You don't need new furniture to improve a long desk day. Standard workstation guidance — the kind published by occupational safety bodies such as OSHA — comes down to a few alignments you can check in ten minutes.
Chair
- Feet flat on the floor (or a footrest), hips and knees at a comfortable, roughly right angle.
- Back against the backrest. If there's a gap at the small of your back, add lumbar support so the chair meets your natural curve — support you're not touching is decoration.
- Elbows near 90°, shoulders relaxed, wrists straight on the keyboard.
Screen
- Top of the screen at about eye level, an arm's length away — a screen that's too low pulls the head forward and the whole spine follows.
- One screen directly in front of you. If you use two, put your primary screen straight ahead rather than permanently twisting toward it.
Habits
- Change position regularly. Guidance is consistent on this point: the next posture is the best posture. Stand, stretch or walk briefly every half hour or so.
- Bring the work to you. Move the keyboard, chair and screen to fit your body — not your body to fit the desk.
None of this requires perfection. The goal is a setup where the supported, neutral position is the easy default — and where you leave it often enough to stay comfortable.
