A lot of organizers we've seen are a little fussy for real-life mudrooms. Ours takes garden supplies, potting soil, pet towels and muddy boots in stride, with lots of compartments that are big enough to be useful. Upturned lips keep items stowed. Natural fir.
Anchor to the wall if stacking more than one. Easy assembly.
