Mobility Assistance Sling (MAS)

Product Description and Instructions for Use

The Mobility Assistance Sling (MAS) is an easily carried and deployable adjunct for lifting and moving people with mobility challenges. It is intended for use by trained rescuers, healthcare providers, and other professionals with specific training for lifting and moving people. When determining how best to place and lift or move a person using the MAS, users should refer to their training and local protocol for decision making purposes. 

The makers of the MAS do not guarantee or imply that any of the recommendations and techniques discussed and shown in these instructions will be best suited, or even allowed by your local protocol, for your particular situation.


The MAS is not intended to be used to treat an injury. The MAS should not be used to move someone who is suspected of having an injury.  The MAS is not intended to stabilize a person in any way that may be construed to be aiding in the treatment or prevention of any injury or illness. 

The MAS is intended to be used by trained rescuers and healthcare providers for the purpose of assisting someone to their feet or to a seated position when that person can’t do so on their own. The MAS provides handles for lifters to lift with instead of having to pull and lift using the person’s arms or body to grasp on to.

The MAS is safer to use than other close lifting belts or harnesses because it gives lifters the option of choosing the handles that are ergonomically at the best height or distance from the patient so as to reduce the risk of a back or shoulder strain on the lifter. 

The embedded plastic insert in the base of the MAS keeps the sling open at a full 9” so it doesn’t dig in to the person being helped. It also provides enough rigidity to enable the user to tuck the MAS under a person without the need to roll or rock the person excessively. 

Design Features

The MAS incorporates several design features that assist in the task of lifting a person to a sitting or standing position while also reducing unnecessary strain on the users.

  • The carrier of the MAS is made of a heavy weight, coated nylon fabric. This material is extremely durable and resists tearing.  It is machine washable.
  • The embedded plastic insert flexes with the person being lifted. The primary purpose of this insert is to aid in the proper placement of the MAS under or around a person, and to keep the carrier from bunching up once it is in place.
  • The long length and multiple handles allow MAS users to position themselves as close or as far from the patient as necessary in order to lift using correct ergonomic positioning. This distribution of handles also allows multiple users to lift a person cooperatively. 

Using the MAS

The Mobility Assistance Sling kit can be used to assist a patient of any size or age.  Each Sling can be used to lift a person of up to 400 pounds. To accommodate larger persons, two slings can be used at the same time. 


The MAS does not provide any mechanical advantage and it is up to the user to ensure that adequate personnel are available to safely lift and move the person needing assistance.

The MAS comes in a carrying case as part of a two (2) unit kit:

When you have decided to use the MAS, remove one or both units from the case. You will notice that one side of the MAS has a total of eight (8) handles sewn to it. The side with the handles should always be positioned facing AWAY from the person being lifted.  The opposite, or smooth side, of the MAS is intended to be positioned facing toward the person being lifted.

The MAS may be used in several different positions. Determine the best placement for the MAS, taking into consideration the person’s size, age, location, obstacles, and health conditions. Some situations may benefit from the use of two or more MAS’s at the same time.  Here are some suggested uses:

  1. Seat placement – For a person who is able to sit up, the MAS may be positioned under their buttocks or upper thighs. The plastic insert at the center point of the MAS can be used to assist in positioning the MAS appropriately under the person.  Two lifters then assume ergonomically safe positions to lift from on either side of the person being lifted. Each lifter grasps an appropriate handle. As the lifters stand, the person is lifted to their feet.
  1. Under arm placement – For a person who is able to sit up but access for placement under the buttocks or upper thighs as described above is not practical, the MAS can be positioned under the person’s arms. To do this, center the MAS on the patients' back just below the shoulders. Alternatively, for some people it may be more advantageous to position the MAS with the center over the patient’s chest.  Next pass the ends of the MAS under each arm and then fold them up over the shoulders. This positioning of the MAS will allow two or more rescuers to grasp handles and lift in a position that is ergonomically correct for their height and distance from the person being lifted. The embedded plastic insert in the center of the MAS helps to limit “bunching” of the strap across the back or chest, which can be uncomfortable for the person being lifted. 
  1. Combining Seat and Under Arm Placement – In some circumstances it may be advantageous to use one MAS in a seat placement and a second MAS in an under arm placement. Using two MAS’s together in this fashion allows for more lifters to work together to lift a person from multiple points. When this is done, it is important that lifting effort is coordinated in such a way that the person being lifted is moved safely to the desired position. 


Rescuers should always ensure good lifting techniques are used and verify that the person being lifted is being supported, manually or with the MAS, in a way that they cannot fall back to the ground or floor while they are being moved. 

Cleaning Your Mobility Assistance Sling

If your MAS becomes soiled it can be easily cleaned. Remove the plastic insert through the hook and loop pocket closure and place the remaining carrier in a washing machine.  Hand-washing is also acceptable. Use warm water with a mild detergent. Allow the MAS to hang to dry completely before replacing the plastic insert and returning it to service.
