(1) Level of support
Some cushions may just support the back, whereas other cushions support other areas of the body as well, such as the hips or tailbone. Moreover, people may wish to look for cushion seaters that contain durable materials, as nondurable materials may wear away over time, reducing the level of support they offer.
Some cushion seaters have memory foam filling and cooling gels, which may provide additional support and prevent people from overheating while sitting in their chairs.
It is important to purchase a cushion seater that is the correct size for a person’s chair. People should measure the depth and width of their chairs and use the measurements to inform their choice. https://www.wwl.nhs.uk/media/.leaflets/606430365334d0.62903502.pdf
