Clever and eco-conscious Convertible furniture is very popular in these days, due to small apartments. Gro Furniture’s Bam B crib is so clever, besides converting to the standard toddler bed, it then converts into a play table or desk so that you can use the crib up until your kid goes off to college. The bed is of course made of eco-friendly materials because it’s important for kids. This crib is ideal for small spaces.
