Sturdy piece
Size: 24 Inch, Color: Retro Grey Oak-light
Easy to put together. I bought to use as a spice rack in a small kitchen. It's a heavy piece. Can hold quite a lot.

Style: H-shape, Size: 38 inch
Legs seem decently thick. They could be a little sturdier. The paint has stayed with no chips or flakes. Color has not faded. It sits at the perfect height for a desk. Screws and hardware do the job. No welds to speak of, everything screws together. I’ve used these for a year and a half as a school desk and has held up well. I took a sheet of project board with stain and polyurethane as my top. Works excellent

Very sturdy legs!
Style: Zig Zag, Size: 28 inch, Style: Zig Zag, Size: 28 inch
The legs are very well built and good looking, however, the screws included for installation are only 9/16" long which is not nearly enough for table legs of this size. I installed the legs on a 30" x 83" live edge oak tabletop that is full 2" thick. I purchased 1 1/4" screws for the install making the table very solid.
