The Autotilt SIGMA Chair: Enabling Patient Mobility
20 May 2026
3 Available Models
The Autotilt SIGMA Critical Care Chair is available in three models, with the key difference being their weight capacity.
All chairs are designed to support patient mobility and enable safe, comfortable patient transfer using motorised positioning and powered controls to assist both patients and hospital staff. A quick-release function allows the chair to be positioned horizontally in just 3 seconds, while the forward tilt feature helps patients move safely into a standing position.
Supporting Bariatric Patients
The SIGMA 250 and SIGMA 300 have been specifically developed for bariatric patients, featuring a wider seat measuring 74 cm (29 inches) and a maximum weight capacity of 250 kg (39 stone) and 300 kg (47 stone) respectively.
Effective Infection Control
All models have antimicrobial powder coated frames. In addition, seats and padding are finished in antibacterial upholstery to support infection control and hygiene standards in critical care environments.
