Duralink Trundle Bed, Exclusively by Humble Abode. Four ways to use for flexible accommodations. Leave the trundle rolled under for a space saving single twin bed. Roll the trundle out but leave it in the down position as a drawer trundle (kids and sleep-overs). Pop up the trundle bed next to the high rise bed frame to create a king size bed for couples. Roll the trundle against the opposite wall from the high rise frame or to a separate room for two separate twin beds.
