Group 2 support surfaces for wheelchairs and hospital beds refer to products designed for the prevention and treatment of pressure ulcers (also known as bed sores or decubitus ulcers). They provide additional support and pressure relief to help reduce the risk of developing these types of injuries. 

Group 2 support surfaces typically include air-filled or foam cushions and overlays, which are used to distribute pressure more evenly and reduce pressure points. These types of support surfaces are typically used for individuals who are at moderate to high risk for developing pressure ulcers and need additional support to prevent these injuries from occurring. 

Group 2 support surfaces are commonly used for individuals who: 

• Have limited mobility or spend a significant amount of time sitting or lying down. 
• Have a medical condition that impairs blood flow, such as diabetes or peripheral neuropathy. 
• Have existing pressure ulcers or a history of developing them. 

• Are incontinent and require frequent changes in position or need to be cleaned. 

It’s important to note that the appropriate type of support surface will depend on an individual’s specific needs and medical condition, so it’s important to work with a healthcare professional to determine the best option.
