Many private dwellings have a room set aside as a "guest bedroom".
This bedroom may be equipped with a variety of sleeping accomodation; single beds, double beds, bunk beds, or just floor space are commonly encountered.
Sometimes, for motives that are not readily understandable, guests may elect
to bring their children with them (Are their no cupboards under the stairs, no garden sheds ?).
When the guest room is already equipped with a double bed, this can prove inconvenient, as little floor space may remain for the children.
Assuming that sending the horrible little sods to sleep under the car is not an option, this usually involves trying to wedge in various folding beds, etc.
But for the establshment that boasts the latest BorgCo innovation in sleeping comfort, such concerns are a thing of the past. On first inspection, it is a basic, unadorned four-poster bed; but simply prsss the remote control, and the bed frame slowly and smoothly climbs up the four corner posts, like a mechanic's lifting ramp in a garage.
After a few seconds, the mattress reaches 1.5 metres above the floor, revealing a secondary frame into which a second matress (or matresses) is (or are) fitted
It remains only to extract and attach the clip-on ladder stored under the secondary frame, and both upper and lower sleeping areas are ready for use.
It is suggested that the adults take the upper bed; then, should their offspring prove wakeful or fractious, it is the work of moments to reactivate the remote control, causing the upper frame to descend smoothly and silently upon the lower, and ensuring a peaceful nights sleep, once the muffled struggles and yelling have lapsed into a satisfying silence.
