Sadler Stairlift For Curved Stairs

  • Unfolded, ready to use. A low footrest, sturdy arms and tilted seat make it easy to get onto the Sadler.

  • Tilting seat gently raises and lowers the user, making entry and exit comfortable and easy.

  • Immobilizer seatbelt prevents your stairlift from moving until you are securely buckled.

  • Arm isolation prevents operation of the arm control until the armrest nearest the bottom of the staircase is fully lowered.

  • Gently push the control to move up or down the stairs.

  • The chair rides smoothly up or down the stairs, and stops automatically when it reaches the far end.

  • Sensors stop the chair if it touches an obstruction.

  • Folded, the Sadler leaves room for others to walk up and down the stairs..

  • The Sadler is designed to accommodate people who find it difficult to sit down or bend their knees.
  • Engineered for stairs that turn, this chair places the user in an upright position, without unduly stressing the knees.
  • The saddle-style seat raises and lowers helping the user transfer in and out of the chair with ease.
  • Adjustable seat height: with multiple seat height options, the Sadler is installed to fit each user
  • The Sadler’s immobilizer seatbelt prevents the lift from moving until the user is securely buckled. Instead of being tucked down by the users’ hips like most stairlifts, the Sadler has a retractable seat belt that is mounted near the tip of one armrest, and which can be operated with one hand. It simply latches into a hole on the opposite armrest.
  • Downside armrest protection. For additional safety, the armrest nearest the bottom of the stairs must be lowered before the chair can be moved from the using the control on the chair.
  • A compliant control. Instead of being a hard switch, the control on the armrest is slightly soft and shaped to allow it to be pushed by many parts of the hand.
  • Stannah has the best testing process in the industry. All Stannah stairlifts are tested at full load for the equivalent of 10 years of use, and the motor/gearbox is tested for the equivalent of 20 years. This is a robust stairlift designed to serve you well.
Specifications and Planning


Dimensions measured from the wall are nominal – the addition of a wide baseboard or similar obstruction may affect the dimensions taken from this point. The dimensions are accurate, but you should add 1″ clearance for the user.

  • Weight limit: 300lbs.
  • Minimum stair width: about 29″. (The stairlift takes up less, but you need room for the users’ knees)
  • Distance between armrests: 19.6″ at the front, 17.7″ at the back
  • Depth of seat cushion: 13.5″
  • Minimum seat height from floor: 22½”
  • Maximum seat height from floor: 31½”
  • Space needed at the bottom of the stairs: about 27″ in front of first step (but chair can be folded and sent up the stairs when not in use)
  • Folded width from wall: 15½”
  • Rail protrusion at bottom landing: min. 12″ but the rail may be turned to park the chair away from the stairs, which reduces the rail protrusion to about 7½”
  • Rail protrusion at top landing: typically none, unless a rail over-run onto the top landing is chosen.
  • Width of rail: 1¾”
  • Distance of rail from baseboard: typically between 6″ and 7½”; varies with the shape of the stairs and the design of the rail
  • Speed: about 18’/minute (so about 50 seconds to ride up a typical staircase)
  • Remotes: two, one for each landing, infra-red wireless (like a TV remote with two buttons)
  • Battery life – stairlift: typically 3-5 years
  • Battery life – remotes: typically 1-2 years depending on use. 3 ‘AA’ batteries per remote
  • Service interval: annual service is recommended by Stannah and by American Society of Mechanical Engineers code
  • User maintenance required: none, but a wipe down with a damp cloth is OK for cleaning
  • Standard safety devices:
    • Seat belt: retractable seat-belt
    • Over-speed governor: required in public buildings, so we fit one to all our stairlifts
    • Safety sensors: on the footrest and both sides of chair, to stop the stairlift if it touches an obstruction
    • Key lock: located on the carriage, below the seat
