Thermophore MaxHEAT Moist Heating Pad – Large 14" x 27" for Back, Shoulders & Legs – Deep Heat Therapy Pad (Model 155)
Thermophore MaxHEAT Moist Heating Pad — Large 14" × 27" (Model 155)
Our #1 best-selling moist heating pad. Weighted to contour your body, reaches up to 165°F, produces deep moist heat automatically from humidity in the air — no water needed. Three heat settings, 25-minute auto shutoff, washable fleece cover, 10-foot cord. Drug-free pain relief trusted by doctors since 1931.
It's slightly weighted, it has this humidity feature which seems to really help the heat penetrate, and it actually gets hot. I've now also bought this as a gift for a friend too.
Our Take: The MaxHEAT 155 is the Thermophore that most people buy — and for good reason. At 14" × 27", it covers your entire back, wraps around a hip, or drapes across both shoulders. The approximate 4 lb weight molds to your body's curves, maintains full surface contact, and stays put without you holding it. The fleece cover draws moisture from the air and the pad's intense heat converts it to therapeutic steam — no water, no damp towels. Three heat settings via a one-touch hand switch plus a 25-minute auto shutoff. At up to 165°F, it runs dramatically hotter than many generic pads. If you want USA assembly, the Liberty 155 is the same pad assembled in Indiana.
Why You'd Choose the MaxHEAT 155
- Many generic drugstore pads max out around 120°F to 140°F. The MaxHEAT 155 reaches up to 165°F on the High setting — the intensity needed for deep, therapeutic moist heat.
- At roughly 4 pounds, the pad is noticeably heavier than generic pads. That weight helps it conform to curves and joints, maintaining fuller surface contact for more consistent heat delivery.
- The fleece cover absorbs humidity from the air. Combined with the pad's intense heat, this creates deep, penetrating moist heat therapy without adding water or damp towels.
- The one-touch Constant-Comfort hand switch gives you three temperature levels. Start on Low, move to Medium for stronger relief, or use High for maximum therapeutic intensity.
- The large size covers the full back from shoulders to lower back, wraps around a hip or thigh, or drapes across both shoulders simultaneously.
- The auto shutoff aligns with commonly recommended therapy intervals of 15 to 30 minutes. Also reduces risk of overheating if you fall asleep with the pad on.
- Moist heat therapy can help ease arthritis, back pain, muscle spasms, fibromyalgia, and sports soreness by increasing blood flow and helping muscles relax.
- The MaxHEAT 155 qualifies for HSA and FSA purchases. Also approved for Medicare reimbursement when prescribed for arthritis pain management.

Frequently Asked Questions
What is the difference between the MaxHEAT 155, Liberty 155, and Classic 055?
All three are 14 × 27 inch large pads with the same weighted, moist heat design. The MaxHEAT 155 has a 3-setting switch and 25-minute auto shutoff, assembled in China. The Liberty 155 is identical but assembled in the USA. The Classic 055 uses a press-and-hold switch — heats only while you hold the button. All reach the same 165°F maximum.
How does the Thermophore produce moist heat without adding water?
The fleece cover absorbs moisture from the humidity in the surrounding air. When the pad heats up, it activates that moisture into therapeutic steam. No water, spray bottles, or damp towels needed. The cover produces moist heat for 20–30 minutes, then set it aside to reabsorb moisture.
Why does the pad shut off after 25 minutes?
The 25-minute auto shutoff is a safety feature. Thermophore pads reach higher temperatures than generic brands, so limiting exposure to 25 minutes follows recommended therapy intervals and prevents burns if you fall asleep with the pad on.
What temperature does the MaxHEAT 155 reach?
Up to 165°F on the High setting, via three settings: Low, Medium, and High. Most generic drugstore pads max out around 120–140°F.
Is it HSA or FSA eligible?
Yes. The MaxHEAT 155 is HSA and FSA eligible. Also approved for Medicare reimbursement when prescribed for arthritis pain management.
Is the cover washable?
Yes. The soft fleece flannel cover is removable and machine washable. Clean regularly for optimal moist heat performance.
Can I lie on this heating pad?
No. Place it on top of the body area only. Lying on a heating pad can trap heat against the skin and increase the risk of burns.

Our Take: The MaxHEAT 155 is the Thermophore that most people buy — and for good reason. At 14" × 27", it covers your entire back, wraps around a hip, or drapes across both shoulders simultaneously.

Frequently Asked Questions
What is the difference between the MaxHEAT 155, Liberty 155, and Classic 055?
All three are 14 × 27 inch large pads with the same weighted, moist heat design. The MaxHEAT 155 has a 3-setting switch and 25-minute auto shutoff, assembled in China. The Liberty 155 is identical but assembled in the USA. The Classic 055 uses a press-and-hold switch — heats only while you hold the button. All reach the same 165°F maximum.
How does the Thermophore produce moist heat without adding water?
The fleece cover absorbs moisture from the humidity in the surrounding air. When the pad heats up, it activates that moisture into therapeutic steam that penetrates deeper than dry heat. No water, spray bottles, or damp towels needed. The cover produces moist heat for 20–30 minutes, then set aside to reabsorb moisture from the air.
Why does the pad shut off after 25 minutes?
The 25-minute auto shutoff is a safety feature. Thermophore pads reach higher temperatures than generic brands, so limiting exposure to 25 minutes follows recommended therapy intervals and prevents burns if you fall asleep with the pad on.
What temperature does the MaxHEAT 155 reach?
Up to 165°F on the High setting, via three settings: Low, Medium, and High. Most generic drugstore pads max out around 120–140°F.
Is the MaxHEAT 155 HSA or FSA eligible?
Yes. HSA and FSA eligible. Also approved for Medicare reimbursement when prescribed for arthritis pain management. Check with your insurance company to verify coverage.
Is the cover washable?
Yes. The soft fleece flannel cover is removable and machine washable. Keep it clean for optimal moist heat performance — the fleece fibers are what absorb humidity to create automatic moist heat.
Can I lie on this heating pad?
No. Place it on top of the body area only. Lying on a heating pad traps heat against the skin and increases the risk of burns. The weighted design keeps the pad in place without lying on it.
