Most massage chairs cramp tall, broad, or heavier users. The Duke XL is built around an oversized, reinforced-steel frame that supports users up to 400 lbs and heights up to 6'8", with an extended backrest, widened armrests, and roomy calf wells - the frame that fits when standard chairs leave your shoulders boxed in or your calves hanging off the end.
Its 4D mechanism is what separates it from a 3D chair: the rollers vary depth, rhythm, and speed in real time, so the massage adapts as it works instead of running a single fixed intensity, tracking the spine along an SL-Flex track that reaches from the neck and shoulders down through the upper glutes. An AI-powered Intelligent Health Detection system reads heart rate, heart rate variability, blood oxygen, microcirculation, and fatigue level, then tunes the session to what your body is actually carrying that day, while automatic body scan technology maps your unique contours so the rollers align to your spine rather than a generic average.
Lower-body recovery gets real attention here: 14 air cells and 4 calf bumpers work the calves together, three specialized foot rollers stimulate the soles with reflexology-style ridges, and a spring-loaded footrest extends up to 7 inches to fit taller frames. Layer in 48 total air cells for full-body compression, a heating shawl delivering targeted warmth (about 75–83°F) to the lumbar and feet, and a zero-gravity recline that lifts the legs above heart level to ease spinal pressure. Choose from 20 auto programs and 5 manual modes on the touchscreen controller, and finish with Bluetooth speakers, a USB-C charging port, LED ambient lighting, and convenient shortcut panels - all wrapped in a frame purpose-built, not just upscaled, for bigger and taller bodies.

Features
Size-Accommodating Chair
A reinforced steel frame supports users up to 400 lbs, with an extended backrest fitting heights up to 6'8" and widened armrests and calf wells for broader frames.
4D Massage Mechanism
Rollers vary depth, rhythm, and speed in real time, adapting the massage as it works instead of running one fixed intensity throughout.
Intelligent Health Detection
Reads heart rate, heart rate variability, blood oxygen, microcirculation, and fatigue level, then tunes the session to your body in the moment.
SL-Flex Track System
Holds a fixed angle to the backrest and follows the body from the neck and shoulders down to the upper glutes for a deeper stretch than a rigid track allows.
Deep Calf Massage

The best Company we have ever dealt with.
Had a small late shipping issue, but they completely made it right with us. Quality of products are amazingly strong and durable. We definitely will do business with them again.
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.
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!
I am an executive at a large technology company, and represent a major lifestyle society with over 400 members as its president. My passion is lifestyle, and I have spent considerable time and resources testing and reviewing a number of therapies from a large number of suppliers. Allow me to say that the experience I have had so far with this company and product has been beyond exceptional. First, the customer care I have received is second to none. The team has been highly responsive no matter the day and time, provided accurate and sincere information, and given me the feeling of being looked after. I have not experienced this level of customer care before, and I would like to highlight that it is exemplary and I am ultimately grateful for this. Secondly, the product is of high quality and works better than expected. I have become an avid fan of HBOT therapy since I have received your product and would wholeheartedly recommend this therapy and your company to anybody. Lastly, what your company is doing for people is exceptional as it enables the wider public to have a revolutionary therapy at a highly affordable rate at home. Thank you for your time, effort and contribution to society. Please continue this great mission! Best regards.
Clinical excellence in a home setting. The UltraCare XT handles everything my wife's complex care protocol requires. The range of adjustment is excellent and the motor system is quiet and smooth. Her nursing team commented that having proper clinical equipment at home has made a genuine difference in her care quality. Mediriser was professional throughout.
