Sound familiar?

Most people find us after their third heating pad.

A man in his sixties walking down the stairs at home, one hand on the rail
A normal day with a stiff kneeTuesday

The first ten steps are the worst. The knee has to warm up before it agrees to work.

Going up is fine. Coming down, it's the rail and one step at a time.

Third heating pad this year. Warm on one patch, slid off by midnight, and you're rubbing the knee again.

Why it is not another heating pad

A pad warms one patch and slides off. Kneeby closes around the knee.

Three things in one 10-minute session, so it fits into an evening on the sofa instead of an appointment book.

01 · Heat

Warmth that gets into the joint

The shell closes around the kneecap, so heat reaches it from the front and both sides instead of sitting on the skin. Warm in about 2 minutes, three levels.

02 · Light

The clinic's red light, at home

20 red and near-infrared LEDs in a ring around the joint. The same type of red light physio clinics use, paid per visit. Yours every night.

03 · Vibration

A gentle buzz, not a knead

Quiet enough for bed. A soft hum that helps a knee that sat all day relax, while the heat and light do the work.

How to use

Three buttons, ten minutes, nothing to learn.

Wrap it on
01

Sit back

It switches itself off at 10 minutes. Fall asleep with it on if you like. Next morning, the strap goes on for the stairs.

Why Kneeby

A heating pad warms one patch and slides off. We put the three things a stiff knee asks for into one wrap that stays on, and built a full kit around it.

  • Ten minutes, then it switches itself offNo app, no cord, no timer to set. Put it on with the TV and forget about it.

  • 30 days to try it at homeIf the stairs aren't easier, send it back for a full refund. The gifts stay with you.

The questions people ask before they order

I've tried heating pads and massagers before.

That is why this is not a pad. A pad warms one patch and slides off. Kneeby closes around the kneecap, warms it from three sides and adds the red light pads don't have.

Will it fit my knee?

One size with an adjustable strap that fits most adult knees, slim or large. Not sure? Send us your knee circumference before you order and we'll tell you.

How warm does it get?

Three heat levels. Level 1 is a gentle warmth, level 3 feels like a hot-water bottle that stays put. It is warm, never burning, and it is warm in about 2 minutes.

Is red light real or a gimmick?

Physio clinics use red and near-infrared light and charge for it per visit. Kneeby puts 20 LEDs of the same type in a ring around the joint. We don't promise what it will do for your knee. You get 30 days to find out, and if it does nothing, you pay nothing.

Is it a deep massage?

No. The vibration is a gentle buzz, not a kneading massage. The heat and the red light do the main work, the vibration keeps it relaxing.

Is it loud?

The vibration makes a soft hum. If you watch TV or read in bed, turn vibration off. Heat and light are silent.

Can I walk around with it on?

It is made for sitting or lying down, the shell doesn't bend with the knee. For walks and stairs you wear the Stair Strap from the kit.

Are 10 minutes enough?

Most people do one session in the evening. If you want more, press the button again for a second round.

Is it hard to use?

Three buttons on the top: heat, light, vibration. No app, no remote, no pairing. It charges with any USB-C phone charger, about 8 sessions per charge.

Can I use it on both knees at once?

Yes, that is what the Complete Kit is for. Two wraps, both on at the same time, both done in the same 10 minutes.

Is it safe for me?

Gentle heat, low-power red light and vibration. After knee surgery or replacement, with a metal implant or pacemaker, with diabetes or poor feeling in the legs, or in pregnancy, ask your doctor first. Not for children.

I'm buying it as a gift. Is that OK?

Yes. The 30 days start when it arrives, so they can try it at their own pace.

What if it stops working?

Every Kneeby has a 2-year warranty. Email us a short video and we send a replacement.

Shipping and returns?

Free tracked shipping on every kit, delivered in 5 to 11 business days. The device or add-ons on their own ship for $4.95, free from $119. 30 days to return it for a full refund, and the gifts are yours to keep.
