Extreme UltraKing bed from the designer measures an astonishing 12 foot wide by 10 foot long and is made with extra-dense coil construction, natural latex and lamb’s wool for superior support and comfort. The longest bed is designed to fit through any door….yes because it is put together inside your bedroom. Though, it’s obvious that you need to own a palace to accommodate this monster bed, but, in case, you own one get ready to spend in five-figures to own this thing!
