Modular design makes the EasyStand Evolv the most versatile standing frame available. The Evolv is a modular sit to stand stander with over 60 support and positioning components. The base unit is functional for many users, however when more support is needed a wide variety of positioning components can be added to accommodate the most involved users.

Fits individuals from 5’0-6’2” and up to 280 lbs.
Seat Depth Range (from seat pivot) 18″-23″


The Evolv Large base unit comes standard with:

  • Two 5” Rear Locking Casters
  • Two 5” Front Wheels
  • Manual Hydraulic Actuator with Handle
  • Planar Seat
  • Flip-Up Knee Pad
  • Multi-Adjustable Foot Plates
  • Black Molded Tray with Chest Pad
  • Transfer Handles
  • Black Upholstery




The EasyStand Evolv is the most supportive and comfortable sit to stand stander available. With over 60 options and configurations, each unit can be built specifically for an individual or facility. These options, that would normally be custom modifications, allow a stander to be configured for specific needs.
The optimal standing position has been perfected in the Evolv standing frame. By strategically placing the pivot points of the stander in line with the body’s natural pivot points, options like the hip supports, lateral supports, and head support remain in place from sitting to standing, minimizing shear. When positioned correctly, the contoured seat provides a maximum over-center stretch for various body types.The Evolv also accommodates for hip and knee contractures through proper positioning of the footplates and optional independent knee pads.
Accessibility and Independence
The Evolv’s open base makes independent transfers easier. A larger Transfer Seat or Rotating Seat can also be added to make transfers more manageable. To make standing pivot or lift assist transfers easier, an optional Swing-Away Front or Removable Back can be added. The user can independently achieve the standing position with the manual hydraulic actuator or optional push-button Pow’r Up Lift.
Safety and Convenience
The Evolv standing frame provides a safe and supportive transition to standing. It allows the user to stand in three easy steps – adjust, transfer, and pump up. Both caregivers and users are more comfortable with the Evolv because of the safe and easy lateral transfer and supportive transition to standing. Don’t just take our word for it – see what others have to say about the versatility and convenience of the Evolv.
