What to know before buying

Listing details to confirm

The listing is inconsistent about pocket depth: it gives 17 inches in the feature text but the display dimensions read 80 x 78 x 17 inches, which does not clearly distinguish the pad's dimensions from pocket depth. The title gives 78"x80". Also, the nominal feature description mentions a quilted cotton cover and protection claims, while the explicit included-components list names only the pad, one controller and one manual. Dual-control claims for King sizing specify two controllers, but the package list specifies one, so controller quantity is unconfirmed. Confirm the selected listing and fit details before purchase. For washing, unplug the controller and follow the listed restrictions: do not dry clean, bleach or iron.

Frequently asked questions

Does this King pad have separate controls for each side?

The feature description says King sizes have dual controllers so two users can adjust their sides independently. However, the explicit package list states one temperature controller, so confirm the selected listing's controller quantity.

What mattress depth does it fit?

The listing says the 17-inch deep elastic pocket fits mattresses up to 17 inches thick. Its display dimensions also include 17 inches, so check the listed fit details for the selected version.

Can the pad be machine washed?

Machine washing is listed. The instructions say to unplug the power cord from the controller first and not to dry clean, bleach or iron.

What do customer comments say about comfort and heat?

Feedback describes comfort on cold nights and says the pad can stay in place, but reports are mixed on softness, controls and heat distribution. Some customers say wires are noticeable and feet take longer to warm.
