Posted By Paul Leadbetter Catherine There is a good diagram in the DSE guidance from HSE but I explain the optimum seating position like this. Adjust the seat height so that the user's forearms are horizontal with the fingers on the home row of keys. If (and only if) they cannot place their feet flat on the floor (wearing their normal pair of shoes), then a footrest is needed. With the seat at the correct height, the user's eyes should be level with the top of the screen. If this is not the case, adjust the screen height. The chair back should be adjusted for rake and height so that it supports the user's back. As we are all different, it is difficult to recommend a good chair as it may not be suitable for the user you have in mind. If the user is particularly short or tall, a standard office chair may not be suitable as the range of adjustments may not be wide enough. If the user is short, don't forget about the depth of the seat; if it is too deep, the user may not be able to bend their knees when their back is properly supported. I hope that is enough to be going on with. Paul

Posted By Gavin Barr A good chair is one that the person sitting in it feels comfortable in. It helps if it swivels, moves up and down and tilts back. It may also benefit to have a foot stool if the persons feet dont touch the floor when sitting up straight. Hope this helps.
