Viscoflex Plus Cushion - High-Density Viscoelastic Foam Cushion for Optimal Pressure Relief.
- Injected Foam with Skin-Effect Moulded Construction - the Viscoflex Plus uses an injected high-density viscoelastic foam manufacturing process that produces a single-piece moulded foam body with a denser outer skin and a softer internal core; the skin-effect construction prevents the foam from crumbling, tearing, or delaminating at the surface over time, which is a failure mode of cut-foam cushions where the surface cells are exposed and vulnerable; the injected manufacturing process also produces more consistent density distribution throughout the foam than cutting, improving pressure redistribution uniformity across the seated contact area.
- Ergonomically Shaped Load-Bearing Core for Sacral and Ischial Support - the ergonomic load-bearing core within the injected foam body is shaped to provide optimal immersion at the ischial tuberosities and sacral zone, where seated pressure injury risk is concentrated; the shaped core positions the highest visco foam compliance at the correct anatomical sites, increasing the contact area at the ischial zone and reducing peak interface pressure, while the outer foam layer provides stability and increases the total contact area to distribute load across the seated surface.
- Pommel Option for Additional Postural Stability - the Viscoflex Plus is available with a pommel - a raised foam feature at the front centre of the cushion between the thighs - that provides additional seated postural stability for residents at risk of forward sliding or abduction in the seat; the pommel is clinically indicated where the resident's muscle tone, spasticity, or pelvic control creates an elevated risk of unstable seated posture that standard cushion geometry cannot adequately address; pommel use requires occupational therapist assessment and documentation.
- Three Sizes - SWL up to 150kg - High-Very High Risk - MDR Class IIa - P361CA42421HF (420x420x80mm, SWL 100kg); P361CA45421HF (420x450x80mm, SWL 110kg); P361CA51461HF (460x510x80mm, SWL 150kg); welded VP water-resistant 4-way stretch cover; pairs with Viscoflex Multi-bearing mattress; high-to-very-high risk per NICE CG179; MDR 2017/745 Class I medical device; SWL verified per MHOR 1992.

Regulatory Compliance
The Viscoflex Plus Cushion is a Class I medical device under MDR 2017/745. Clinical selection requires occupational therapist assessment confirming high-to-very-high risk seating need per NICE CG179. SWL must be verified against the resident's documented weight per MHOR 1992. Where the pommel option is prescribed, the occupational therapist must document the clinical rationale and confirm the pommel does not impair safe transfer from the seat. Equipment register records and MDR conformity documentation must be maintained for CQC Regulation 12 compliance.
Frequently Asked Questions
What is injected foam and how does the manufacturing process affect clinical performance?
Injected foam is produced by injecting the foam precursor chemicals into a closed mould rather than by cutting sheets of pre-made foam block to the required shape and profile. The injection process allows the foam density, pore structure, and shape to be controlled precisely within the mould, producing a cushion body where the internal core density, the ergonomic shape, and the outer skin surface are all formed as a single integrated piece rather than assembled from separate components. The skin-effect outer layer is formed naturally during the moulding process as the foam reacts against the mould surface, producing a continuous, denser skin that is more resistant to abrasion, tearing, and surface cell breakdown than the cut surface of a block-foam cushion. In clinical terms, this means the Viscoflex Plus maintains its pressure redistribution performance and surface integrity over a longer service life than cut-foam equivalents, with the ergonomic core profile retained accurately rather than being susceptible to the tolerances introduced by mechanical cutting.
When is the pommel option clinically indicated, and what are the contraindications for its use?
A pommel is a raised forward projection from the front of the cushion seat surface, positioned between the user's thighs, that provides a physical barrier to prevent the resident from sliding forward or the legs from abducting outward. It is clinically indicated for residents with significant lower limb spasticity that causes involuntary abduction, for those with very limited pelvic and core muscle control who tend to slide into sacral sitting despite a standard pre-ischial ridge, and for those whose postural assessment identifies a specific need for medial thigh support that standard cushion geometry cannot address. Contraindications include: residents who use the cushion surface for assisted transfers where a pommel would obstruct the transfer path; residents with hip replacement where abduction restrictions make a fixed medial barrier a risk; and residents who may become distressed or agitated by a physical constraint at the anterior thigh. The pommel must never be used without documented occupational therapist assessment of the clinical indication and documented exclusion of each contraindication, as inappropriate pommel use may be considered a physical restraint under the Mental Capacity Act 2005.
