Comfytemp Extra Large Heating Pad 17" x 33" review

The Comfytemp 17" x 33" pad is the value pick for anyone who wants to cover a whole back, or wrap a knee, for the least money. Comfytemp sells it for $31.99 on sale, down from $39.99, with free shipping. That buys the largest flat pad on this list, a flannel cover that comes off the cord for machine washing, 3 heat levels and a 2-hour auto power off with overheat protection. Comfytemp lists 30-day free returns, a 365-day warranty and HSA/FSA eligibility. The product page does not publish the temperature of each level, so you cannot compare its heat directly with Pure Enrichment's 105°F to 140°F range or Thermophore's 165°F. Comfytemp also tells buyers not to sit or lie on the pad or fold it, which rules it out for people who want to lie back on their heat. For draping over the back, shoulders or legs while sitting up, it is the most coverage per dollar we found.
