About
A toroid is a ring-shaped geometric surface formed by rotating a shape around an axis outside of it.
Because a toroid is an abstract mathematical shape, real-world examples range from microscopic magnetic cores to massive fusion reactor chambers. When the revolved shape is a circle, it forms a specific type of toroid known as a torus, which looks like a common donut. Revolving a square or rectangle instead yields a flat-sided ring with distinct edges. Its total volume varies widely based on both the diameter of the central hole and the thickness of the ring.
From Wikipedia
In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface.

Quick answer
This toroid model spans 6.5 feet (1.98 m) across, stands 2.8 feet (0.84 m) tall, and weighs 331 pounds (150 kg). That width makes it roughly as long as a standard three-person sofa.
