Like I know my old one.
Format: Hardcover
It’s an updated version from my first one.1994. Was a great reference book than during my residence time and is a great reference now. Every dollar worth.

nice sturdy frame
We had a piece of actual wood lane from a bowling alley that i wanted a table made out of. Which made it weigh about 400 pounds, guessing. Our biggest worry about this is the frame holding it up with grandkids around!!! And being able to move it to sit behind it or clean around it when needed. This was what we decided on. Tim said it was super easy to put it together. The height was just a tad taller than our chairs, but there are pieces that can be taken out to accommodate this. When i told my husband it had wheels on it and definitely would aid moving it around. He said oh yeah, that's going to work real well with the weight of this table. And trust me it was said very sarcastically. So, that these worked as well as they have, really impressed him. We have friends that we gave a piece of lane to so they could make a bar in their kitchen out of it. He bought some pipe in town and he paid a heck of a lot more money out than we wanted to put out. So, we were extremely happy to find this. It is sturdy, great value and we are all very happy with it and it looks great! I highly recommend it. I think no matter what you are going to use it for, it is going to fit into any decor.

Quite good!
Quite a solid set of legs. It little flimsier than I had hoped for but we are not moving the table we built around much. The wheels are also quite small. I would purchase again though!
