The Original Silent Spin Seat rotates silently - 360 degrees on our slider system which has no moving parts. It's extremely quiet in all types of weather, fits all standard buckets and on any flat surface and is ideal for hunting, fishing, stadium or bleacher seats or any other recreational activity. The shape of the 3/4 Ice Seat leaves an opening in the top of the bucket for easy access inside. It's great for ice fishing, sports equipment and many other outdoor activates that require multiple pieces of equipment to be moved around. This seat also fits all standard buckets.
