Re-experience your youth in an amazingly annoying fashion with a “scaled up furniture” business featuring gigantic chairs and tables!
Almost everything in the world is designed for people of average adult size.
As a result, most everyday objects (furniture, stairs, door handles, etc.) are a totally inconvenient size for children or the extremely short.
This is somewhat surprising, since everyone spent many years facing these problems as a small child.
But it was so long ago that no one really remembers! (This is also a classic example of the market failing to address the needs of a demographic with zero purchasing power.)
Here, we propose re-furnishing a shopping mall so that every object is sized to give you (as an adult) the approximate impression of scale that a three- or four-year old would have.
In other words, we approximately double the size of everything in the mall in all three dimensions (e.g. a 3-foot high table is now 6 feet high, and doors are 15+ feet tall).
The building would also need to have an exceptionally high ceiling in order to accommodate the larger furniture (see Figure 1).
Additionally, if this “everything is enormous” business were to sell food or beverages, those should also be scaled up (Figure 2).
Since there are so many malls that have gone out of business due to the convenience of Internet shopping , there should be plenty of abandoned real-estate that can be repurposed for this plan.
PROS: Provides useful perspective to product designers. Also allows people to re-live their childhood in the most inconvenient way possible, thus saving them from unwarranted nostalgia.
CONS: The potential for breaking bones in this out-of-scale environment is extremely high. Not everything scales up in a strictly linear fashion (e.g. a fall off a 6-foot-high table would be more than twice as injury-causing as a fall off a three-foot-high table).
 (Some people dispute this, and suggest that another factor could have caused it, such as haunting by ghosts.)
