I currently own two different trumpet stands. One is the K&M folding stand and the other is the Hercules E/Z safe trumpet stand.
K&M Folding Trumpet/Cornet Stand
However, this stand is brilliant for a trumpeter travelling to and from gigs and rehearsals. It is very lightweight and the legs unscrew and store inside the top part, which can then be stored inside the bell of the trumpet.
