If your knee pain is caused by arthritis, inflammation, stiffness, poor circulation, or general aging, then yes—ComfrtKnee is designed specifically for you. It works by targeting the root causes: increasing blood flow with infrared heat, relaxing muscles with vibration, and reducing swelling with compression. Hundreds of users with conditions ranging from osteoarthritis to old sports injuries have found relief. That said, if you have severe structural damage or need surgery, this is a complementary therapy—not a replacement. But for the vast majority of chronic knee pain sufferers, it provides significant, noticeable relief.

Great question. Regular heating pads only provide surface-level warmth. ComfrtKnee uses infrared heat therapy—the same technology NASA developed for astronauts—which penetrates deep into your joint to increase blood flow at the cellular level. Plus, it combines heat with vibration massage and compression, giving you a 3-in-1 treatment that simple heating pads can't match. It's also cordless and hands-free, so you can use it while watching TV, reading, or even doing light chores.

Most users feel immediate relief during their first session—the warmth and massage feel amazing right away. For lasting results, we recommend using it for 15 minutes daily. Many people report significant improvement within 2-4 weeks of consistent use. One customer said his pain went from 8/10 to 2/10 after just 3 weeks. Your results may vary, but the key is consistency.

Yes! ComfrtKnee features adjustable Velcro straps that fit leg circumferences from 12" to 24". Whether you have larger legs, swelling, or a smaller frame, it adjusts comfortably to your size. The interior is cushioned and ergonomic so it won't pinch or squeeze uncomfortably.

The rechargeable battery provides 3-4 sessions (45-60 minutes total) per charge. It charges fully in about 2 hours using the included USB cable. Most people charge it overnight and use it throughout the week without needing to recharge daily.

Yes! While it's designed for knees, many customers also use it on shoulders, elbows, calves, and thighs. The adjustable straps make it versatile for multiple pain points.
