Concrete works just as well for an iPhone dock as it does for an iPhone Case. Its not only aesthetically pleasing, but also heavy and quite durable against everyday wear and tear. The Massive Dock ($80) by Hardwrk is one such iPhone dock worth mentioning. Hand casted from concrete, the Massive Dock fits any iPhone 5, 5c, or 5s, and is heavy enough to easily mount and dismount your device from with only one hand.
