The Melissa Heavy is a bariatric medical mattress that combines structural stability with a documented low interface pressure. Featuring a maximum weight capacity of up to 300 kg, it provides safety and reassurance for both patients and healthcare professionals, while supporting the prevention and therapeutic management of pressure ulcers up to and including Category 3.
The foam core consists of two layers of carefully selected foam types. Together with our RX cover, this provides the conditions for excellent pressure distribution. With a proven low pressure on protruding body parts, such as heels and shoulders, no separate heel zone is required.
The mattress has successfully completed fatigue testing in accordance with standard SS 876 00 11. It is therefore verified to maintain its clinical performance and structural integrity during articulated seating positions with an elevated backrest.
Melissa Heavy comes with a cover.
All covers feature an integrated protective zip flap.
Can be supplied with welded seams (-W)
STANDARD FOR OBJECTIVE EVALUATION
To obtain an objective assessment of mattresses' pressure distribution properties, RISE[1] developed a measurement method where the actual counter-pressure exerted by a mattress is measured using indenters. The measurement method is described in Swedish standard SS 876 00 13.
Melissa Heavy have been tested by RISE[1] according to measurement method SS 876 00 13 and is pressure-distributing up to wound category 3.

FAQ
The mattress is constructed with an 18 cm thick core where a robust base of high-resilience cold foam interacts with an upper layer of viscoelastic foam. This construction effectively distributes pressure even under maximum load.
Yes, independent pressure tests show that Melissa Heavy maintains its excellent pressure-relieving properties even for lower-weight users, making it a versatile solution on the ward.
Yes, the mattress has undergone fatigue tests according to SS 876 00 11 with good results and offers a stable seating function when the backrest is raised.
We recommend the RXH-5 cover, which is equipped with sturdy handles, making it easier to handle and move the mattress without the patient.
