About the Midmark 641 Power Procedures Chair
The Midmark 641 delivers powered positioning across four axes (seat, back, foot, and tilt) with Auto-Return and QuickChair functions that automatically position the chair for patient entry and exit. Unlike manual procedure chairs, you’ll get consistent positioning every time without the physical strain on staff.
The optional One-Touch Programmability stores up to four preset positions, so you can move between lithotomy, Trendelenburg, or sitting positions with a single button press. Worth noting: the 350° rotation option with pedal lock gives you full access around the patient without repositioning.
Dual control ports (hand and foot) keep controls within reach regardless of chair position, while the foot control’s protective overlay handles repeated cleaning protocols. The removable, swivel arms lower automatically with the backrest, and locking casters add 3.5 inches of height when you need mobility.
