There are different types of cushions in the market and all have their benefits. However, depending upon your needs, you can choose the one that best suits you. While gel cushions take the shape of your body, they are not firm and are designed for pressure relief; the gel pillows have a contoured base, which is not present in all memory foam cushions. They are softer, low in maintenance, and stable, however, get low points when it comes to pressure relief. The LiquiCell pillows, on the other hand, are designed ergonomically using advanced technology that lets your body float by improving the blood flow and relieving pressure off your back area. These cushions are lightweight, portable, and versatile.
