Hyron's a trundle bed with two mattresses – extend it out when guests are around, then change it back to a single when they've left.
You can use Hyron as a double bed, or two singles, when extended. Two side-by-side single mattresses mean you've got options, depending on how many sets of bedding you make it up with.
The second mattress, when not in use, can be stored neatly within the base of the upholstered bed frame.
