We're not sure if anyone else shares the same concern but we've always been afraid of coat hooks hung at kids' eye/head level. Just seems like an accident waiting to happen. But coat hooks are a great storage idea for nurseries and entryways and we love the design of these Skateboard Pegs by PBKids.
The wall-mounted pegs are in the shape of a skateboard and the "hook" is a real skateboard wheel. No sharp, poking objects!
