"A couple have spent the past 20 years experimenting to perfect the practice of moulding trees so they grow into the shape of a chair.
Alice and Gavin Munro grow their creations upside down, in a process that they say typically takes between six and nine years, before each item is dried for a year.
The process involves training and pruning young tree branches as they grow over specially-made pieces of recycled plastic which help to shape the trees' growth."
