I got this shelving unit after doing a lot of research on best materials, pricing and manufactures. I found the exact unit at several stores and online sites. Wayfair was most definitely the the best price.   I was hoping to get something made in the US but, couldn't find any single units like this (they were more systems). However, that said this is a great unit that I have in the basement to help bring things up off the floor and organized.  I like it so much I will be buying another.  I actually used a pretty (cotton/not plastic) shower curtain (with hooks) to hang from the top shelf over them to hide and pretty up the space they were put in. They could easily be used in an outdoor area or garage as the unit material is made for indoor/outdoor. The wheels lock and unlock for ease of movement as well.
