Duke Extra 2.0 Active Mattress - Bariatric-Grade Pressure Relief for Very High-Risk Patients.
- 29-Cell Edge-to-Edge Coverage for Bariatric Stage 4 Care - the Duke Extra 2.0 provides 25 alternating air cells and 4 static pillow cells across a 2000 x 1200 x 200mm profile, delivering edge-to-edge pressure redistribution across the full width of the 1200mm mattress surface for bariatric residents at very high risk or managing existing stage 4 pressure injuries; the higher cell count compared to the Hampton Extra provides more granular pressure offloading across the wider surface area, addressing the elevated stage 4 pressure care requirement in bariatric residents.
- Electronic Pressure Control for Consistent Therapy - the Duke Extra 2.0 includes electronic pressure control that adjusts and maintains optimal cell inflation pressure based on the patient's weight and position, compensating for bariatric load variation during repositioning and sleep movement; consistent pressure maintenance across the 29-cell array is critical in stage 4 care where any period of above-threshold interface pressure can arrest wound healing; the electronic control system also provides operational monitoring for care staff responsible for overnight therapy continuity.
- CPR Valve for Emergency Deflation - the built-in CPR valve enables immediate full deflation of the mattress surface in a cardiac arrest scenario, providing rapid access to a firm resuscitation surface without mattress removal; in bariatric care, the additional weight and depth of the mattress system makes physical removal of the mattress during resuscitation impractical, making the CPR valve a critical safety feature that must be tested and confirmed operational at each deployment with documentation retained.
- Harvest 3 Pump Only - 317kg SWL - 3-Year Warranty - the Duke Extra 2.0 requires the Harvest 3 pump exclusively to maintain the pressure and airflow required for correct operation of the 1200mm cell array at bariatric loads; SWL is 317kg (50 stone), covering the full bariatric weight range for which 1200mm profiling beds are indicated; fits Community 1200 and Ultimate 1200 beds; all cells individually replaceable; full bed rail compliance; 3-year warranty included.
Duke Extra 2.0 Active Mattress - 29 Cells - 1200mm Bariatric - 317kg SWL - Stage 4 Capable
The Duke Extra 2.0 Active Mattress from Harvest Healthcare is a 29-cell bariatric alternating pressure replacement mattress providing edge-to-edge coverage for residents at very high risk of pressure ulceration or those with existing stage 4 injuries requiring 1200mm profiling beds. The 25 alternating air cells and 4 static pillow cells deliver intensive pressure redistribution with electronic pressure control for consistent bariatric load management. CPR valve provides immediate emergency deflation. Compatible with Harvest 3 pump only. SWL 317kg. Fits Community 1200 and Ultimate 1200 beds. Full bed rail compliance. 3-year warranty.

Regulatory Compliance
The Duke Extra 2.0 is a Class IIa active medical device under Medical Devices Regulation 2017/745. Clinical selection requires validated pressure risk assessment per NICE CG179 confirming very high-risk status or existing stage 4 injury in a bariatric resident requiring 1200mm bed configuration. SWL must be verified and documented before deployment per MHOR 1992. The Harvest 3 pump must be confirmed available and dedicated to this system; no alternative pump may be used. CPR valve must be tested operational at each deployment. Bed frame must be confirmed as Community 1200 or Ultimate 1200. Crib 5 cover meets BS 5852 requirements. Equipment register records and MDR conformity documentation must be maintained for CQC Regulation 12 readiness.
Frequently Asked Questions
How does the Duke Extra 2.0 compare to the Hampton Extra for bariatric stage 4 pressure care?
Both the Hampton Extra and Duke Extra 2.0 are 1200mm wide Harvest Healthcare bariatric mattresses for very high-risk and stage 4 care, both requiring the Harvest 3 pump and supporting 317kg SWL. The clinical differentiator is cell count and pressure management sophistication. The Hampton Extra has 18 cells (17 alternating, 1 pillow) with standard pressure control, while the Duke Extra 2.0 has 29 cells (25 alternating, 4 pillow) with electronic pressure control that actively adjusts to patient weight and position. The higher cell count of the Duke Extra 2.0 means each anatomical zone is offloaded more frequently within the alternating cycle, providing more intensive pressure redistribution across the 1200mm surface, which is the clinically appropriate choice for stage 4 wound management. The electronic pressure control also compensates for the load variation that occurs as a bariatric resident shifts position during sleep, maintaining consistent cell pressure that a standard pump cannot achieve. For very high-risk residents without existing stage 4 wounds, the Hampton Extra may be clinically sufficient; for those managing active stage 4 injuries, the Duke Extra 2.0 is the more clinically appropriate selection.
What does edge-to-edge coverage mean in the context of a 1200mm bariatric mattress?
Edge-to-edge coverage means that the active alternating cell array extends across the full width of the 1200mm mattress surface without a passive border zone at the lateral edges. In a bariatric resident using a 1200mm mattress, the body contact footprint is significantly wider than in a standard-weight resident, meaning the lateral body surfaces - hips, thighs, and upper arms - may be in contact with the mattress at or near the edge during lateral positioning. If the cell array does not extend to the mattress edge, the lateral body surfaces at the edge zone would rest on a static foam or passive border that provides no active pressure redistribution, concentrating load at exactly those peripheral sites. The 25-cell arrangement of the Duke Extra 2.0 is distributed to provide active alternating coverage across the full 1200mm width, preventing the creation of high-pressure peripheral zones at the lateral mattress edges during lateral repositioning and sleep.
