The Hug tuba stand is design for all tubas and is adjustable to fit all players. The arms are spring loaded to easily pull apart to mount the tuba and then gently close when released to "hug" the tuba. The stand can be adjusted for both sitting and standing positions. It includes non-marring wheels - the front wheel swivels for mobility and has a lockable brake to remain stationary when needed.Size: Full size tuba, mouthpiece on left.
