Picture text suggestion:
"With 5 grips the Double Trolley is easily transformed from stool to trolley."
"In under 10 seconds you can transform the Double Trolley from stool to trolley and vice versa."



I got the Double Trolley and it works very well! It is built more firmly and so easier to move the instrument and to sit on than I thought. Among all, I'm surprised at that it can make sharp turns so I can move the instrument in narrow space like a corridor in my home. All of my colleagues admired it, and some of them said they would like to buy it.

Today, when I took this picture, there was a slight strong earthquake, but my instrument which was standing with the trolley didn't fall down!
