Firm padding prevents you from sinking into the seat when you sit and tends to have comparably few creases. Nevertheless, on some models, the upholstery fabric may need to be creased at the corners, depending on the manufacturing technique. Depending on the elasticity and thickness of the upholstery material, there may be larger or smaller creases visible; these do not constitute a quality defect. Firm padding is particularly popular in period furniture, chairs and benches. It makes it easier to stand up, which can be helpful for older people in particular.
