These table legs are made of "jointed", threaded, 3/4inch steel pipes and it is imperative that they are assembled correctly and evenly; if not, the table will be wobbly and unstable. Need to ensure that the joints are fully tight. The assembly instructions are vague, so you may face some frustration during assembly if you're not too mechanically inclined. It is possible to modify the design of the legs to meet your specific needs, but you may need to purchase additional 3/4 inch piping and couplings at your local plumbing store. Good luck!

Easy to put together

Great! We had to buy extensions because I wanted a higher table but it worked great.

A good idea that didn't work out

The pieces are not labeled at all, the paint on the threads makes it difficult to get a good tight fit between the pieces, and the way the pipes are screwed together there are two opposing corners that always bow in an make it look like it's going to fall in. It's also really difficult to make level. I really wanted to like this because it fit EXACTLY what I wanted to use it for, but I just can't trust it long term which is why I'm giving it 2 stars.
