a little tricky to assemble . works great.Easy & quick to put together with a rubber mallet & include little wrench; sturdier than I'd feared for a good price, too. I'm now organized at my kitchen table! Rolls right underneath for immediate filing of what came in today's mail, instead of having a pile of paper develop on the table waiting for me to file in the back room. Wish I'd gotten it years ago.This item is perfect for my needs. Assembly instructions were confusing but was able to figure it out for myself. The unit is exactly the right height for my needs. Sitting in my desk chair I can look down and see every tab easily.
