Strap it on. Press start. Sit back.

Strap it on
Place it over the knee and close the straps.
Pick your level
Warmth, massage or both. Start gentle.
Sit back
15 minutes. Read, watch TV, do nothing.
Stand up
Your knee feels warm and loose.
Stairs down worse than up? There's a reason.
Stiff for the first steps after the couch. Careful on the way downstairs. Slower to get going in the morning. It's usually not just age.
Your knee has almost no muscle of its own. It relies on movement to pump warm blood through the joint. Less movement, less blood flow. Cold, stiff knees make you move even less. That's the loop.
You already know warmth helps. A hot bath, a heating pad: the relief is real. It just never reaches deep enough, and it's gone by morning.
knivio holds deep, even warmth right on the joint and adds kneading massage and red light. Like a hot compress and a pair of skilled hands, every evening, at the push of a button.
And for the hours in between: wear the included compression sleeves. Gentle support during the day, deep warmth in the evening. That's the full routine, and the sleeves come free with every order.
- Less movement = less blood flow around the knee
- Cold, stiff knees make you move even less
- Warmth, kneading and red light break the loop from the outside
- Every evening, so the stiffness doesn't settle back in

How people describe their knees before and after one session.
For the moments your knees dread
Before you join
What's in the box?
1 knivio knee massager, 2 compression knee sleeves (your free gift), a charging cable and the manual. The 2-device set comes with 4 sleeves.
Which sleeve size should I pick?
The sleeves are stretchy and come in S, M and L. If you're usually M in trousers, pick M here. Between sizes? Take the larger one.
What does it feel like?
Warm, with a kneading squeeze and gentle vibration around the knee. You set the strength yourself. Start on the lowest level.
Is this just another gadget?
Fair question. knivio doesn't promise miracles. It does one thing well: deep warmth and kneading massage, every evening. You feel the warmth in the first minute. If your knees don't feel looser after a few weeks, send it back within 60 days for a full refund.
When will I notice something?
You feel the warmth right away. Most people say the knee feels looser right after the first 15 minutes.
How often should I use it?
15 minutes a day is plenty. Most people make it an evening habit. Wear the compression sleeves during the day whenever your knees want a little support.
Is it safe for me?
It's made for everyday home use. If you have a pacemaker, are pregnant, have an acute injury or a diagnosed joint condition, ask your doctor first.
Will it fit my knee?
The straps are adjustable and close around slim and strong legs alike.
Is it complicated to use?
No. A simple panel with a few buttons, no app needed. If you can use a TV remote, you can use knivio.
When does it ship?
The first batch is being prepared now. Join the waitlist and we'll email you the moment it's ready, with your intro price locked in.
What if it's not for me?
You'll have 60 days from delivery. If it doesn't win you over, send it back for a full refund. The sleeves are yours to keep either way.

Placeholder review. Target wording from real 5-star language: 'first time in years I slept through the night', 'started enjoying my weekends again', 'reduced the ibuprofen'.
Placeholder review. Plain and specific, the way a real person talks. No marketing words.
Placeholder review. A 4-star voice with one small honest nitpick reads more credible than all 5s.
