Press material - Brief introduction
Danish double bass player Marc Grue has invented a trolley to roll the double bass on that can be transformed to a high quality adjustable stool and vice versa. Called the Double Trolley, it's the result of five years of experimentation. It is now set into production in Denmark and sold to double bass players worldwide.

The Double Trolley consists of three parts: a seat; a wheel-piece; and a stool-piece. When the three are assembled it becomes a trolley for transporting your bass. When the seat and stool-piece are combined, it becomes a fully adjustable high quality stool bolstered with genuine leather. The transformation takes less than 10 seconds!

By rolling the double bass with a Double Trolley you will always have your own stool with you without having to carry it beside the bass. You can roll it with one hand, leaving the other hand free to carry your travelling bag (or holding your girlfriends hand).

The double bass is carefully resting on the thick bolstered seat while you roll it with the Double Trolley. The big airpumped wheels easily absorbs the bumps on street walks - furthermore protecting the bass.

On www.doubletrolley.com you will find lots of pictures of the Double Trolley, comments and reviews by bass players, ordering details and more.

We have received the Double Trolley here in Canada and I'm writing to thank you for your wonderful product! So far it is working perfectly - I tested it out this past weekend on my way to orchestra - you see, I am a member of the Toronto Symphony Youth Orchestra, but I live far away from Toronto and need to take the train and the subway to get to and travel about Toronto......thank you for making it that much easier!
