South Bay 12" ActiveAlign Reactive Copper Zoned Mattress - Medium

Split King ordering (two Twin XL mattresses)

For a split Eastern King (regular King), select the Twin Long / Twin XL size and order quantity 2. You will receive two individual Twin XL mattresses, one for each side. The older “King Split” choice is temporarily unavailable to prevent confusion over its bundled price and contents. A standard King size is one full-width mattress; a split-head mattress separates only at the head and is not a full split.

Our advertised selling prices include standard carrier shipping within the contiguous United States.

The 12-inch ActiveAlign Reactive Copper Zoned mattress features copper-gel memory foam, responsive foam, targeted comfort zones and a breathable Air Grid base for an adaptable medium feel. Reinforced edge support improves the usable sleep surface.

Zip-off washable cooling cover; compatible with an adjustable base, sold separately. Manufacturer's 10-year limited warranty.
