Chair - Overview

Backrest:

• Adjust backrest height to support lower back (curve in

backrest should match with curve in lower back)

• Tilt backrest between 95- 110°

Arm Rests:

• Adjust armrest height to support arms when shoulders
• relax. Elbows should be at 90-100°
• Make sure arm rests do not restrict access to desk or

computer Seat:

• Allow 2-4 fingers of space between the edge of the seat

and the back of legs

• Ensure user is sitting with buttocks all the way to the

back of the chair

• Adjust seat height so elbows are 90-100 when working
• n desk and knees are 90-100°
• Use footrest if feet are not fully supported on floor

Even with the best set-up, you need to get up & move around frequently

The Chair: Height

Seat Height – Adjust height so that feet are firmly supported – Knees ~90 – if you are not able to reach your keyboard and mouse you may need a keyboard tray

• r raise your chair and use a footrest

– When standing, the seat height should be just below crease at the back of your knee

Chair: Backrest Height

Backrest Height & Lumbar Support:

• Adjust lumbar support to fit the small of

your back

Note: on some chairs the lumbar support is adjusted independently of the backrest and on others the backrest is raised up and down

• Backrest height should be ≥17” (WSBC)

Chair: Backrest Angle

Backrest Angle:

• Tilt/recline backrest up to ~10ᵒ

A reclined back posture reduces pressure on the disc but you must also be able to reach your keyboard and mouse

Chair: Armrests

• Adjust armrest height to support arms when

shoulders relax. Elbows should be at 90-100°

Keyboard:

• Keyboard & Mouse should be slightly below elbow

height √ If not: Lower Desk OR Obtain keyboard tray (preferred) Or Raise chair and use footrest (preferable for bi-focal users only)

Keyboard

• Position keyboard directly in front of you
• Keep wrists neutral, i.e. hover when typing
• Keep keyboard flat or slightly pointed down away from

the user

Mouse

• Place mouse directly beside the keyboard
• Clean mouse as needed
• Use keyboard short-cuts
• Adjust mouse speed as needed
• If you have to reach for the mouse, consider:

– Mousing on the left – Using keyboard with separate numeric key pad

Mouse Settings

• 1. Pointer Options-Speed
• 2. Primary/Secondary Button
• 3. Scroll Wheel Speed

Mouse Settings

• To Increase Mouse Speed
• Start Menu---Control Panel

Mouse Settings: Pointer Options

Pointer Options --- Fast

Monitor

• Top line of the text at ~eye level

– *Bi-focal users will want to have their monitors lower

• Distance: ~ arm’s length
• Enlarge font: [ctrl] & scroll on mouse wheel
• Position monitor perpendicular to window/light

– Use blinds to control outside light and limit glare Tip: Enlarge Font: [ctrl] & scroll on mouse wheel

Laptop Work

• Limit laptop work to <2hrs/day
• If working from laptop for longer:
• Use external keyboard, mouse & monitor
• If external monitor not possible, raise laptop monitor

Paper Documents

• If you frequently refer between paper and computer

documents, consider using a document holder (or prop up materials on slanted binder)

Telephone

• Position phone on the left (if right handed): this will

facilitate holding the phone in your left while using your right hand to mouse

• If frequently on the phone, particularly if calls require

reference to paper or computer, consider using a headset or speaker phone option

Stretch Breaks

• Research suggests that taking an extra 5 minute break

every hour can significantly reduce symptom reports without negatively impacting productivity

• Those who didn’t take breaks were found to work at a

slower rate and make more errors in the last hour (7.5hour shift)
