The Lawn chair/couch is a fantastic DIY kinda furniture for your garden. Get rid of every bit of metal or other all-season resistant out door furniture and grow your own line of green chairs and couches. All you got to do is arrange for 240 liters of soil to fill the frame and then spread the grass seeds evenly over the dirt. Press ‘em hard and water them a bit too. As the grass begins to shoot out after 10 days, once it has reached at about10cm, trim it for a neat green chair. You can go innovative by adding frames as per your imagination and requirements too. How about a green table and a few bar stools too?
