Swing Away Frame | | Fixed Front 70-deg | | Fixed Front 80-deg |
| Swing Away Footrests swing to the side for entering or exiting the chair. They also swing to the side to detach and attach from the side. | | Fixed front ends are set to a fixed angle. They are height adjustable and the footplates fold up for folding the wheelchair. | | Fixed front-ends are usually between 70 and 90-degrees. 90-deg. is straight down and may not be comfortable for many users. |

| Since Swing Away Footrests are removable they can be replaced with other angle footrest or Elevating Legrests. The angle of a Fixed Frame is part of the frame and cannot be changed or altered. |
