Which is better for cold feet?

Both put extra coils near the foot of the bed and let you heat the foot zone separately. The Therma-Lock also lets you set a separate timer for the feet.

Is the Air-Lock worth choosing over the Therma-Lock?

If you need a Queen, yes. It has 270 ratings at 4.8 versus 22 at 4.6, and its 6-layer build hides the wires better. The Therma-Lock adds a per-zone timer and a Sherpa fleece top.

Do both have the same heat settings?

Yes. Both offer 9 levels from 84–129°F across 4 zones, with 1–12 hour auto shut-off and low EMF.

Both carry a 5-year warranty and dual overheat protection, so the warranty terms match. The Air-Lock's larger review base gives more evidence of long-term reliability.

Can two sleepers set different temperatures?

The Therma-Lock Twin has dual controls, so yes. The Air-Lock Queen uses one LCD multi-zone controller with separate body and foot zones.

The Therma-Lock was $84.00 as of November 1, 2026. No price was given for the Air-Lock, so check current store prices before buying.
