If you work at a desk, your chair is the piece of furniture you use most. A well-fitted task chair supports your back, keeps your feet and arms in a comfortable position, and makes it easier to sit well through a long day. A poor fit tends to push people into slouching, perching on the edge of the seat, or reaching for the keyboard.
Here's what to look for, and how to set up a chair once you have it.
How your chair affects your posture
When a chair doesn't fit, your body compensates. A seat that's too high leaves your feet dangling and puts pressure behind your thighs. A seat that's too deep keeps you from reaching the backrest, so your lower back loses support. Armrests that are too high push your shoulders up toward your ears.
Over hours, those small compromises add up to stiffness and discomfort. Ergonomic seating is designed to let you adjust the chair to your body, rather than adjusting your body to the chair. No chair is a cure-all, though. Moving, changing position, and standing up regularly matter too.
The adjustments that matter most
Seat height
You should be able to sit with your feet flat on the floor and your knees at roughly hip level. A pneumatic height adjustment with a good range lets the same chair fit taller and shorter users.
Seat depth
A seat slider moves the seat forward or back so you can sit against the backrest with a small gap between the seat edge and the back of your knees. It's one of the most overlooked features, and one of the most useful.
Lumbar support
Your lower back curves inward naturally. Adjustable lumbar support, either built into the backrest or as a movable pad, helps hold that curve so you don't slump.
Armrests
Look for arms that adjust in height, and ideally width or angle too. Set right, they let your shoulders relax and your elbows rest near a 90-degree bend while you type.
Recline and tilt
A tilt mechanism with tension control and a lock lets you lean back while reading or on calls and sit upright for focused work. Being able to shift positions easily is part of good posture.
Materials and build quality
Mesh backs breathe well and flex with your body, which many people like in warm offices. Upholstered seats with quality foam hold their shape and stay comfortable over time. Either way, check the base, casters, and controls. Commercial-grade chairs are built for daily, multi-shift use, and a strong warranty is a good sign of durability. Browse our task chairs and executive seating to compare styles.
Setting up your chair the right way
Adjust the seat height so your feet are flat and your thighs are about level.
Slide the seat so your back meets the backrest with a little space behind your knees.
Position the lumbar support at the curve of your lower back.
Set the armrests so your shoulders are relaxed.
Adjust the tilt tension so leaning back feels supported, not loose.
Check your desk and monitor. The top of the screen should sit at or slightly below eye level, about an arm's length away.
If your desk height can't change, a sit-stand desk or a keyboard tray can help bring everything into line.
Try before you buy
Comfort is personal, so the best test is sitting in a chair and working through its adjustments. For a whole team, choose a model with a wide adjustment range so it fits many body types, and consider a few sample chairs before ordering in quantity. Chairs such as the mesh task chair in our catalog show what a full set of adjustments looks like.
Seating for different roles
Not every chair needs the same features. People at a desk all day benefit most from a fully adjustable task chair. Managers who split time between computer work and meetings often like a mid- or high-back executive chair with good tilt control. Reception, guest, and conference chairs see shorter sits, so comfort and durability matter more than a long list of adjustments.
