DSE Compliant Seating for UK & Ireland Employers

Under UK and Irish health and safety law, employers are required to provide suitable seating as part of a properly assessed DSE workstation. JH Chairs are certified to UKAC-5459, the UK standard for office chair performance and durability, and are designed to meet the requirements of a DSE assessment, supporting correct posture, adjustability, and lumbar alignment across a full working day.

If you are setting up new workstations, reviewing an existing setup, or replacing chairs that have failed a DSE assessment, our range is built to meet the standard rather than approximate it.
