How to choose
Heat settings and auto-off
Heat settings decide how finely each sleeper can tune warmth. The Sunbeam has 12 heat settings, the SurChic has 10, and the SameBed has 9, so compare those counts against how much control you want at night. Auto-off times also differ: the Sunbeam shuts off after 12 hours, the SurChic after 10 hours, and the SameBed offers 2, 4, 6 or 10 hour timer choices. The Valthie offers auto shut-off from 1 to 12 hours. Match the setting count and the shut-off span to your sleep routine before weighing fabric or pocket depth.
Pocket depth and fit
A heated pad must stay in place on a king mattress, so pocket depth matters as much as heat. The Sunbeam fits mattresses up to 16 inches, the SurChic has a 21 inch deep pocket, the Valthie fits mattresses 8 to 21 inches thick, and the SameBed fits mattresses 8 to 21 inches. Measure your mattress depth first, then check it against the pocket figure for the pick you want. An elastic skirt helps the pad stay in place during sleep.
Wash care and cords
All five picks are machine washable, so the difference is in the details. Remove the controller before washing on the Valthie and SameBed, and follow the care instructions for drying. The Valthie adds a 6-foot power cord with a 12.8-foot controller cord for reach from bed, and its controller display turns off after 20 seconds.
