A chair 30 structured to assist an elderly, infirm or disabled person in rising from a seated position to a standing position or sitting from a standing position, includes protrusions 10 which extend in a direction forward and upward of chair arms 20. The protrusions 10 may be cuboidal, spherical, ellipsoidal, cylindrical and have a first surface sized and configured to be gripped and pulled on by the person during a stabilisation phase of rising or a de-stabilisation phase of sitting and a second surface sized and configured to be pushed against by the person during a straightening phase of rising or a bending phase of sitting. The first and second surfaces may be convex. The protrusions may be integral with the chair, on a rod 210, and retractable, or provided as an attachment to the seat or arm of the chair and extend forward and/or upward of a front edge of the chair. |
