If you can comfortably laze on your favourite couch at home for hours on end, why not bring that concept into the sky?
That's the thinking behind a radical airplane seat created for British Airways, which casts an oversized seat as a one-person couch where passengers can sit, sleep or spread out as they choose.
It's the innovative handiwork of London firm PriestmanGoode (company director Nigel Goode is listed on the patent as the design's inventor).
BA reckons the design is sufficiently unique to have applied for a UK patent, which is the source of these photos and diagrams.
The new design sees each passenger ensconced in a slightly curved cubicle, seated close to the window with their feet facing towards the aisle.
Passengers would adopt a forward-facing position for the taxi, take-off and landing stages of the flight.
(Note how the video screen faces the passenger so that movies can be viewed on a 'gate to gate' basis.)
Swivel around in the seat and swing out the dining table when it's time to get to work..
... or when it's time to eat.
The middle seats in this 1-2-1 arrangement can be used for shared dining if you're travelling with a friend.
This image shows a secondary location for the dining table.
An infill section of the sofa swings up to create a continuous surface between the seat and the ottoman so you can stretch out...
... or grab some shut-eye.
A draw slides out from under the ottoman where you can stow personal items such as smartphones, tablets, laptops, wallets, amenity kits and perhaps even a small purse.
So how would this 'sofa class' seat appear in the cabin of BA's most modern jets?
The patent documents show individual window seats angled towards the centre of the plane, with the two seats in the middle facing out towards the aisle.
Interestingly, BA suggests that the bulkhead facing the first row of middle seats could contain a super-sized video screen of around 40 inches (100 cm) "to provide a larger viewing screen or private cinema for the occupants of the double seat."
Seat pitch in the proposed cabin layouts varies between 42- 43 inches, while bed length is listed as 74.5 inches (1.88 metres) with a total width of 26.3 inches (66.8 cm).
As BA notes in the patent application, "there is intense competition to provide ever-greater comfort and space for aircraft passengers." And for British Airways, this could be the seat which delivers it...
