The Osaki OS-Pro 4D+4D DuoMax SE pairs a Duo Mech™ dual 4D massage mechanism with AI-powered health detection, an adjustable SL Flex Track, heated jade cores, 38 air cells, and zero-gravity recline - a luxury, full-body massage chair that reads your body and adapts the session to it.
At its core is the Duo Mech™ dual mechanism: an 8 roller-track system built around quad precision rollers that adjust depth and speed in real time, gentle enough to unwind after work and deep enough to recover after a hard one. Before it gets to work, the chair's Intelligent HealthPro system checks in with you, reading heart rate, blood oxygen, microcirculation, and a fatigue index to shape a session that fits how you actually feel. The SL Flex Track adjusts its angle relative to the backrest to hug the natural curve of your spine, carrying coverage from your neck and shoulders down to your hamstrings, while two heated jade cores glide along your body's contours to blend massage with therapeutic warmth, backed by dedicated lower-back heat therapy.
The legs and feet aren't an afterthought here: vertical calf rollers and airbag compression deliver a deep calf massage, two specialized foot rollers per foot work key acupressure points, and an automatic footrest extends up to 7.8" to fit your height. A network of 38 air cells adds rhythmic compression across the shoulders, arms, hips, calves, and feet, while a piano-key arm massager - a zone most chairs skip entirely - cradles your arms in a gentle, wave-like rhythm. Choose from 20 one-touch auto programs or 11 manual techniques, control everything hands-free with smart voice commands or the free Osaki DuoMax app, and settle in with wireless phone charging, a USB port, HD Bluetooth speakers, and negative oxygen ion therapy - all wrapped in a space-saving frame that fully reclines with just 5.5" of wall clearance.

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.
