60-day guarantee.
No small print

The whole hallway thing just stopped
I was doing four trips down the hall most nights by 34 weeks. Now I put them on as soon as I feel it starting and honestly I’m usually out before the timer finishes. My husband noticed before I did, he said I’d stopped kicking him.
Took me three nights to get it right
Level 3 is my setting. The first two nights I had it way too low and thought ok, this isn’t doing anything. So if you’re about to give up on it, turn it up. Since I sorted that out, evenings on the couch are mine again.
Nobody told me it can stick around
I assumed mine would go when she did. It didn’t. These get me through cluster feeds, I can actually sit still with her on my chest instead of jiggling my leg for an hour and waking her up. That on its own was worth it.
Showed it to my midwife first
I bought them at 31 weeks and I wasn’t going to use anything without asking first, that’s just me. Took them to my next appointment, my midwife had a look and said it sits on the outside of your leg so it’s not really her department. Felt a lot better having asked.
My husband actually ordered it
He was fed up of getting kicked at 2am and I was fed up of saying sorry. Bit embarrassing that a small purple thing sorted out something we’d been bickering about for months, but here we are. We both sleep now.
Second baby, wish I’d had it for the first
With my son I just white-knuckled it for two months. This time I’ve had them since about 30 weeks. It starts in both calves for me so one would never have cut it. My sister ended up ordering a set after watching me use them at Christmas.

Not pregnant, still needed it
Wish I’d found this in my second trimester instead of my third. Not much else to say really, it does the job and I’ve stopped dreading bedtime.
Long flights are survivable now
Bought it for the pregnancy and then ended up using it most on a nine hour flight. Had one on under my leggings, nobody heard a thing, didn’t have to walk the aisle once.
Great at home, bulky for travel
Does what it says and the battery lasts me all week. Only gripe is that two units plus the cable is a bit more to pack than I expected for a weekend away. Still bring it though.
Bought it for my daughter, kept one
Got it for my daughter, she’s due in March, and kept one for myself. I’ve had restless legs about fifteen years. Set comes with two so we’ve got one each and we’re both sleeping.

Straight answers
Frequently asked
Will it stop on its own once the baby is here?
For plenty of women it fades within days of delivery. For plenty of others it does not — a large part of what drives it is iron demand, and that does not end at the birth: you lose blood delivering and then feed a newborn on top of it. Around a third of our customers were never pregnant at all. It is two devices with a one-year warranty, not something you throw away in eight weeks.
Is it safe while I am pregnant?
KAIRA Still is worn over the skin on the calf — external and mechanical, with nothing ingested or absorbed. That said, we are a wellness device and not your clinician: show it to your OB or midwife before you use it.
How fast will I notice a difference?
Most women feel the urge soften during the first 15-minute session. Give yourself three nights to find your intensity — level 3 is where most people land.
Can I use it every night?
Yes. There is no tolerance effect and nothing accumulates in your system. Most customers run one 15-minute session as they get into bed, and a second if they wake in the night.
Why two devices instead of one?
Because restless legs does not pick a side. Most nights it is both calves, and swapping one device between legs means chasing the sensation instead of settling it.
What if the strap wears out?
Two spare straps ship in every box, free. They are washable and replaceable.
When will it arrive?
Free US shipping on every set. Tracked delivery takes 5–7 business days, and the tracking number is emailed as soon as the parcel leaves.
