Easy assembly, especially the second one! I suggest not assembling all four poles to total height before putting a shelf or two on.

This shelving unit is perfect!! Using it for extra storage in second garage. Very easy to put together.

Great shelf - sturdy - strong - easy to put together with two people. Just what I was looking for, for some extra storage in the pantry.

The shelves are very sturdy and the whole thing was easy to assemble (it can be done with 1 person but it is much easier with 2).

I GOT THE MARK 6-TIER BECAUSE OF THE WHEELS ON THE SHELVING. IT MAKE IT EASY TO MOVE AROUND IT EASY TO CLEAN THE FLOOR.

Ease of putting together. Very strong and solid. Rolls freely and easily but has a wheel lock if needed

It's easy to put together, but it is heavy. Will need 2 people to get top 3 shelves on. Rolls easily if it needs to be moved

Exactly what we needed. Easy to put together and set up. Extra parts are a nice touch. Price point is good

Very good except, one of the shelves was bent on two corners and will not lay flat. Otherwise I think it's a good product

Easy to put together and very sturdy. Additional pieces so you can make it into two 3-shelf units. I love that it has wheels.
