Light and warmth for a neck and shoulders that never quite relax.
Some days a stiff neck just wants warmth. Other days your shoulders need something that goes deeper than a warm pad. The 7HW MantleFlex wraps your neck and shoulders in red and near-infrared light, and the near-infrared light creates a gentle warmth you can feel, with no heating wires inside. Drape it over your shoulders, choose your level and timer, then settle into the sofa or get back to your screen while it works.
Who reaches for the MantleFlex
If you reach for a heat pad every time your neck stiffens up, and you want something that works below the surface too, this is where to start.
"My neck is stiff before lunch."
Desk & laptop workers
Wrap it over your shoulders at your desk and let the light and warmth work while you answer emails.
"Warmth is the only thing that loosens me up."
Warmth seekers
The near-infrared light creates a soothing warmth up to 114.2°F, with no heating wires against your skin.
"My shoulders are tight after every workout."
Gym & yoga regulars
A warm, relaxing session after training, with a 40Hz pulse mode for your recovery routine.
"By evening it's my lower back that aches."
Back & tummy comfort
Move the pad from your shoulders to your lower back, waist or tummy whenever that's where you need it.
Two kinds of comfort, one simple wrap
Light that works at the surface and beneath it, with a warmth you can feel
Red light works at the skin's surface, while invisible near-infrared light reaches the tissue beneath. That near-infrared light is also what makes the wrap feel pleasantly warm, so you get the comfort of a heat pad without any heating wires inside.
Keep it gentle on good days, turn it up on stiff ones
Some evenings you want a soft, cosy warmth. After a long week you want more. Five power levels raise the warmth and the light output together, so you can match each session to how your neck and shoulders feel today.
Steady light for everyday, pulsed light to wind down or recover
Choose constant light for a daily relaxation session, a slow 10Hz pulse when you want to wind down at the end of the day, or a 40Hz pulse as part of your post-workout recovery. Switch with one button on the remote.
Pick a time, then forget about it
Set a quick 10-minute session before a call or a long 90-minute wind-down with a film. The wrap switches itself off when the time is up, so you can relax without watching the clock.
Neck and shoulders today, lower back or tummy tomorrow
The contoured shape fits around your neck and over both shoulders, and the front panel crosses over to hold it in place. Lay it flat and it works just as well on your upper back, lower back, waist or tummy, so one wrap covers the spots that ache most often.
Plug in and relax for as long as you like
The MantleFlex runs from the mains, so there's no battery to charge first and no power fading halfway through a long session. Keep it by your favourite chair or your desk and it's ready whenever you are, at full output, every time.
A routine that rewards consistency
Warmth feels good straight away. The light works best as a regular habit. Here's how most routines unfold.
The warmth starts to soften tight muscles within minutes, and most people find it an easy way to unwind.
Sessions become part of your day: at your desk, after a workout, or on the sofa in the evening. Regular sessions matter more than long ones.
Consistent users often notice their neck, shoulders and back feel looser and more comfortable day to day. Individual results vary.
Five steps, about 20 minutes
- Plug inConnect the remote to the wrap and plug the adapter into the wall.
- PlaceDrape it over your neck and shoulders and cross the front panel to secure it, or lay it flat on your back, waist or tummy.
- ChoosePress M to pick a light mode and use LED +/– to set your level. Start low.
- Set timeUse TIME +/– to choose 10–90 minutes. About 20 minutes is a good everyday session.
- RelaxSit back, read or work. The wrap switches off automatically when the timer ends.

Gentle by design
Warm, never scalding
No heating wires. The light warms the surface to a maximum of 114.2°F on the top level, with an automatic timer. Start low, and don't fall asleep with it on. No UV.
Easy to look after
Unplug before cleaning. Spot-clean the velvet with a soft, slightly damp cloth and let it dry fully. Do not machine-wash or submerge.
Check before use
Don't look directly into the LEDs. If you are pregnant, light-sensitive, diabetic or have reduced skin sensation, an implanted medical device or a skin condition, consult your doctor first.

Questions before you buy
The MantleFlex has no heating wires. The warmth comes from its near-infrared light, from 98.8°F on level P1 up to 114.2°F on P5. Most people start on P1 or P2 and turn it up once they're used to it.
Yes. It's shaped for the neck and shoulders, but you can lay it flat on your upper back, lower back, waist or tummy. Many people move it around depending on where they feel tight that day.
Constant mode is a good everyday choice. Try 10Hz pulse when you want to wind down in the evening, and 40Hz pulse as part of your routine after exercise. You can switch modes at any time with the M button.
About 20 minutes is a good everyday session. The timer goes from 10 to 90 minutes, and the wrap switches off automatically when the time is up.
No. It runs from the mains through the included adapter, so there's no battery to charge and it delivers full power for the whole session. It's ideal for your desk, sofa or favourite chair.
Choose the plug for the country where you'll use it: US, UK, EU or AU. The adapter works on 100–240V.
That's normal. Each LED has a 660nm red chip, which you can see, and an 850nm near-infrared chip, which is invisible to the human eye. When you see the red glow, the near-infrared light is working alongside it.
We don't recommend it. Because the light makes the wrap warm, use it while you're awake, and let the auto-off timer end each session.
You'll still feel the warmth through a thin top, but light works best on bare skin. Remove thick layers before a session.
If you are pregnant, light-sensitive, diabetic or have reduced skin sensation, an implanted medical device or a skin condition in the area, consult your doctor before use.
