It fits my gaming chair perfect. The chair although top of the line has a hard seat pad. This pad helped with long hours of gaming. Not perfect but close to it for pain relief and comfort. However like any add on pad it raises the height of the seat. Not a problem as arms are adjustable but changes how your back fits the neck and back. Still for me not a problem as the chair is a high backed model with adjustable head/neck rest. The problem with most pads are they are wider than long. I needed either square or longer than wide. Like stated this fits my chair perfect. I have a Secret Lab Omega chair. ..More
