The only difference in the wire shelving is the price they both work the same.
Closetmaid vs rubbermaid closet systems.
If you want for example closetmaid shelves with rubbermaid drawers you can mix and match however you like.
If money is not a concern then buy the elfa built like a tank will last forever and looks better than the others with the right accessories.
Closetmaid required a lot of cutting to fit the components and there was indication of problems with the pvc coating.
I really liked the titanium color and settled on the rubbermaid system.
Elfa was orders of magnitude more expensive.
I like the closetmaid wall brackets better than the rubbermaid they are easier to install.
Rubbermaid brackets will fit into a closetmaid standard and vice versa.
Closetmaid shelf supports and shelves will fit on the rubbermaid or elfa vertical hangers and vice versa.
Rubbermaid is the least sturdy of the three but does the job.
My closet is 9 5 ft x 6 5 ft.
The closetmaid and rubbermaid systems are actually so similar they can be used together.
