The Martin Innovations Zero-Lift (chair top, table bottom) is aimed at hospitals where non-ambulatory patients are examined regularly.
The chair seat has a latch at the bottom which helps convert it to a table that can hold up to 600 pounds. This means patients don't have to be lifted, even obese patients.
As a table it can be easily manipulated by a single operator into what's called the Trendelenburg position, with the feet higher than the head. Plus it can rotate 330 degrees.
The various parts of the chair-table measure 73 inches, unfolding over the base so the patient can be laid down flat.
