What is the Difference Between KARMA Power Wheelchair Seats?

Choosing a power wheelchair includes a few more steps compared to choosing a manual wheelchair. The needs of power wheelchair users differ greatly therefore there is a lot of variety of power wheelchairs on the market. Whether you are totally dependent on a power wheelchair or you need a power wheelchair to just travel longer distances, there is an electric wheelchair to suit your needs. 

To understand the needs of each user, the following categories should be considered;  

Body Dimensions: The user’s body size, whether it is affected by a disability or not, will affect the choice of seats available to the power wheelchair user. 

Lifestyle (Environment): The user’s lifestyle will affect their choice of chassis they choose. Whether they are going to be using it indoors, outdoors, long, or short distances are all taken into consideration. 

Purpose of Use: In addition to improving carrying out daily actions, power wheelchairs can be a great aid for rehabilitation with the guidance of a therapist. 

Physical Condition: The reasons for loss of mobility are different for each user. First, we need to know if the user can sit up and support their upper body independently.

What type of power wheelchair seat for body size

The user’s physical condition will determine the type of seat they can choose for a wheelchair. Broadly speaking, the three categories to keep in mind when choosing a seat are;

  • the user’s body size
  • their ability to support their upper body
  • special circumstances such as amputees
