I have seen a cute coffee table made with cinder blocks in a bar a few days ago which has inspired me to collect some ideas about cinder blocks DIY furniture for you.
Cinder blocks come in standard sizes and they are often use in buildings because of their low cost. A block costs around 2 euros (these days 2 euros is roughly 2 pounds and 2 dollars, just to give you an idea). The holes make the blocks lighter without compromising the mechanical strength. If you like the industrial look, cinder blocks can be used as legs for beds or tables and in many other creative ways, some of which are shown below. I like the idea of using them as planters.
Cinder blocks are already quite a statement so if you decide to use them, remember to keep the decoration of the surrounding simple and according to the style. For instance, concrete goes really well with aged wood.
