If you’re looking for some inspiration for DIY furniture, take a look at Recession Design. It’s a collective of designers who come together to create unique DIY furniture designs using commonly available materials that can be easily assembled with simple tools. They have all kinds of quirky and simple designs like this chair made from pipes and a rubber doormat.
They also share how-to instructions (in Italian but there are lots of pictures and Google Translate for the rest!). For more DIY furniture ideas, you can also take a look at my Pinterest board.
