When large or heavy items cannot easily get in via the stairs or the lift. Think of a flat on a higher floor with a narrow stairwell, or a sofa or wardrobe that will not fit round the bend in the stairs.
A furniture lift also saves a lot of time and prevents damage to the stairwell and furniture. Give clear details of the floor and the situation at the stairs, so we can see whether a lift is needed. More about this in moving into a flat.
