I have a bedroom in my house, approx 12x12 that doesn't have a closet.
It's also not large.

I found an ikea wardrobe that fit across one wall perfectly- approx 18
in deep and 6 ft wide. But the particle board shattered when I stood
it up. Say what you will, but no ikea product collapsed like that for
me before. the screws just popped the particle board right out like it
was made of potato chips.

So Ikea is out, but I cannot find a similar retailer who has a wide
wardrobe/armoire/storage type product. All the wardrobes I find are
"entertainment centers."

I've got recommendations for installing kitchen cabinetry, but has
anyone done something similar or have recommendations for non-permanent
closets in a small space?

I am having trouble finding online resources for this problem.

thanks!

Don
