The most obvious difference is definitely the appearance. On the one hand, the gaming chair is usually designed in a taller winged back when the office chair is always with short back. On the other hand, the gaming chair is usually made of leather or fabric when the office chair is mesh.
However the appearance is not the biggest difference, the comfort is. Gaming chairs are built to withstand longer use, which means they often employ materials that more users find comfortable. Take Victorage gaming chair as an example, they use eco-friendly high-density integrated foaming sponge and the whole steel frame, which aims to ensure and balance the durability and comfort at the same time. The thicker seat cushion will give users more support too. Also, there are PU leather, PVC leather, fabric for people to choose from. As for the office chair, most of them are made of mesh, more breathable compared to the gaming chair, but can’t support the users very well especially after long time sitting. It is also possible to be out of shape as time goes on.
Another difference is the adjustable parts. Obviously, the adjustable parts of gaming chair are more than office chair’s. Because gaming chairs pay more attention to the comfort, they help users find the most comfortable posture with these adjustable parts. Like Victorage Echo series gaming chairs, they are designed in 3D armrests that can be adjusted for height, depth, and width; backrests that can be reclined up to 155 degree, height-adjustable gaslift and frog mechanism. Also lumbar and neck pillows are common in gaming chairs too. All these parts are difficult to be found in office chairs.
