wheels broke base broke rebuilt using other parts because the seat itself is very comfortable [SEP] purchased this chair a year ago i use it exclusively to roll around my small kitchen cooking this is the fourth saddle chair i have owned and they all eventually broke because i weigh pounds of the four styles this is by far the most comfortable seat for a big man the seat is in great condition and i have combined parts in order to continue using itthe wheels broke within six months replaced them with rollerblade wheels and it was great for another six months then the base exploded into multiple small parts while moving from one side of my kitchen to the other it is frustrating to see a chair on wheels that cannot withstand the stress of heavy weight in motion i resign myself to purchasing these relatively inexpensive saddle chairs yearly but would gladly pay more for one built to last for someone my size
