Relyon single bed - converts to kingsize (Oldfield Park)

We’ve changed the loft room from a spare bedroom to an office, which means we no longer need this helpfully versatile Relyon bed. In the format shown in the photos, it’s a regular single bed. However, there’s a second mattress and bed slotted in underneath, which slides out, zips to the first mattress and makes it a kingsize bed. We just don’t have the space to show you this but as you can see, I’ve pulled out the second mattress a little.
As a bonus to this modularity, no single piece of it weighs much, so two people can easily carry and move each piece.
