There are many different types of seat cushions on the market, but not all of them are created equal. If you suffer from hemorrhoids, you need a seat cushion that will provide the right amount of support and comfort. The best seat cushion for hemorrhoids is one that is made from memory foam. This type of foam contours to your body and provides support where you need it most. It is also important to find a cushion that is firm enough to provide support, but not so firm that it is uncomfortable. Another feature to look for in a seat cushion for hemorrhoids is a removable cover that can be washed. This way, you can keep your cushion clean and free of any irritants.
