How much room should there be at the sides?
The seat should be wide enough to avoid squeezing the hips or thighs while still giving reasonable side-to-side support. Too much extra width can make positioning and propulsion less efficient.
Why does seat depth matter?
The user should be able to sit back against the backrest while the thighs are supported without the front edge of the seat pressing firmly into the backs of the knees.
How should the feet sit?
Feet should be supported securely on the footplates or footrests rather than hanging unsupported or being forced too high.
What should you check at the armrests?
Armrests should allow a comfortable shoulder position and should not create concentrated pressure against the body.
What are signs that the chair may not fit well?
- hips or thighs are tightly compressed;
- the user slides forward repeatedly;
- feet cannot rest securely on the footrests;
- the chair feels much wider than the user;
- frame parts rub the legs or arms;
- posture collapses to one side;
- persistent redness or discomfort develops.
Is seat width enough to choose a wheelchair?
No. Overall fit also depends on seat depth, back support, leg length, posture, transfer method and how the chair will be used.
Important: A standard retail wheelchair is not a substitute for specialist seating where the user has complex posture or pressure-management needs.
