With 70% of the workforce suffering from back problems at some point in their working lives, seating is the most important purchase you will ever make when it comes to ensuring the comfort and fitness of staff and promoting productivity. In a years normal use the average operator chair will travel more than 7 miles and will be in use 7-8 hours a day, 5 days per week.
Firstly, and crucially, we need a chair that allows us to sit in a position that offers the right support for our back, so we can achieve a well supported and naturally balanced position for the spine.
Head and neck. To prevent neck muscles stiffening, a head rest should be employed.
Back. The back of the chair should allow the ‘S’ shape of the spinal column to be formed naturally and be supported. A comfortable back rest will prevent slumping and reduce stress on the spine and pelvis.
Arms. The arm rests should support the forearms. The height of the arms should allow the shoulders and elbows to be relaxed.
Body. The angle between the thighs and the torso should be approximately 90 – 105 degrees. The back of the seat should be slightly raised to prevent the pelvis from tipping backwards, this will reduce pelvic stress.
Thighs. The length and width of the thigh should be fully supported. Thighs should run parallel to the floor.
Legs. The seat cushion should be rounded downward in a waterfall shape allowing the legs freedom of movement and permitting unhindered bending.
Feet. Feet should easily and comfortably rest flat on the floor.
Weight. Torsion control allows you to adjust the tension of the tilt to suit your body weight.
Different Chair Types
Chairs come in many shapes and sizes but in general they fall in to one of six categories:
Executive/Managers Chairs. Larger chairs with tilt action movement.
Operator Chairs. The most common chairs with the maximum number of adjustable features. They have adjustments to seat height and most also have back angle adjustment. The best all round chair.
Posture and 24/7 Chairs. Operator or manager seating with additional lumbar support and/or heavy duty mechanisms to allow for use over 24 hours.
Multipurpose Chairs. Deskside, visitor, meeting room, conference room and training room use.
Reception Chairs. Chairs especially designed for the reception area.
Industrial and Specialist Chairs. Chairs for the most demanding environments such as warehouses and factories, these include specialist chairs such as high rise and checkout seating.
