The StagePlayer is a combination folding stool/guitar stand created by Nick Vail Designs. I use a folding stool similar to this when I play guitar, and I can see the benefit to having an attached guitar stand.

Here are some of the features of the StagePlayer:

• no assembly required
• weighs only 10lbs
• fully padded and comfortable
• fits most guitars, basses, and banjos
• neck support and non-slip foam on the folding support arms
• safe for all finishes
• rugged metal construction
• holds up to 250lbs
