When shopping for the best ergonomic executive chair, getting a chair that is suitable for the user is extremely important. An alternative is to swing the arm back, which enables the user to remove the arm when not in use. This guide will help you make a better selection.

Seat Height Adjustment:
For optimal flexibility, the seat height range should include a slightly lower and slightly higher height than your ideal setting. To give you an idea of where your seat height should be in relation to your length, seating heights up to 15″ – 22″ will accommodate users ranging from 5’0″ tall to 6’4″ tall – you can use our ergonomic executive chair, and keyboard height calculator to find the right height for you.
Some ergonomic chairs offer such a large seat height range, so pay careful attention to the seating height range of whatever chair you are considering. Many ergonomic executive chairs offer the option of height cylinders so that the chair can be ordered with the right height range for the person. The seat must have pneumatic height adjustment so that you can easily adjust the height of the seat pan while sitting on the chair. Adjusting your executive chair to the right seat height helps reduce stress on the knees and waist.
Seat Pan Size:
The seat pan should be deep enough to support most of your upper leg, but not deep enough to touch the back of your knees when you sit back in your chair. On the contrary, it should not be wide enough that the user cannot place his arms on the armrest without extending them to the side. Note for large users, weight capacity is not a good gauge when choosing a best office chair, as it is a safety measurement. Both seat size and weight capacity should be appropriate for the user. Your seat should adapt to your body.
Seat Pan Depth Adjustment:
The seat pan of the desk chair is properly positioned when it allows two to four fingers to fit between the back of your knee and the front of the seat. A proper seat depth setting allows the user to fully sit back so that the user can position the curve of the seat to match their curves while sitting back and use the wooden curve of the back of the chair. Seat depth adjustment can be done in two ways.
The seat slider is a lever mounted on the seat that allows you to slide the seat in and out while sitting on a chair. The back depth adjuster is usually a knob on the back of the chair that rotates the back in and out instead of the seat. This type of adjustment is harder to adjust while sitting, may require an assistant, and is better suited to a single-user chair.
Backrest Height Adjustment:
The backrest should slide up and down to allow the lumbar curve of the backrest of the chair to fit into your lower back (lordotic) curve. Height-adjustable lumbar support is a common replacement.
Back Angle Adjustment:
This will also help fit the chair to suit your body type. Lying in your chair supports the weight of your upper body and thus loses some weight from your lower back. Many chairs have a locking back angle adjustment that will let you find your most comfortable tilted or upright position and then lock that position. Both the pressure of the lumbar disc and the activity of the back muscles are the lowest, with a supported bending angle of 110° – 130°. Tilted poses are often preferred (Grandjean, 1988).
Back Tilt Tension Adjustment:
This adjustment knob allows you to adjust the amount of force required for bending according to your body weight. The humanescale freedom chair and liberty chair are tailored to the user’s weight and do not require tension adjustment.
Lumbar Support:
This is especially important if the user has lower back problems, or if many people will use the chair. The most basic lumbar support is adjusted vertically when you raise and lower the chair. A waist with a certain depth is acceptable if it fits you well and adjusts vertically. A chair without adjustable back height or independently height adjustable lumbar support may not be suitable for many people.
Armrests:
The armrests, at least, must be height adjustable. Ideally, the arms should be front-and-back and width-adjustable to allow a more personal fit. The pivoting arm is a useful feature as it will allow some users to better position the arms for support while typing.
Stable Wheel Base and Quality Casters:
The base of the chair must have at least a five-spoke base. The four-spoke bases lean upwards when you sit back in your chair. Quality casters will glide freely on different floor surfaces. Some chairs offer the choice between hard floor casters for use on tile, wood or laminate floors and carpet casters for use on carpets. Many chairs also offer the option of glides, which are flat, unrolled legs.
Headrest:
The headrest provides support to your head and can reduce the weight that falls on your neck. If you have neck problems, strongly consider buying a chair with a headrest.
