Bottom half easy to put together. Follow direction exactly. Top half tricky, almost need two people. Once I put the first one together, it is very sturdy and holds lots of weight.

I like the shelves. They seem durable. However, putting the corner posts together was a problem. A design improvement is definitely needed to securely attach the corner posts.

Once they are up, they are good. Putting them together isn't easy. Adding the second tier is a true balancing act. The best use it to make two lower shelving units. They hold a lot of weight.

SUCKS....VERTICLE CORNER PIECES ARE IN TWO SECTIONS. FORGET ABOUT ADJUSTING THE SHELVES LIKE YOU WANT THEM...AS PICTURED IS PRETTY MUCH IT....WOULD HAVE BEEN AN EXTREME PROBLEM TO CONNECT TOP AND BOTTOM SECTIONS SECURLY...

Good units. Not as heavy as I was expecting. When assembling make sure you are on a level hard surface and follow the directions. You'll think they're going to be flimsy when you start but every piece you add stiffens it up. Happy with end result.

Shelves are great! This particular set i bought didn't have braces in-between the side bars. it was a little challenging to get together. i bought one more and it did have the braces and was so much easier. but i really like them.

The upper half is almost impossible to attach to the lower half. Once it is together and you try to move it it will fall apart. I have had to take most of it together. Bought two and will return the other one.

Bottom half was not bad. Trying to attach the next bracket on was awful. Wouldn't hold well. Needed another person. But still, it worries me that the top part will not be stable.

When Purchased, I was given a "arrives by" date of Mar 29. The items were not even received by fedex until Mar 29. Very disappointed - You cannot depend on delivery date.

I was hoping for something with a bit heavier metal framework and the connection engineering is a little marginal. If it collapses, I will report back. Made in Chicago to the highest Chinese standards.
