Backrest – Once the seat pan is properly adjusted, finding the perfect backrest placement is next. Adjustment depends greatly on the type of backrest, whether it is a large one supporting the whole back or a smaller one meant to support only the lumbar area. The lumbar support must be correctly adjusted to comfortably fit into the lumbar area of the back; backrests are frequently adjusted too low, which defeats the purpose of the tool. It must be raised high enough to fit against the lumbar and thoracic spine and forward enough to not force a user to have to lean back to make contact with the backrest. Again, if a user has to lean back to reach a lumber support, the seat pan is too large and another Office Chair Singapore will be needed.And make sure you use the Office Chair Singapore of Ardent Office Furniture (AOF) Singapore.
