How to Choose a Chair Guide
CHAIRLINES Helpful Tips for Choosing a Chair:
*Please note that this is intended as a guideline only and not a replacement for actually trying out chairs in our showroom.
1. When sitting in a chair, the user's feet should sit flat and comfortably on the floor (or footrest) without pressure on the underside of the thighs. The knees should be bent at approximately 90 degrees.
2. The seat depth of the chair should be determined by the amount of space between the back of the knee and the edge of the seat pan. Users should be able to sit in the chair without undue pressure against the back of the knees to prevent potential circulatory issues. The back should be supported by the backrest, with adequate buttock and thigh support.
3. The seat of the chair should be wider than the hip breadth by only an inch or two to allow space for movement and clothing. The seat should not limit the ability to comfortably use the armrests or be too wide and force the user to stretch to use the armrests.
4. The angle of the seat pan should allow the user to support their feet on the floor or footrest. Seat pan angles should not cause the angle at the hip to be less than 90 degrees ( unless instructed by a physician for special needs). Forward seat pan angles should not cause excessive weight on the feet or cause the user to experience a feeling of 'sliding' out of their chair.
5. Users who require upper body mobility should choose a backrest that provides adequate back support but that does not interfere with movement such as a low-back or medium-back chair and that is not higher than the bottom of the user's shoulder blades.
6. Users who prefer reclining postures or more upper back support should choose a back rest that has a higher support above the shoulder blade area such as a high back with headres/neck support pad.
7. The width of the backrest should provide adequate support for the curvature of the user's back without causing curvature or uncomfortable pressure points. The backrest should provide support in all areas of the back without the user straining to adapt to the chair's curavature.
