Osaki Ai 4D Yoga Flex Massage Chair

Most massage chairs leave the lower body to the air cells. The Yoga Flex adds an independent leg massager with a scissor-action mechanism that mimics walking, pulling and extending the legs to stretch the lower back, glutes, hamstrings, and knees - the part of recovery a standard chair skips entirely.

Taupe

On top of the walking system sits a true 4D flex mechanism that moves up, down, side to side, and in and out, changing speed and depth in real time along an SL-Track that guides the rollers from the neck and shoulders down to the hamstrings in one continuous pass. Osaki's AI Health Detection reads your body's tension patterns and tunes the massage to what you're carrying that day, while an automatic body scan runs every time the chair powers on, mapping your shape so the rollers fit you instead of an average build. Three stages of zero gravity recline tilt you progressively further back, spreading body weight evenly and relieving pressure points along the way.

Thirty-four air cells deliver targeted compression to move blood and ease tension throughout the body, paired with lumbar and calf heating to loosen muscle before the compression goes to work. A vibrating seat adds coverage most chairs skip - the hips and thighs - while an automatic footrest extends to fit a range of heights. Choose from 16 auto programs and 7 manual massage styles on the touchscreen remote, and finish with ambient LED lighting, all in a space-saving frame that fully reclines with just 5 inches of wall clearance.

AI Health
Detection

Sensors read your muscle tension patterns and pressure sensitivity before each session, adapting the chair's technique and intensity to what your body actually needs that day.

Walking
Technology

Unlike standard massage chairs that neglect the lower body, the Osaki Yoga Flex 4D provides balanced care with a unique scissor-action mechanism that simulates natural walking. This gentle motion stretches the lower back, glutes, hamstrings, and knees—delivering a truly full-body wellness experience.

Combines the spinal-curve following of an S-track with the extended reach of an L-track, carrying the rollers from your neck all the way through your glutes and into your hamstrings in one continuous pass.

Massage

Targeted vibration works the pelvic region, hips, and glutes - areas most massage chairs overlook entirely - loosening tight muscles and reducing stiffness for those who sit for long stretches.

Three progressive stages elevate your legs above heart level and distribute body weight evenly, reducing spinal pressure while the rollers work most effectively.

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.

It works very well

Annetta Voigt

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!

Chris Brotzman

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.
