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
- Reaches 165°F — most drugstore heating pads max out at 120–140°F. The extra heat is the key to genuine therapeutic relief, not just surface warmth.
- The weight is a key differentiator. It molds to body contours, maintains full surface contact across curved areas like the lower back and hips, and stays in place without you holding it.
- The fleece cover absorbs humidity from the air between sessions. When the pad heats up, it activates that moisture into therapeutic steam. No spray bottles, no wet towels — just plug in and use.
- One-touch Constant-Comfort hand switch cycles through Low, Medium, and High. Hold at your chosen setting — no holding required once you've selected your level.
- Large enough to cover the entire lower back from hips to mid-back, wrap around a hip or thigh, or drape across both shoulders simultaneously. The most versatile size in the lineup.
- Built-in 25-minute automatic shutoff ends every session safely — no manual monitoring required. Ideal for use while resting, reading, or relaxing without worrying about falling asleep with it on.
- Moist heat increases blood flow, relaxes muscle spasms, and reduces joint stiffness — without NSAIDs, opioids, or other medications. A core reason physical therapists and physicians recommend Thermophore.
- Qualifies for purchase with HSA and FSA funds. 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?
The MaxHEAT 155 and Liberty 155 are the same pad — three heat settings, one-touch switch, up to 165°F — the only difference is the Liberty 155 is assembled in the USA and the MaxHEAT 155 is assembled in China. The Classic 055 uses a press-and-hold switch: it heats only while you hold the button, then cools when released.
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 into muscles and joints than dry heat. No water, spray bottles, or damp towels needed. The cover produces moist heat for 20–30 minutes per session.
Why does the pad shut off after 25 minutes?
The 25-minute auto shutoff is a built-in safety feature — it ends every session automatically so you never have to worry about leaving it on. Most physical therapists recommend 20–30 minute heat therapy sessions, so the shutoff aligns with best practices. For longer sessions, consider the Digital 655 which allows up to 60 minutes.
What temperature does the MaxHEAT 155 reach?
Up to 165°F on the High setting. Most generic drugstore heating pads max out at 120–140°F. The extra heat is what drives the genuine therapeutic benefit — it's hot enough to produce therapeutic steam from the fleece cover.
Is it HSA or FSA eligible?
Yes. The MaxHEAT 155 is eligible for purchase with HSA and FSA funds. It is also approved for Medicare reimbursement when prescribed by a physician for arthritis pain management.
Is the cover washable?
Yes. The fleece flannel cover is removable and machine washable. For best results, hand wash in cool water with mild detergent and drip dry. Allow the cover to fully dry and reabsorb ambient moisture from the air before using it again. Do not use fabric softener — it can reduce the fleece's moisture-absorbing properties.
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 significantly increases the risk of burns — even at lower settings. The approximately 4 lb weighted design keeps the pad in place and maintains full contact without the need to lie on it.

Frequently Asked Questions
What is the difference between the MaxHEAT 155, Liberty 155, and Classic 055?
The MaxHEAT 155 and Liberty 155 are the same pad — three heat settings, one-touch switch, up to 165°F. The only difference is assembly location: Liberty 155 is assembled in the USA, MaxHEAT 155 is assembled in China. The Classic 055 uses a press-and-hold switch: it heats only while you hold the button and cools when you release it.
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 into muscles and joints than dry heat. No water, spray bottles, or damp towels needed. The cover produces moist heat for 20–30 minutes per session, then set aside to reabsorb moisture.
Why does the pad shut off after 25 minutes?
The 25-minute auto shutoff is a built-in safety feature — it ends every session automatically so you never have to worry about leaving it on. Most physical therapists recommend 20–30 minute heat therapy sessions, so the shutoff aligns with best practices. For longer sessions, the Digital 655 allows up to 60 minutes.
What temperature does the MaxHEAT 155 reach?
Up to 165°F on the High setting. Most generic drugstore heating pads max out at 120–140°F. The extra heat is what drives genuine therapeutic benefit — it's hot enough to produce therapeutic steam from the fleece cover.
Is the MaxHEAT 155 HSA or FSA eligible?
Yes. The MaxHEAT 155 is eligible for purchase with HSA and FSA funds. It is also approved for Medicare reimbursement when prescribed by a physician for arthritis pain management.
Is the cover washable?
Yes. The fleece flannel cover is removable and machine washable. For best results, hand wash in cool water with mild detergent and drip dry. Allow the cover to fully dry and reabsorb ambient moisture from the air before using again. Do not use fabric softener — it can reduce the fleece's moisture-absorbing properties.
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 significantly increases the risk of burns — even at lower settings. The approximately 4 lb weighted design keeps the pad in place and maintains full contact without the need to lie on it.
