Room Entrance
Once inside the room, is there anything obstructing the Home Delivery Technicians from maneuvering the FlexFit™ adjustable base into the preferred area of the room for assembly?

Hallways
Is your hallway wide enough to allow for turning the FlexFit™ adjustable base, if necessary, to move it into the room?

Staircases 
Due to the weight of the FlexFit™ adjustable base (up to 5 times heavier than a traditional box spring), it cannot be lifted waist high or over staircase railings or ledges to arrive at the desired destination.

Freight Elevator
Measure the height of the entrance to your freight elevator, as well as the depth and height of the inside of the elevator. If you live beyond the third floor in an apartment building or condominium and a freight elevator is not available, an additional charge may be assessed and delivery may be delayed if this information is not received in advance.
