Bariatric Mattress Sizes, Thickness and Weight Capacity
Sizes and Lengths
The first rule for upgrading from a standard hospital bed mattress to a bariatric one is matching the exact dimensions of the bed frame. Our bariatric hospital bed mattress options come in 42", 48", 54", and 60" widths, paired with standard 80" lengths or 84" extra-long configurations on select models like the Emerald and Medacure CZ.
Thickness
Profile thickness varies by therapeutic need. The Prius VLX has a 6.75" profile, the Protekt Supreme Support 7", the Protekt Aire 9900 8", and the Emerald, Medacure CZ, and Rhythm Turn systems 10".
Weight Capacity
Weight capacities on these heavy duty hospital bed mattresses leave a safe margin for heavy individuals, from 550 lbs on the Proex 48" up to 650 lbs (Medacure LAL), 660 lbs (Emerald and Protekt Aire 7000), 750 lbs (Protekt Aire 8000), 850 lbs (Rhythm Turn), and 1,000 lbs on both the Medacure CZ and Protekt Aire 9900. If you need a compatible reinforced frame, you can match these surfaces directly to our bariatric beds.
Bariatric Foam Mattresses for Baseline Support
Medacure Proex
A bariatric foam mattress provides a stable, quiet resting surface without relying on electricity or pumps. The Medacure Proex is available in 42" and 48" widths and uses high-density European foam backed by a robust 7-year warranty, with the 48-inch model rated for 550 lbs.
Prius VLX
For more targeted comfort, the Prius VLX offers a 6.75-inch profile in the same two widths. It features a visco-elastic top layer and zoned foam construction with a softer heel section for pressure relief. A breathable stretch polyurethane cover and an easy-to-clean vinyl base protect the foam core, all supported by a 2-year warranty. You can also browse our pressure relief mattresses for more pressure redistribution options.
Hybrid Air and Foam Surfaces
Self-Adjusting Air Cells
Patients who need dynamic pressure redistribution without the noise of an electric pump benefit most from a hybrid design. The Protekt Supreme Support is available in 48" and 54" widths and uses 10 interconnected air cells that automatically adjust to the patient's movements.
Cooling Top Layer and Optional Pump
This 7-inch thick mattress features a Visco Gel Polymer Technology (VGPT) top layer to actively dissipate heat. It works without electricity and is listed under HCPCS codes E0373/E0277, with an optional alternating pressure pump available if clinical needs change.
Bariatric Air Mattress and Low Air Loss Systems
When managing advanced pressure ulcers requires powered clinical intervention, a bariatric air mattress uses digital pumps to actively control the inflation of specialized air cells.
Protekt Aire 9900 and 8000
The Protekt Aire 9900 combines four therapies in one system: zoned pressure management, true low air loss, alternating pressure, and pulsation. It supports 1,000 lbs and spans widths from 42" to 60". It features an Auto Fowler function and a cell-on-cell design that prevents the patient from bottoming out during a power outage. The Protekt Aire 8000 is a more affordable alternative, supporting up to 750 lbs in widths up to 60".
Low Air Loss for Heat and Moisture
For patients who run hot or face severe moisture control issues, bariatric low air loss mattresses provide a continuous micro-climate of airflow. The Wellell Serene Air supports up to 926 lbs in 42" and 48" widths, while the Medacure LAL manages up to 650 lbs.
Medacure CZ and Emerald
If the care plan requires shifting the patient's weight on a timed cycle to prevent skin breakdown, the Medacure CZ supports 1,000 lbs across 20 alternating cells. It includes a whisper-quiet digital pump that caregivers can set by patient weight or firmness preference, and it comes in 80" or 84" lengths. Emerald also offers a 660 lb capacity system with a weight-adjustable digital pump, static mode for safe transfers, and optional raised air bolsters. The Protekt Aire 9900 and 7000, Emerald, Medacure CZ, and Prius air systems all carry a 2-year warranty. You can find more options in our bariatric alternating pressure mattresses collection.
Bariatric Lateral Rotation Mattresses
Caregivers managing patients with severe immobility or respiratory complications rely on rotation systems to automatically turn the patient from side to side.
Prius Rhythm Turn
The Prius Rhythm Turn provides customizable 20-degree or 40-degree lateral turning cycles for patients up to 850 lbs.
Prius DUET and Protekt Aire 7000
The Prius DUET expands on this by combining 40-degree rotation with alternating pressure and low air loss for patients up to 700 lbs. For a 660 lb capacity option, the Protekt Aire 7000 delivers rotation across 42" and 48" widths. You can explore more turning systems in our bariatric lateral rotation mattresses collection.

Frequently Asked Questions
What size mattress does a bariatric bed need?
The mattress must match the exact width of your bariatric bed frame to ensure patient safety and proper equipment function. Bariatric mattresses are available in 42", 48", 54", and 60" widths, with standard 80" lengths and 84" lengths on select models.
What kind of mattress should a 300 pound person use?
A 300-pound person needs a mattress whose weight capacity comfortably exceeds their actual weight, such as models rated from 550 lbs to 1,000 lbs. You can choose a high-density foam surface for stable, non-powered support, or a powered air system if the patient needs active pressure redistribution to prevent bedsores.
Does a heavier person need a firmer mattress?
Support and pressure relief matter more than rigid firmness. High-density bariatric foam mattresses provide stable structural support. If you choose an air system, advanced models like the Emerald and the Medacure CZ feature digital pumps that let caregivers set the pressure by the patient's weight or firmness preference.
