Best extra large heating pads

Top pick: Garvee Massaging Heating Pad for Neck and Shoulders and Back — a 24" x 35" pad that drapes over the shoulders and down the back, with 4 massage motors and 3 heat levels, so you get heat plus kneading in one go. It's the best-rated of the big pads here.

Who the others suit:

• Thermophore MaxHEAT — the choice for deep, moist heat: it runs up to 165°F and shuts itself off after 25 minutes.
• TCVOR Extra Large (24" x 33") — a simple, well-rated wrap for neck, shoulders and back if you don't want massage.
• Beurer Weighted XL — the 3.4 lb weight and glass-bead fill press the heat against a sore back; it heats in about 30 seconds.
• Pursonic Extra Large — a light, plush pad for general back and shoulder use at the lowest cost.
• XL Electric Heating Pad (40" x 20") — the longest coverage, with 8 settings, for lying across the whole back.

Check each listing for auto shut-off if you tend to fall asleep under it — several of these don't state one.
