This airplane gadget sounds the invention of someone who had to share a room with their sibling: a miniature armrest wall.
The Create-a-Space is a book-sized contraption that folds out and slides over an armrest, clearly delineating which side belongs to which passenger.
As seat width gets smaller, airplane passengers are forced to make more and more unwanted physical contact with the person in the seat next to them, according to Create-a-Space. But now passengers can keep from even gently brushing up against their neighbor by erecting a mini-wall on the armrest.
Not only does Create-a-Space keep arms on their fair sides—oh no‚ it also ensures that passengers never even have to make hip contact.
Create-a-Space is TSA and FAA compliant, according to the company (although that doesn't mean airlines would be game). It weighs only 10 ounces, so you don’t need to sacrifice suitcase weight for your full share of the armrest.
There’s no more creeping over onto the other passenger’s side. What belongs to the window seat passenger belongs to the window seat passenger—not a centimeter more and not a centimeter less.
Passengers who need to claim every square inch of their territory on the plane should consider adding the Knee Defender to their airplane kit. The Knee Defender, which has been banned on certain airlines, keeps that pesky passenger in the row ahead from leaning back their seat.
The Create-a-Space portable seat partition is available for $39.99 on Amazon. But the face of the passenger seated next to a Create-a-Space owner is probably priceless.
