Very sturdy.metal - not flimsy plastic.

It also looks nicer than the flimsy plastic ones.

I mean your only stacking paper in it but still at least its not flimsy plastic.

I actually had a solid plastic system from staples years ago (2 in fact) with a solid top that I put the phone and, modem, router, tape, stapler on, but I found I hated the dust that collected on it

I was able to throw away the cheaper plastic trays that I have been using.

Perfect to replace the cheap plastic file rack that fell off my desk and broke

all metal, nice finishwill NOT crack like the cheaper plastic onesvery smart design, efficient use of space....

It works as it is supposed to and appears to be well made.
