ENVELOP
Welcome to Therapeutic Excellence!
Available exclusively at Fairburn Medical Products, Envelop is the platinum standard in pressure injury treatment and prevention. It outperforms every competitor in the industry in the envelopment and immersion category of therapy support surfaces, and with a fraction of the cost of leading competitors, is the ideal choice for all levels of care and facilities. Envelop’s superior performance and efficacy is back by independent S3I testing.
With the newest and most effective technology on the market, Envelop’s 3 innovative and advanced control systems bring you into a new era of advanced wound care with the highest percentage of patient immersion, accelerated healing rates, reduced readmissions, and unmatched pressure injury prevention.
Deep Fluid Envelopment Technology (DFET) mimics immersion in a fluid, enveloping patients in superior comfort and healing for optimal pressure redistribution to treat and prevent pressure injuries. Envelop’s IPS (Intelligent Pressure Sensing) technology uses sensors to monitor patient movements in real time, automatically regulating airflow and mattress pressure to sustain continuous envelopment and prevent pressure peaks and bottoming out during repositioning. The S.M.A.R.T. (Self-monitoring Automatic Air Regulating) technology utilizes microprocessors to automatically sense and adjust to the patient’s weight.
This trio of advanced technology, together with its one-touch operation, makes Envelop a truly self-automated, “hands-free” therapy support surface, simplifying use for caregivers and streamlining patient care to create the ideal, individualized immersion and envelopment environment for patients.
Supporting weights up to 1000 lbs (450 kg – Bariatric Envelop), the innovative Envelop mattress replacement system is the premier choice for high-risk patients in hospitals, nursing homes, and long-term and home care settings.

Envelop provides maximum “sinking-in” support (Immersion) with 79% body contact, in conjunction with the mattress’s ability to conform to the patient’s unique body shape (Envelopment). Higher immersion and envelopment percentages allow for greater body surface contact, which helps distribute the individual’s weight over a larger area to reduce concentrated pressure and the risk of pressure injuries.

UNMATCHED PERFORMANCE, PROVEN RESULTS
Envelop sets the industry benchmark with independent Support Surface Standard Initiative (S3I) testing based on the National Pressure Injury Advisory Panel (NPIAP) standards- the definitive clinical authority for pressure injury assessment, treatment, and prevention. Clinical tests reveal up to 79.3% average immersion, and independent interface pressure testing demonstrate an average sacral pressure of only 25.25 mmHg, far surpassing competitors in pressure ulcer prevention and treatment efficacy.
Its bariatric extensions and no-gap square air cells ensure maximum support for safe patient mobility, while features like instant CPR deflation and vapor-permeable Dartex covers enhance clinical versatility.
Validated for high-risk environments, Envelop facilitates optimal tissue redistribution, reduces noise for better rest, and delivers evidence-based results for preventing skin breakdown in bariatric and standard patients up to 1,000 pounds (450 kg). Envelop is the benchmark facilities choose for measurable healing and compliance.
the envelop advantage: 3 revolutionary synergistic control systems

At the core of Envelop’s excellence is the ingenious automatic Deep Fluid Envelopment Technology (DFET), inspired by the wisdom of Archimedes and bolstered by patented Self-Monitoring Automatic Air Regulating Technology (S.M.A.R.T) and Intelligent Pressure Sensing (IPS) technology. This true air immersion and envelopment mattress replacement system mimics the effect of immersing a patient in water, using square 8-inch air cells to maximize the surface support area and patented algorithms to equalize pressure across the skin, promoting blood circulation and tissue relief for stages I–IV pressure ulcers. Engineered for very high-risk patients (Waterlow score 20+), Envelop’s 21-cell design fits widths from 35.5 inches to 48 inches. It provides quiet operation, superior sleep quality, and promotes outcomes that outperform every traditional pressure relief system available.
HOW DOES DFET ACHIEVE envelopment?
ARCHIMEDES’ WISDOM IN MODERN HEALING
Archimedes, the pioneering Greek mathematician, physicist, and inventor, described a fundamental law of buoyancy now known as Archimedes’ principle. It states that a body immersed in a fluid, whether liquid or gas, is lifted by an upward force equal to the weight of the fluid it displaces. Drawing on this principle, Envelop uses air as the “fluid” to gently buoy the patient, helping to reduce and equalize pressure across the body for superior support and comfort.

INTELLIGENT ADAPTATION with s.m.a.r.t. and ips
Self-Monitoring Automatic Air Regulating Technology (S.M.A.R.T.) takes the helm in maintaining the ideal pressure, utilizing sophisticated algorithms and multiple sensors to automatically determine the patient load in real-time, turning the mattress into a direct sensor pad.
Complementing this, Intelligent Pressure Sensing (IPS) dynamically responds to movements, regulating airflow to maintain the ideal continuous immersion, envelopment and comfort, displaying pressure levels on an easy to read LCD display.
Envelop also features Fowler Boost for reclined positions, Max Inflate for nursing tasks, and up to 15-hour transport mode, ensuring uninterrupted care during power failures or mobility with built-in battery backup.

Envelop: Where innovation meets comfort
In the world of wound care, Envelop stands as a beacon of innovation. Set a new benchmark in wound care with the Carilex Envelop therapy mattress, a bariatric-ready support surface that combines Deep Fluid Envelopment Technology (DFET), S.M.A.R.T., and IPS to deliver exceptional immersion and envelopment for maximum pressure redistribution and patient comfort. Designed for very high-risk patients and pressure injury management, Envelop unites intelligent automation with a soothing sleep experience so that comfort, safety, and healing are always at the forefront of care.
