### What type of bar stool is best for overweight individuals?

The best type of bar stool for someone who is overweight to sit in is a floor mounted stool. This type of stool is securely attached with bolts to the floor beneath it, ensuring better support and stability. If you don't want to bolt down your stools, your next best option is to get a four-legged stool. Four-leg bar stools disperse the weight of the person sitting on them evenly. On the downside, four-leg stools have a higher risk of tipping over.
