I'm looking for a reasonably priced stool for acoustic gigs. Something that folds up would be good, comfortable for more than 2 hours and wont fall apart or have me slipping off it or buckling and creaking under 100 plus kg of weight. I'm leaning towards the Proel stool or a Haze, also known as KB009 stool. There is $27 bucks difference between the two. Cheapest is the Haze at around $42 bucks delivered. Anyone have any other recommendations or experience with the two I've listed? Do the ones with back rests actually help back fatigue or end up never using the back rest? Proel with mesh type cushion top Haze or KB009 with all vinyl cushion and slightly cheaper build quality by the looks of it.
