Description

Indulge in the serenity of Osaki's most elegantly crafted dual back massage rolling system. With a gentle touch of a button, the sliding doors on either side open effortlessly, inviting you to sink into a world of relaxation. Allow the AI system to analyze your body and choose the most effective massage from 41 preset programs, ensuring maximum results. Experience this transformative journey, all within the intimate comfort of your home or office.

Ai Series Technology - The Osaki Grand Duo gently cares for your well-being with its built-in A.I. health sensor, reading the tension hidden in your back with delicate precision through the sensor located at the front of the armrest. As the chair collects data from the finger sensor, it will select the most effective massage from 41 preset programs, focusing on key areas that require special attention. Every touch is thoughtfully geared to melt away your tension, offering a tailored experience of pure relaxation.

Body Scan Technology - The Osaki Grand Duo carefully traces the unique contours of your back with its smart body scan, ensuring every curve receives the perfect amount of pressure—from the neck down to the glutes. No area is left untouched, as the chair’s careful attention wraps you in complete, soothing care, ensuring every moment is designed to deliver the most effective massage to body.

FAQ

How long will delivery take?

Free curbside delivery averages 7–10 days; white glove delivery (room-of-choice placement) averages 10–16 days. You'll be contacted to schedule white glove delivery.

What warranty is included?

Our massage chairs include a 3-year manufacturer's parts & labor warranty. See the Warranty tab above for full terms.

Can I pay in installments?

Yes — Shop Pay Installments is available at checkout, with monthly payment plans shown under the price.

What if I need help choosing?

Call us at +1 309-761-5778 and speak with a product expert — we'll help you find the right fit for your needs and space.

What's the difference between 3D, 4D, and 5D massage?

3D rollers move up and down, side to side, and in and out to adjust massage depth. 4D adds variable speed and rhythm on top of that, mimicking human hands more closely. 5D refines this further with AI-driven precision for the most lifelike massage. Higher numbers generally mean a more nuanced, customizable massage — see the comparison table above for which models offer what.

How much room do I need for a massage chair?

It depends on the model — check the Specifications tab for exact upright and reclined dimensions. Most of our chairs need between 1 and 8 inches of wall clearance to fully recline (see the comparison table above). Allow a few extra inches around the chair for comfortable entry and exit.

Do massage chairs require assembly?

Chairs arrive mostly assembled. With white glove delivery, the delivery team places the chair in your room of choice and handles setup. With curbside delivery, final placement is up to you.

How do I choose the right model?

Start with your budget, then consider must-have features like heating zones, voice control, and body scanning. The comparison table above shows our four most popular models side by side. Still unsure? Call us at +1 309-761-5778 and a product expert will help you find the right fit.
