Do you deal with visiting family members during the holidays that more than overstay their welcome? This year try putting them up in one of these Podtime tubes, they'll quickly get the message that maybe they should have booked a hotel instead.
They're not exactly ideal for those who suffer from claustrophobia, but they are intended as a way to maximise the occupancy of a given space -- while still giving everyone a bit of privacy -- and they're actually not a terrible idea. What's most impressive is that they actually arrive flat-packed for easy transport and storage.
Multiple units can be stacked on top of each other like a set of bunk beds, and while the base unit will set you back over $2,100, it can actually be customised with added amenities like LED lighting, a lockbox for luggage, a TV and DVD player, and even a rudimentary sound system with alarm. So come to think of it, these actually might be more luxurious than some inner-city pre-Federation houses.
