Great For My Sciatica Pain

"I've had sciatica for years and finding a good support belt is tough. Most of them are too rigid and don't offer flexibility. But this one is the best combination of support + flexibility I've found. Plus I love that I can tighten it with the straps if I need to."

My Daughter Uses It At Work

"I bought this item for my daughter who was having back pain due to lifting heavy produce boxes at the store she works at. She loves the way it decreases the stress on her back and that it’s comfortable to wear under her uniform. She recommended it to a fellow coworker and now almost everyone at the store has one!"

Husband LOVES It!

"I've bought several braces that he hasn't liked but he loves this. It gives him support without being too stiff. Plus he loves that it's slim and he can wear it under t-shirts. He says this is comfortable and gives enough support to make him feel secure and help to not put too much strain on his lower back."

Introducing The NEW ComfortFlex™ Lumbar Support Belt

Feel Back Pain Melt Away With Targeted Deep Heat Combined With Firm And Flexible Support

  • The ComfortFlex™ was designed with triple support that combines a molded spinal plate with 2 side bolsters to secure the lower back in a safe and natural position. This protects you from injury, while gently stretching and releasing pressure from the vertebrae (spinal discs), for relief in minutes.
  • The ComfortFlex™ comes with 3 different inserts so you can customize your experience. Choose from breathable, warm, or self-heating support.
  • The breakthrough self-heating pad uses magnets and cutting-edge materials to redirect body heat to the lower back - keeping muscles warm, melting pain away, and improving blood flow for faster recovery.
  • With compression straps that attach with velcro in the front so you don’t have to twist and turn trying to hook them in the back like other support belts. You’ll be able to easily tighten or loosen the support straps for the exact amount of support you need.

Frequently Asked Questions

Will This Help With My Posture?

It can, over time. It forces you to keep your posture upright instead of having a lazy slouch. It will take some getting used to at first, but over time you'll notice your posture improves even when not wearing the ComfortFlex.

Can you wear this in the gym?

You could, but it won't be a comfortable experience. Back exercises are great for improving your strength, and the ComfortFlex is great to wear when you're not working out so your muscles are supported. If you've got back pain then speak to your physician first before performing exercise.

What if it doesn't fit me?

The ComfortFlex comes with adjustable straps that should make it easy to fit for any waist size. But, if the ComfortFlex just doesn't feel comfortable for you, you can always contact us directly for a full, no questions asked refund within 90 days.

Will This Help With A Hunched Back?

The ComfortFlex can help with a hunched back. By pulling your shoulders back and straightening your spine and back, the brace assists your body to have a more natural posture.

Can it be worn under clothes?

Yes! The ComfortFlex is designed with ultra thin and breathable material so you can have it on no matter where you go and no one will notice.

Where can I buy this in person?

Currently we sell our product exclusively online.
