  • Nice after being out all day

  • Back on my feet after my ACL injury

    Ever since my ACL injury, my knee felt like it belonged to somebody else. I started using this after my evenings at home and within a week I was convinced the warmth was helping it heal. I never expected a little device to make me feel this hopeful again.

  • My arthritis pain practically disappeared

    I am 67 and have dealt with knee osteoarthritis for years. After only a few days using the warming massage, I went from dreading evenings to looking forward to my walks. The pain felt like it had almost vanished. Five stars from me.

  • I take it on trips

    A full afternoon of sightseeing usually leaves me ready for a break. A friend mentioned warming knee massagers, so I gave this one a try. That gentle warmth is exactly what I was looking for. I wish I had picked one up earlier.

Real reviews from people who use this device.

Why it works

Heat, massage and red light, each backed by research.

Arthritis specialists recommend heat and massage. Red light cut knee pain by more than half in a placebo-controlled trial. Your Knee Wrap brings all three to your knee at home.

What it means for you: 15 minutes of warmth and red light in your chair, morning and night. In the red light trial, pain dropped by more than half in 10 days. You have 90 nights to feel it for yourself.

Frequently Asked Questions

Still unsure? Write to us. A real person answers within 1 business day.

Will it help if I have arthritis or bone-on-bone knee pain?

Stillwell is designed for people dealing with stiff, aching knees, including discomfort associated with arthritis, osteoarthritis, and advanced joint wear. Its adjustable heat and vibration massage help soothe the surrounding muscles and ease everyday stiffness, making it a convenient addition to your knee-comfort routine.

Can it help with discomfort from ACL or meniscus injuries?

Muscle soreness and stiffness can remain frustrating during recovery from ACL or meniscus injuries. Stillwell's soothing warmth and gentle vibration massage can help relax surrounding muscles as part of a clinician-approved recovery routine.

How often should I use it?

Stillwell is designed for convenient 15-minute sessions. Enjoy a relaxing session in the morning, after physical activity, or before bed, following the device instructions and any guidance specific to your knee condition.

Does the relief last after I take it off?

The warming and massaging sensations are experienced during your session, and some people may continue feeling relaxed afterward. How long the comfort lasts depends on your individual knee condition, activity level, and daily routine.

Will it fit my knee?

Stillwell features two adjustable straps designed for knee circumferences between 10 and 22 inches. Simply secure the wrap around your knee for a comfortable fit.

Is it safe for me?

Stillwell features adjustable temperature settings and an automatic 15-minute shut-off. Begin with the lowest comfortable heat level. If you're pregnant, have reduced sensation, circulation issues, a pacemaker, recent injuries, or significant swelling, consult your healthcare professional before use.

How warm does it get?

Stillwell delivers soothing warmth in three adjustable levels, reaching up to 113°F. Select the temperature that feels most comfortable for your knee-care routine.

Is the massage noisy?

The heating system operates silently. When activated, the vibration massage produces a gentle hum, with Auto, Low, and High settings to customize your experience.

Can I use it after knee replacement surgery?

Stillwell's adjustable warmth and gentle massage can become part of a comfort routine once your surgeon approves their use. Your care team can help determine the appropriate stage of recovery and settings.

What does the red and near-infrared light do?

Stillwell includes a ring of red and near-infrared LEDs positioned over the kneecap. These wavelengths are being researched for their potential applications in knee discomfort management. The light feature operates independently, so you can personalize your sessions with light, heat, massage, or a combination of settings.

Can I try it risk-free?

Yes. Our Stillwell offer includes a 90-night trial and a 2-year warranty. Try the adjustable warmth, massage, and light features in your daily routine. If it's not the right fit, the offer includes a prepaid return label and refund upon carrier scan.

How does shipping work?

With this offer, a pair of Stillwell Knee Wraps ships free, while a single wrap ships for $4.90. Every order includes tracking, and the 90-night trial begins on delivery.

Buying it for Mom or Dad?

Stillwell's large illuminated buttons, adjustable warmth, and hands-free design make it easy to use. It's a thoughtful way to help someone you love add soothing knee comfort to their daily routine.
