No. An Alaskan king is 108 × 108, much wider and 10″ longer.
Check the full 98-inch length against foot-of-bed furniture, doors and the delivery path. A mattress that fits the room still needs a foundation designed for that exact footprint.

6 of the 9 Texas king mattresses we list can be returned under the seller’s trial. Made-to-order mattresses often can’t. Each one’s return terms are in its details.
Mostly online from the brands on this page, which ship to most US addresses. Local mattress factories can build one; stores rarely keep this size on the floor.
Prices change often, so we link to each seller instead of listing them. Odd sizes are often priced at or above the nearest standard size, and made-to-order ones usually cost more.
Usually not. Owner feedback is about the mattress model, often in a more common size. Each summary says whether it’s about this exact model, and links to the source.
