Modern, Sturdy, and Perfect for Outdoor Projects
Size: 38"Height × 14" Wide
These metal pipes made fantastic table legs for our outdoor wood table. They have a sleek, modern look that feels high-end. We sprayed them with Rust-Oleum for added protection, and they’ve held up great. Solid, stylish, and functional—highly recommend for any DIY furniture project!

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.

Pretty good, take your time and install it well
Size: side table leg
Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced
