The treadmill is not so heavy and weighs only 86 lbs (39 kg). The assembled machine can be moved by two persons with the help of a transportation wheel.
When the machine is unboxed and set up, it doesn’t acquire large space like commercial treadmills.
The unit is 57’’ (145 cm) long and 27’’ (69 cm) wide. It is suggested to leave two feet of space on each side of the deck and at least three feet at the rear for easy and safe usage.

Incline
There is no incline facility available with the Sunny SF-T7971 treadmill. But the deck is not completely horizontal and is approximately inclined by 1°.
