Desk chair cushion – Ideally, you will be able to put the cushion on the chair during the later stages of upholstery so that the raw edges are tacked or stapled to the hard seat panel of the chair. However, you may want to install an upholstered cushion that fits your chair, which requires stapling after the cushion is finished. Measure the shape and size of the chair seat panel and cushion in advance to get a mattress that fits correctly.
Remove the desk chair cushion from the old chair. Turn the chair. Loosen the screws that secure the chair structure to the hard mattress panel. Remove the screws and lift the chair cushion. Turn the cushion upside down. Use a basic remover, screwdriver or chisel to remove staples from the liner paper or board and the mattress panel, if the paper is there. Put the paper aside.
Remove the cushion from the panel. Desk chair cushion and styles vary. But the upholstery fabric usually fastens to the panel with tacks or staples for upholstery. Then, remove with a screwdriver, chisel or hammer. Remove all old mattress and upholstery fabric, filling and batting. If the upholstery is stuck, cut as much as possible, or use a glue remover to loosen it. Adjust the new upholstered cushion upside down on a clean, flat surface. Place the chair panel, bottom up, on the top of the mattress. Align them so that all edges are flush.
