It’s super easy to put them together. It’s very stable to put it on the ground. I would like to order another one for my storage room tooI added baskets to 3 of the 4 levels and it fits perfect in the corner under the counter. I use it to keep electronic cords, chargers, note pads, scissors and other little things I don’t want ending up on the counter. It’s perfect!!Fast shipping, quality product, easy to assembleThis 3-Tier Adjustable Shelving Unit is smaller than I thought. I was planning to use it in my kitchen because my kitchen is very small and I lack a pantry. But it's a little bit small, so I put it on my screen porch to put some miscellaneous things. And it is really very Sturdy. I put two very heavy flower pots on the first layer, and it is still very solid. So far I am satisfied.I buy this shelf to my brother for gift. He said she put it next to his bed. It is a perfect size that he don’t need to get up for water or something. Also, the material is super strong and I highly recommend.
