It is a bit heavy, it is not aluminum, but it is durable. You can trust it. Very good. Get it. And it stands on its own. You don't need to look for a place to lean it when you sit. Very important.

The bacteria is short and cannot be adjusted anymore, resulting in it being short and causing me to age. While it has 4 legs, the base is narrow with the legs very close to each other, causing it to lean. Perhaps a wider, conical base would provide more stability without the feeling that I might fall because it leans with the slightest movement
