Concrete is an awesome material, and I have no idea why it has taken me until now to realise this! Above are some amazing products that are really only interesting due to the material. OK some may say it is gimmicky in certain usage situations, but when a standard material is use in an interesting way, it really can give great results.
Fair enough it really does not abide by ‘truth to material’ but I feel this is the whole point of using concrete. It allows a designer to create an extremely industrial styled product, whilst maintaining a minimalistic and modern aesthetic; and can even give a simple form something new. One of the best examples of this is in furniture, where tables can be in such a simple form yet still look exquisite due purely to the material.
