The Rhythm Multi Plus Mattress System is an advanced pressure redistribution mattress replacement designed for patients considered at medium to high risk of developing pressure injuries. It may also be incorporated into a clinician-directed pressure management plan for patients with existing Stage 1, 2, 3, or 4 pressure injuries, in accordance with facility protocols and professional clinical judgment.
Combining true low air loss, pulsation, 3-to-1 alternating pressure, and static therapy in one system, the Rhythm Multi Plus allows caregivers to select an appropriate support mode based on the patient’s individual needs. Constant low-pressure support redistributes weight across a broader surface area than a conventional mattress, helping reduce concentrated pressure during extended bed rest.
A 2-inch convoluted foam base provides an additional layer of support, including during a power interruption. Durable nylon polyurethane air cells have an easy-clean surface that supports routine care and facility infection-control procedures.
For focused heel protection, the Happy Heel feature provides three selectable softness settings across the final four air cells. This allows caregivers to adjust support around fragile heels as part of an individualized pressure management program.
Available in standard and bariatric widths, the Rhythm Multi Plus accommodates users weighing up to 1,000 lbs., depending on the selected mattress size.
The Rhythm Multi Plus Is Ideal For:
✔ Medium- to high-risk pressure injury prevention programs
✔ Existing Stage 1–4 pressure injuries
✔ Extended bed rest
✔ Limited mobility
✔ Pressure redistribution
✔ Heel offloading and protection
✔ Bariatric patient care
✔ Hospitals and rehabilitation centers
✔ Skilled nursing facilities
✔ Long-term care environments
✔ Clinician-directed home healthcare

FAQs
Frequently Asked Questions
Tap a question below to view the answer.
What is the Rhythm Multi Plus Mattress System?
The Rhythm Multi Plus is a powered pressure redistribution mattress replacement that combines true low air loss, pulsation, 3-to-1 alternating pressure, and static therapy in one system.
Who is the Rhythm Multi Plus designed for?
It is designed for patients considered at medium to high risk of developing pressure injuries based on a qualified healthcare professional’s clinical assessment.
Can it be used for existing pressure injuries?
The Rhythm Multi Plus may be incorporated into a clinician-directed care plan for patients with existing Stage 1, 2, 3, or 4 pressure injuries. Use must follow the treating professional’s recommendations and the facility’s pressure management protocols.
Does this mattress treat pressure ulcers by itself?
No. A therapeutic support surface is one component of a comprehensive pressure injury management plan. Skin assessment, repositioning, nutrition, moisture management, wound care, and other prescribed interventions remain essential.
How does the mattress redistribute pressure?
Its air-cell system spreads the patient’s weight across a broader support surface, helping reduce concentrated pressure on vulnerable areas of the body.
What therapy modes are available?
- True low air loss
- Pulsation
- 3-to-1 alternating pressure
- Static therapy
What is true low air loss therapy?
True low air loss uses airflow at the support surface to assist with heat and moisture management while supporting pressure redistribution.
What is pulsation therapy?
Pulsation therapy creates gentle, repeated pressure changes in the mattress according to the selected system settings.
What does 3-to-1 alternating pressure mean?
The mattress changes pressure among groups of air cells, creating regular shifts in surface loading. Consult the operating manual for the exact cycle pattern and adjustment instructions.
What is static therapy?
Static mode maintains a stable support surface without the regular pressure changes used in alternating therapy.
What is the Happy Heel feature?
Happy Heel provides adjustable support in the final four air cells near the foot end of the mattress. Caregivers can select from three softness settings based on the patient’s heel-protection needs.
Does the mattress provide support during a power outage?
Yes. A 2-inch convoluted foam base provides an additional support layer during a power interruption. Follow the manufacturer’s instructions and the facility’s emergency protocol if power loss continues.
Is this a mattress overlay or a complete replacement?
The Rhythm Multi Plus is a mattress replacement system designed to take the place of a conventional bed mattress.
What material are the air cells made from?
The air cells are constructed from nylon polyurethane, providing a durable and easy-to-clean surface.
How should the mattress be cleaned?
Follow the manufacturer’s cleaning and disinfection instructions, including approved products, concentrations, contact times, and drying procedures. Do not use chemicals that could damage the air cells or cover.
What sizes are available?
- 36"W × 80"L × 8"H
- 42"W × 80"L × 8"H
- 48"W × 80"L × 8"H
What is the weight capacity of the 36-inch mattress?
The 36-inch model supports users weighing up to 500 lbs. (227 kg).
What is the weight capacity of the 42-inch mattress?
The 42-inch model supports users weighing up to 750 lbs. (340 kg).
What is the weight capacity of the 48-inch mattress?
The 48-inch bariatric model supports users weighing up to 1,000 lbs. (453 kg).
Can any mattress size be placed on any bed frame?
No. The selected mattress must match the bed frame’s deck dimensions and rated weight capacity. The combined weight of the user, mattress, accessories, and other equipment must remain within the bed’s safe working load.
Is the Rhythm Multi Plus suitable for bariatric care?
Yes. The 42- and 48-inch configurations provide expanded widths and higher weight capacities for bariatric care environments.
Can this mattress eliminate the need to reposition a patient?
No. Repositioning requirements should be determined by the patient’s clinical condition and individualized care plan. Do not discontinue scheduled repositioning unless directed by a qualified healthcare professional.
Can the mattress be used at home?
It may be appropriate for clinician-managed home healthcare when the bed frame, electrical supply, room environment, caregiver support, and treatment plan meet the manufacturer’s requirements.
Where is the Rhythm Multi Plus commonly used?
It may be used in hospitals, rehabilitation centers, skilled nursing facilities, long-term care environments, and appropriately supported home-care settings.
Who should select the therapy mode and settings?
A qualified healthcare professional should select and review therapy settings based on the patient’s weight, skin condition, mobility, pressure injury risk, comfort, and overall care plan.
What should be checked before use?
Confirm the correct mattress size, user weight capacity, bed-frame compatibility, power connection, hose placement, system operation, and prescribed therapy settings. Caregivers should also review the manufacturer’s instructions and alarms before placing the system into service.
