Far Infrared Heating for Deeper Warmth: This heating pad emits far-infrared waves that are easily absorbed by the body, providing deeper, soothing warmth from the inside out. It also helps ease back, period and daily discomfort—ideal for post-workout relaxation.
Tourmaline and Jade Stone Heating: Unlike regular pads that only warm the surface, this XXL FIR pad uses natural jade and tourmaline, which gradually absorb and store heat, taking about 20 minutes to reach full warmth. Once heated, they express even, steady heat that delivers deeper warmth to ease discomfort and provide long-lasting comfort.
Temp & Timer Control Settings: This FIR heating pad offers 6 heat levels and 8 timer settings, letting you adjust both warmth and duration for personalized comfort. Use it for quick comfort or longer sessions to ease discomfort. With built-in auto-off to prevent overheating, it provides safer, more flexible, and dependable comfort than ordinary pads.
Extra Large Full Body Coverage: Measuring 17″×33″, this extra-large heating pad provides wide, even warmth across the back, abdomen, and legs. It’s a practical solution for full-body comfort, especially useful during cold days or whenever you need long-lasting relaxation over larger areas.
FSA/HSA Eligible Wellness Gift: This heating pad for back comfort is FSA/HSA eligible and makes a thoughtful gift for men or women who seek natural relaxation from back and period discomfort. It combines comfort, safety, and effectiveness—an excellent choice for self-care or as a practical wellness gift.
Usage Tips: Use the heating pad for the lower back over light clothing or a towel to protect your skin—never directly on bare skin. Start with the lowest heat setting and check your skin regularly during longer sessions. If the pad stops heating, unplug and firmly reconnect the coupler to restore function. Suitable for anyone seeking a safe, natural way to ease back discomfort and daily discomfort.

This isn’t your typical heating pad.
I have fibromyalgia and scoliosis. This helps with the muscle spasms. It’s not too hot to where it would cause issues. I use this at work and it fits my work chair perfectly. The timer is up to 90 minutes by 10 minutes increments. It is a little pricey, but well worth the price. I used HSA/FSA on this item. Very sturdy. Overall, the quality is amazing. I love this product.

What’s causing the error msgs
Displeased with this product, had the unit for 2 months and now the unit doesn’t turn on with an “FF: error code preventing me from being able to use the unit. So I’ve been using my 25 dollar unit from walmart and it get’s hot, consistent, and I don’t have to worry about the mat like bending into a crinkle that will not straighten out..

Great heat
LOVE this. It’s big enough to cover my entire back and it stays hot for a long time even when it’s off. I was worried that it would be uncomfortable to lay on but it’s really not. I don’t notice that I’m laying on stones

Very nice, just not hot enough for me
If you’ve never tried FIR (far-infrared) heat therapy, it can be great. This pad is well made and easy to use, but it just didn’t get hot enough for my needs.I deal with spinal/thoracic pain and used to have a UTK pad that worked really well before it died. I bought this hoping it would be a cheaper replacement, but even after running on the highest setting for 30+ minutes, the heat never felt strong enough to penetrate through clothing and provide deep relief.Also worth noting: the product photo shows someone lying on the pad, but the instructions say you’re not supposed to lie on it. Aside from in my office chair, this is how I normally use heating pads, so that was a downside for me.Overall, the quality and design are good, and it fits nicely on a chair if you want heat while sitting. It just doesn’t get hot enough for my particular pain needs.

Good for pain relief and tingle
I think is deceiving to advertise with a woman laying on the mat when the instructions are very clear about not laying on the mat. No bueno!I place it on a chair and I enjoy the heat from the stones. It takes 15-20 minutes to heat but once it does keep nice and warm for a while.It does help with pain relief and tingle of the muscle even though I can’t lay on it I’m pleased with how it worksI wish the cord was longer

Great heating pad!!!
This heats up quite well and feels very nice. I usually lay on it even though it says not to. But I still really enjoy it.
