The home office journal / Practical decisions
A chair should fit you.
Use adjustments and a real sit test to narrow your shortlist.
By Office Home Supply editorial · Updated 2026-10-10 · 3 minute read
Begin with fit rather than a brand or a claimed ergonomic label. OSHA recommends trying different chairs before buying. A useful sit test is to adjust the chair at the desk height you use, with your usual keyboard and mouse position.
Check that your back rests against the backrest and your feet have stable support on the floor or a footrest. The seat should support your thighs while leaving the back of your knees free of contact with the front edge. Height and seat depth adjustment help different body sizes reach that position.
If you use armrests, adjust them so your shoulders remain relaxed and your elbows stay near your torso. Check that they let you move close enough to the desk. Casters should suit your flooring, and the base should remain stable.
Before ordering, write down the seat dimensions, adjustment range, configuration, and return conditions. Our editorial suggestion is to photograph your current setup and note the single fit problem you most want to improve. No chair in this catalog has been independently tested by Office Home Supply.
Separate your adjustments from the product's limits
Start with your existing chair at the desk you actually use. Note whether you can support your feet, keep the keyboard reachable and move the chair close enough without the armrests meeting the top. A new chair should address a specific mismatch. A high back alone does not solve a seat that is too deep, and an adjustable headrest is not the same as adjustable seat depth. Write down which controls you need before comparing model families.
Three useful comparison questions
The IKEA FLINTAN record identifies optional arms; verify whether the merchant's package includes them. The MARKUS medium record identifies an integrated headrest and manual tilt tension, which is a different adjustment package. Staples Hyken provides a published seat depth and seat width for its black model. Use those exact model-specific dimensions as comparison inputs, not measurements of every mesh chair. If seat depth is missing for another candidate, leave that comparison unknown until the manufacturer answers it.
Give fit decisions room to change
Read the merchant's current trial, assembly and return terms before committing to a chair. Identify how you will move and assemble it in the room. A showroom trial, when available, is more useful for a personal fit decision than counting features on a specification sheet. Once the chair is installed, adjust one thing at a time and record the setting that worked. This article discusses setup choices and manufacturer specifications; it does not establish that a chair treats pain or prevents injury.
