Ergonomics is about fit, not price. The goal is a neutral posture: feet supported, elbows near 90 degrees, wrists straight, and the top of the screen at or just below eye level.
Chairs
- Size first. Many good chairs come in sizes. Seat depth should leave two to four fingers between the seat edge and the back of your knee.
- Adjustable lumbar support at the height of your lower back's curve.
- Armrests that go low enough to sit under the desk and adjust in height and width.
- Mesh stays cool; foam feels softer. Both work.
- Warranty is a good proxy for build quality; ten years or more is common on office chairs.
Standing desks
- Height range: check that both the lowest and highest settings fit you (with your keyboard on top).
- Dual motors lift more weight and stay steadier than single-motor frames.
- Stability at full height matters more than speed; read reviews for wobble.
- Memory presets make switching easy, which is what gets you to actually stand.
- Alternate. Standing all day is no better than sitting all day.
Monitor arms and risers
- Check your monitor has VESA mounting holes (75 or 100 mm) and that its weight is inside the arm's range.
- Check the desk edge: clamps need a solid lip, grommet mounts need a hole.
Small things that help
- A footrest if your feet don't sit flat once the chair is at the right height for the desk.
- A vertical mouse if your wrist aches after a day.
- Breaks. A coffee walk is an ergonomic intervention.
