Amazon.com: 48x24x76 Heavy Duty Wire Shelving Rack with 4" Wheels, 4000 LBS Capacity, 5-Tier Adjustable Metal Shelves for Garage, Kitchen, and Commercial Storage, Chrome, NSF Certified, Crescent : Musical Instruments

This cart really needs 3 people to put it together. My box was missing the needed small wrench but I made do with one I had. Also the instructions could be better. Some things we just had to figure out on our own through trial and error. The reason I say that you really need 3 people, is because unless you plan to climb a ladder at the end, you'll need a tall person to add the top shelf. I'm 5'1 and my sister is 5'3 and we couldn't get the top shelf on.

UPDATE: we were so impressed with this shelf that we bought the smaller shelf for another project. Excellent quality!! Well worth the price.This is by far the best metal shelves I have been able to find. I was skeptical ordering online but the shelves were exactly as they were described. It is very sturdy/heavy duty, the shelves are well enforced, and the wheels lock very easily. The shelves have to be put together but, was an easier process than we anticipated. Highly recommend these shelves. We are considering a second purchase

We had a similar-sized shelving unit, only without the wheels. We found that we would have to move it occasionally and it gradually became wobbly. This unit is stronger and much easier to move. It was relatively easy for me to assemble by myself, but I think it would have been easier for most people to have someone helping.
