Common questions
What is the DEAS score?
The Desk Ergonomics Assessment Score, Desk Doctor's product rating out of 10. Every product is scored on eleven dimensions in three layers: clinical performance, product quality and value. Tap any row in the ranking for the full breakdown. How we score.
How do I stop window glare on my screen?
Start with the screen. OSHA's guidance is to turn it so windows are at right angles to it, not behind it or in front of it, and to use blinds or drapes on the windows to cut bright light.1 Blackout curtains are the most complete fix when you can't move the desk; light-filtering curtains or blinds let some daylight in.
When does the assessment suggest them?
When your lighting feels too bright: blackout curtains are one of the fixes it offers, alongside a desk lamp with the overheads off, warmer bulbs and shading the overhead light.
How often is this ranking updated?
Scores are refreshed as products are revised and new models are scored. The ranking always reflects the current DEAS data.
Are these affiliate links?
Some are, which means Desk Doctor may earn a commission at no cost to you. Rankings are set by DEAS score alone and are never influenced by commissions.
