Prime Comfort Plus Visco Top Cushion - High-Risk Pressure Relief
- Dual Viscoelastic Layer Construction - the Prime Comfort Plus Visco Top Cushion places viscoelastic foam on both the top and the bottom of a firm foam core, creating a tri-layer construction where both the skin contact surface and the underside of the cushion provide conforming slow-return foam support; the upper visco layer provides immersion and envelopment at the seated skin interface for pressure redistribution, while the lower visco layer reduces energy transfer from the firm base to the upper foam layer during seated loading, maintaining a consistently conforming pressure redistribution profile across the full seated weight range up to 158kg.
- Welded Flap Water-Resistant Cover for Enhanced Seam Protection - the welded flap cover construction eliminates the exposed zip pull-tab of a standard zipped cover, replacing it with a welded edge that provides both improved seam strength and a cleaner appearance; the welded seam and flap design reduces the risk of the cover opening during use or during transfer manoeuvres, and the welded construction provides enhanced fluid resistance at the seam compared to a stitched or standard zip edge; the navy blue colour provides a consistent professional appearance across the Prime Comfort Plus range.
- Non-Slip Base - Pairs with Prime Comfort Plus Mattress - the non-slip base prevents cushion displacement during transfers and seated movement; the cushion pairs with the Prime Comfort Plus Static Mattress (NCL-HSMPRIM) for 24-hour pressure area care, matching the foam specification of the mattress to provide a coordinated high-risk pressure redistribution system across both the seated and lying positions; clinical selection of the complete 24-hour system should be documented in the resident's care plan with both products listed.
- 430x430x75mm - 158kg SWL - High Risk - MDR Class I - a single size (430 x 430 x 75mm) with a SWL of 158kg (25 stone) covering the standard to above-average weight range; SWL must be verified against the resident's documented weight per MHOR 1992 before clinical issue; MDR 2017/745 Class I medical device; selected following occupational therapist assessment per NICE CG179; the single-size format simplifies procurement and stock management compared to the multi-size Prime Comfort Visco Top range.
Prime Comfort Plus Visco Top Cushion - Dual Visco Layers - Welded Flap Cover - 158kg SWL - 430x430x75mm
The Prime Comfort Plus Visco Top Cushion uses a tri-layer construction with viscoelastic foam on both the top and bottom of a firm core, providing a consistently conforming pressure redistribution profile at both the skin contact surface and the base interface. The welded flap water-resistant cover provides enhanced seam strength and fluid resistance over a standard zipped cover. Non-slip base. SWL 158kg. 430 x 430 x 75mm. Pairs with Prime Comfort Plus mattress for 24-hour care. MDR 2017/745 Class I medical device.

Regulatory Compliance
The Prime Comfort Plus Visco Top Cushion is a Class I medical device under MDR 2017/745. Clinical selection requires occupational therapist assessment confirming high-risk seating need per NICE CG179. SWL must be verified against the resident's documented weight per MHOR 1992 before issue. Equipment register records including MDR conformity documentation must be maintained for CQC Regulation 12 compliance.
Frequently Asked Questions
What is the clinical benefit of having viscoelastic foam on both the top and bottom of the cushion?
In a standard visco-top cushion, the upper viscoelastic layer provides pressure redistribution at the skin interface while a rigid or semi-rigid base provides structural support. The firm base is clinically useful for postural stability but introduces a harder contact surface at the chair seat interface, which can create a step change in compliance at the cushion-to-seat-pan boundary when the cushion is slightly thinner than the seat pan depth or when the chair seat has surface irregularities. The lower viscoelastic layer in the Prime Comfort Plus Visco Top addresses this by introducing a conforming interface at the base of the cushion as well, allowing the cushion to adapt to minor surface variations in the chair seat pan while still providing overall structural support through the firm core. This can be particularly beneficial on older chair seats or on surfaces that are not perfectly flat, where a rigid-base cushion may rock slightly, creating intermittent pressure concentration points at the base-to-seat contact zones.
How does the Prime Comfort Plus Visco Top differ from the standard Prime Comfort Visco Top cushion?
The standard Prime Comfort Visco Top (ID 179) uses a 50mm viscoelastic top layer on a single high-resilience foam base, and is available in three sizes with SWLs from 127kg to 190kg. The Prime Comfort Plus Visco Top (this product) uses viscoelastic foam on both the top and the bottom of a firm core rather than just the top, providing the additional base-level compliance described above; it is available in a single size (430 x 430 x 75mm) with a 158kg SWL and pairs with the Prime Comfort Plus mattress rather than the standard Prime Comfort mattress. The appropriate selection depends on whether the dual visco construction is clinically indicated for the specific resident and chair configuration; for residents on a smooth, modern chair seat pan with no surface irregularity, the standard Visco Top may provide equivalent clinical performance at lower cost, while the Plus variant's dual layer adds value in more complex seating environments.
