Will the FlexFit™ Adjustable Base Fit my frame or furniture?
Will the Home Delivery Professionals be able to get a FlexFit™ adjustable base into my bedroom?
Use the measurements to the right to ensure that the FlexFit™ adjustable base will fit through your hallways and into your room. Consider the obstacles below, which may prevent us from installing a FlexFit™ adjustable base in your home.
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?
Is your hallway wide enough to allow for turning the FlexFit™ adjustable base, if necessary, to move it into the room?
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.
