Pressure ulcers can form in as little as two hours and present a very serious problem for the NHS, with alarming NEW 2014 Sidhil Logo-03statistics in terms of prevalence. More vulnerable people may require 24 hour pressure care to protect skin surfaces even when they are seated during daytime hours, ensuring optimum and continuous protection.

Pressure ulcers can easily develop where prolonged periods of sitting are necessary, in particular where the individuals concerned are unable to reposition themselves or are unable to feel discomfort due to their conditions. This includes patients who are acutely ill in hospitals or where there is a long term history of prolonged sitting, such as in the aftermath of a spinal injury.

Sidhil static and dynamic cushions have been developed specifically for applications in the acute environment to match a full range of clinical requirements. The company offers a comprehensive range of dynamic and static seat therapy cushions, many of which double up with dynamic mattress systems to run from existing pumps, reducing initial purchase costs and saving space around beds in hospital wards.

Dynamic seat cushions

Dynamic seat cushions are designed to periodically offload pressure on vulnerable areas of tissue without any requirement for physical movement from the user, using regular inflation and deflation of the air cells within the cushion. Alternating high and low pressures inside the cells enable sequential off-loading, thereby facilitating reperfusion which is not dependent upon conscious intervention.


Sidhil’s Apollo and Artemis dynamic cushion systems represent the latest generation of dynamic seating technology. Designed to support 24 hour care, they can operate from the same pump as their matching dynamic therapy mattress systems, ensuring that patients are fully supported and protected against tissue damage. With a 10 minute cycle time and facilities including low pressure alarms, these cushions have a pressure adjustment system capable of handling users weighing up to 190kg (30 stone).

home environments, with a maximum user weight of 107kg (17 stone). These systems are also suitable for use in combination with existing Sidhil mattress pumps, saving money and space. The Serenade Lite dynamic cushion is a stand alone system with a smaller pump unit, ideal for community and nursing home environments.

Static seat cushions

Static cushions designed using foam and gel work to achieve a constant pressure at the interface between seat and user which is sufficiently low to allow perfusion within both deep and superficial tissues, avoiding tissue damage and reducing the prevalence of pressure ulcers.

Foam cushions vary by density, with high density foams offering higher levels of durability. These seating options benefit from being relatively inexpensive and easy to use, providing a stable support surface as well as the ability to warm up quickly and retain heat.

Sidhil’s Serenade Gel range incorporates a silicone gel flotation system which significantly reduces pressure and provides optimum comfort and stability for patient safety. The range includes a bariatric version to accommodate heavier patients weighing up to 320kgs (50 stone), as well as a Value option combining high density foam and silicon flotation.

The Serenade range includes the Serenade VE with two grades of pressure reducing visco elastic foam and a bariatric version for patients weighing up to 320kgs (50 stone). Sidhil’s affordable Value range includes the Value Pro combining two grades of pressure reducing foam and the Value Seat high density foam cushion. All feature two way stretch vapour permeable PU covers for hygiene and practicality.

Used correctly, both static and dynamic systems have a vital role to play in preventing pressure ulcer development, enabling individuals to achieve optimal mobility function and quality of life.
