Office Chair Guide – What do these features really do?

/ / General Information

You see it everywhere, people talking about office furniture like it’s a weapon. This Ergonomic, 3-Lever Mechanism, Synchro Knee Tilt, 10-points to Gryffindor chair. We have broken down all those key terms to help you know exactly what you’re buying.

Tilt Tension

Tilt enables the user to recline backward to a set limit defined by the chair’s mechanism. The tilt tension knob increases or decreases the amount of force needed to make the chair recline backwards. The taller or heavier a person is, the tighter the tilt tension needs to be.  If the Tilt Tension is set too light for an individual they may have the sensation of fall backwards when they sit down. A smaller person may be unable to tilt the chair if the tensions is set too tight.

Tilt Lock

Once a chair is locked in a tilt position it cannot be unlocked until the user reclines or tilts back a few degrees further relieving pressure from the lock bar or pin. This allows the chair to reset back to the original position. Tilt lock is used to completely lock out tilt when the chair is in the upright position.

Synchro tilt

The synchro tilt control allows the backrest of the chair to recline twice as fast as the seat cushion, at a 2-to-1 ratio, instead of the traditional rocking chair recline, where the seat and backrest recline at the same ratio. This allows the user to recline while the front edge of the seat stays more level to the floor. This allows the users feet to remain reasonably flat on the floor. The greater range of movement created increases user circulation and helps with redistribution of pressure points during the day.

Synchro knee tilt

The synchro tilt control allows the backrest of the chair to recline twice as fast as the seat cushion, at a 2-to-1 ratio, instead of the traditional rocking chair t recline, where the seat and backrest recline at the same ratio. The pivot point is located near front edge of chair, in comparison to your traditional synchronized tilt which is located towards the centre of the chair. Synchronized knee tilt combines the limited front rise of a knee tilt chair with the smooth, responsive motion of synchro-tilt. This allows the user to recline while the front edge of the seat stays closer and more level to the floor, allowing the users feet to remain flat on the floor while in a more relaxed position.

Seat Slider

The seat pan is the most fundamental part of any chair as it helps support and distribute all the weight evenly. The Seat slider feature allows the user to adjust the seat pan to suit them. A useful tool for chairs with multiple users as every user can adjust the seat to better suit themselves. When adjusting the seat pan you should allow a few fingers gap from behind the knees to the chair front. Ensure the gap is not too large or else your thighs will not be support properly.

Ratchet back

Ratchet back height adjustment eliminates the use of a knob to adjust the chair back height. The height is controlled by simply raising or lowering the backrest to the desired level. It is then locked into position by the chair frame.

Drafting Kit

Convert any standard office or task chair with the Yes office drafting kit. Ideal for higher work stations, or use with a sit-stand desk to create an easy transition between sitting and standing. Each kit includes a 220mm chrome gas lift and chrome foot ring with manual height adjustment.

2-Lever Mechanism

A 2-Level Mechanism allows the user to adjust the back tilt and seat height independently. A 2 Lever mechanism seat cannot adjust the seat tilt/angle.

3-Lever Mechanism

A 3-Lever mechanism enables the user to adjust seat height with gas lift, back rest angle/tilt and seat angle/tilt. The 3-lever mechanism allows the user to specifically position the chair to achieve their ideal ergonomic seating position.
