Current option offered under this mattress name. Official Kids collection markets a distinct slim 5-inch Twin mattress for trundle beds and guests. This is a human mattress, not an accessory.

Why these options share one page: They are sold under the same marketed mattress name. Firmness, height, and size choices stay together here, and any documented construction differences are explained beside the relevant option. A different marketed mattress name always receives its own page.
