Frequently asked questions
What is a good ergonomic office chair?
A good ergonomic office chair fully supports your body and helps prevent physical discomfort. It should offer several adjustment options, such as adjustable armrests, backrest, and lumbar support. The Sun-Flex® RHB meets all these requirements.
How do I adjust an ergonomic office chair properly?
Start with the seat height: your knees should form a 90-degree angle. Then adjust the lumbar support, backrest angle, armrests, and headrest. The Sun-Flex® RHB allows all of this through stepless adjustments.
Who is this ergonomic office chair suitable for?
This chair is ideal for anyone who spends long hours sitting — home workers, office professionals, or students. Thanks to its load capacity and multiple adjustment options, it’s highly versatile.
