The mat contains a total of 70 pieces of ball, island and forest moss measuring 2.4in (6cm) each in diameter.
It feels soft underfoot and does not smell when it gets damp.
Each piece of moss is cut into a foam frame, which prevents the moss from spreading or growing out of control.
Its designer, Nguyen La Chanh, from Switzerland, says the mat is very relaxing and needs little care.
She said: "The idea was to find a new way of having your plants inside.
"Not only plants in pots quietly standing in the corner of a living room but alive plants, evolving in the house.
"I think this mat would appeal people who miss a corner of nature in their appartment - perhaps if they live in an urban environment, far from parks and nature areas.
"It's relaxing, feels lovely and soft under the feet and doesn't need much care."
Miss Nguyen is looking for financial backing so she can mass produce the mat for less than the £220 it cost her to make.
