ObboMed OB-3650 UltraAir Alternating Pressure Mattress with 23 LPM Low Air Loss, 15°/25°/40° Rotation, Massager & Warmer, Easy Go In-Bed Care and Inflatable Guardrails
Bed Frame, Bedpan and Shampoo Basin are not included!
The ObboMed OB-3650 UltraAir is made for anyone who spends long hours in bed and needs dependable protection against pressure ulcers. Its alternating pressure system keeps moving the body's pressure points, improving circulation and helping prevent painful bedsores. It is a strong choice for seniors, post-surgery recovery, people with limited mobility and long-term home care.
Low Air Loss technology sends gentle airflow across the skin to keep it dry, cool and comfortable, cutting down moisture, irritation and the risk of skin breakdown. Because the mattress shifts pressure automatically, it also reduces the need for frequent manual repositioning, making home care smoother, safer and far less tiring for caregivers. On top of this, the OB-3650 adds 15°/25°/40° rotation, one-touch Easy Go toileting and hair-washing, inflatable guardrails, a vibration massager and a body warmer. Also available as a Low dB model, in a 42" x 80" size (OB-3650B) and a customized 42" x 84" size (OB-3650B4).
Triple Pressure Relief Therapy
Advanced Alternating Pressure: Air cells inflate and deflate in cycles of 10, 20, 30 or 40 minutes, so pressure never rests on one area for long. This boosts blood flow and greatly lowers the risk of pressure sores for bedridden or immobile patients. Choose the cycle time that best suits comfort and therapy needs.
Dynamic Low Air Loss:23 LPM of low air loss, boosted by an 820L air flow fan, removes heat and moisture from beneath the body to keep the skin cool and dry.
Multiple Rotation Angles: The 15° setting gives gentle, continuous movement, while 25° and 40° allow deeper repositioning and support lung function.
Toileting: With a single touch, four air cells beneath the buttocks deflate in about 20 seconds, forming a recessed opening for a bedpan. In-bed toileting spares the patient an uncomfortable transfer and lightens the caregiver's workload, improving both safety and hygiene.
Hair-Washing: One touch gently deflates the head section in about 20 seconds to make room for a shampoo basin, so hair can be washed without moving the patient.
Press again and the mattress restores its full support surface. (Bedpan and shampoo basin are sold separately.)
Cell-on-Cell Design with 24-Hour Power Outage Protection
The cell-on-cell structure keeps the patient from bottoming out for up to 24 hours during a power outage. When power fails, the system sounds an audio and visual alarm and the bottom layer stays inflated, as long as the air hose remains connected to the control unit. The easy-to-use control unit mounts on the bed's footboard and manages every function.
Patented Inflatable Guardrails
Soft yet firm 4-inch air-filled guardrails replace hard metal side rails. They help prevent falls without the bruising risk of metal rails, and a mid-section opening lets the patient get in and out safely. The rails deflate within seconds using the quick-release valve (manual) and re-inflate just as quickly, making them ideal for long-term care and home health settings.
Low Air Loss (LAL) Feature Built-in Air Flow Fan
Positioned beneath the cover layer, the Comfort-Focused LAL system delivers 23 liters per minute of airflow, combined with a built-in 820L air flow fan. It removes humidity and controls moisture and heat around the patient's skin, keeping the surface dry and comfortable. This extra skin protection is especially important for people of all ages living with stage 1 to stage 4 pressure ulcers.
Multiple Rotation Angles (15°/25°/40°):
To suit different patient needs, the mattress offers 15° self-rotation, 25° Right, 25° Left, 25° Auto Rotation and 40° Auto Rotation. These modes increase patient activity, assist lung function by helping clear phlegm, reduce the risk of pulmonary infections and support better therapy outcomes.
15° Self-Lateral Rotation:
Specialized air cells continuously inflate and deflate to create a gentle 15° wave-like motion. This shifts the user's weight, relieves pressure points, stimulates circulation, improves sleep and helps prevent bedsores.
Sinking Feature with Centralization:
The mattress surface lowers by up to 4 inches, and together with the patented 4-inch guardrails it forms an 8-inch deep soft barrier. This keeps the patient centered during alternating pressure and rotation, even during 40° rotations, while still giving caregivers easy access.
Vibration Massager + Body Warmer
Vibration Massager: Four built-in vibration massagers, run by a microprocessor with multiple massage modes, help loosen chest congestion and clear phlegm. They also ease tension and pain, promote circulation and support respiratory health, which is valuable for patients with limited mobility or chronic lung conditions.
Body Warmer: A built-in warming system sits directly above the alternating air cells and spreads gentle heat along the patient's back. The warmth encourages blood flow and relaxation, which is especially helpful for those at risk of pressure ulcers or with poor circulation.
Fowler & Sitting-up Function
When the head of the bed is raised, the Fowler function adds support in the seat and torso sections so the patient does not "bottom out." This keeps support consistent and lowers the risk of pressure injuries while sitting up.
Why It's Worth Having
Helps prevent pressure ulcers by constantly redistributing pressure
Improves blood circulation to support skin health and recovery
Keeps the skin cool and dry with Low Air Loss airflow
Reduces discomfort during long hours of bed rest
Supports healing for those who already have early-stage pressure sores
Why You Need It
You or a loved one spends many hours lying down every day
Repositioning in bed is difficult or painful
You want a safer, more comfortable recovery after surgery or illness
You want to reduce the risk of complications, infections and skin damage
You want peace of mind that professional-level care is provided at home

IBIS Wheelchair to Car Lift
The IBIS wheelchair to car lift was a game changer for us. My husband has been in a wheelchair for more than 40 years and we have never seen anything like this in the US and had no idea such a lift exist existed.
My guy is hemiplegic and usually able to stand pivot into the car but he broke his femur in November 2025 and had to be non-weight bearing for 3 months. He lost so much strength and ability that he could no longer do any kind of safe transfer.
Our friend found the IBIS wheelchair to car lift online and we decided to take the risk. It was worth every penny and more. Within a day of its arrival we were mobile and in and out of the car again. It is very manageable for me to operate and in our 60’s we are grateful for anything that lightens our load.
Everything arrived as advertised. Customer service was outstanding with clear communication. I was provided help to ensure my measurements were correct and was offered a few options to customize the sling. We had to get a new car right after we bought the lift and it was a good fit in the new car.
We are very pleased and highly recommend this product.

I love the fact it installs along the side and does not have a huge footprint. It works great lifting scooter or wheel chair. Easy to use.

Fantastic Experience from Mediriser
Fantastic experience with Mediriser! We purchased a red light therapy bed and an HBOT machine. The customer service team was incredibly responsive throughout the entire process. Even when we hit a few unexpected bumps, they completely took ownership and went above and beyond to resolve them. Highly recommended for wellness equipment!
