After sitting on plastic buckets for years, this little rolling seat is a godsend for working on my bikes. I'm nearly 70 and I'm 6' 3"and yes, it is a little low for me with my long legs but I wouldn't trade this thing for ANY kind of bucket. It rolls nice and 2 of the wheels can be locked. I put one locking wheel on one end of the seat, and put the other one cross corner from the first one so I can lock the whole thing in place. Even though this thing is almost all plastic, it's sturdy enough to hold my 220 lbs with no problems and no strain on the wheels. This is a well thought out product and I'd purchaze it again with no regrets.
