Shipping & Delivery

All of our items have a FREE SHIPPING OPTION within the contiguous United States, we do also offer a $300 shipping fee for Hawaii and Alaska.

At Massage Chair Warehouse, we prioritize efficient and timely shipping for all your orders. Our goal is to deliver your items as quickly as possible, often surpassing our own target of 5 business days from the order date. We are committed to exceeding your shipping expectations.

To keep you well-informed during the shipping process, we will promptly provide you with tracking information. Within 24 hours of your order leaving our warehouse, you will receive an email with the tracking details. This allows you to easily monitor the progress of your package and anticipate its arrival.

If, by any chance, you haven't received tracking information within six business days of placing your order, please don't hesitate to contact us. Reach out to our dedicated team at hello@massagechairwarehouse.com or give us a call at (704) 486-2384, and we will be happy to assist you.

Shipping:

At Massage Chair Warehouse, we offer two shipping options for your convenience. If you choose our free shipping option, you can expect to receive your item curbside within 7-10 business days from the shipment date, often even sooner. Our reliable carriers will bring your chair to your front door in separate boxes, with the chair itself in one box, the armrests in another, and the footrest in the last box.

Assembly is straightforward, typically involving attaching the armrests, footrest, and occasionally a pedestal for your remote. We provide installation videos on our website and YouTube channel to assist you. Please note that our chairs are heavy, so it's advisable to have assistance when moving the chair within your home.

To ease chair movement, using a dolly or two is recommended. Simply fully recline the chair, place the dolly next to it, and "tip" the chair onto its side onto the dolly. This allows for easy rolling to your desired location.

Alternatively, we offer a white glove delivery service. With white glove delivery, our professional team will bring the chair to your home, place it in your chosen room, and handle the setup. They will also remove all packaging debris, leaving your space clean.

Please note that with white glove delivery, your chair will be transported via LTL Freight before being transferred to the final mile/white glove delivery company, extending the delivery time by approximately one week.

When scheduling white glove delivery, it's important to inform the company of any stairs or challenging locations in your home. If you anticipate difficulties, please share pictures with us for proper preparation.

If a third person is required for delivery, additional charges may apply. We advise carefully considering whether white glove delivery is necessary before placing your order to avoid surprises.

In the case of returns or exchanges, white glove pickup will be necessary, incurring additional costs. Please keep this in mind, as the delivery company will handle the removal of packaging debris.

At Massage Chair Warehouse, we prioritize customer satisfaction and strive to deliver your order in perfect condition. Before signing the shipping weigh bill, we kindly request that you thoroughly inspect your item. By accepting a damaged product, you release the shipping company and us from liability. Once you accept the shipment as non-damaged, the item becomes your responsibility.

If you notice any damage upon delivery, please contact us immediately at (704) 486-2384. Our team will promptly engage with the manufacturer while the Shipping Agent is present to resolve any concerns you may have.

Overview

Osaki Grand Duo 4D+4D Two independent 4D mechanisms working at the same time.

The Grand Duo runs two independent 4D roller mechanisms at once. One works the neck and back while the second works the glutes and hamstrings, so the upper and lower body are massaged in the same pass instead of waiting for a single roller set to travel the length of the frame. Both ride a 53-inch SL-Track that follows the spine and continues under the seat.

Osaki backs the rollers with 62 air cells. The armrest airbags are split into three segments, the calf rest holds 8 airbags and 2 rollers, and the footrest pairs 4 foot rollers with 16 airbags.

Getting in works differently from most chairs. A side panel slides back at the press of a button, so you step into the seat instead of climbing over a fixed armrest. A biometric sensor in the armrest takes a fingertip reading, and the chair uses it to recommend one of 41 automatic programs. Five manual programs cover sessions you want to set yourself.

The chair weighs 332.3 lb and measures 65.7 inches long, 33.5 inches wide and 48.5 inches high upright. It needs 1 inch of wall clearance to recline fully. An 8-inch wireless touchscreen, a side control panel and voice control run it, and Bluetooth audio, LED lighting, a negative ionizer, aromatherapy and a wireless charging pad complete the cabin.


Construction

What the Grand Duo is built around.

01Dual 4D Mechanisms for Upper and Lower Body

Two separate 4D roller systems run simultaneously. 4D adds adjustable speed and rhythm to the depth control of a 3D roller, and having a second 4D set below means the glutes and hamstrings are worked while the back program continues, not after it.

0253-Inch SL-Track

The track curves with the spine and then extends under the seat in an L. At 53 inches it carries the rollers from the neck past the glutes to the top of the hamstrings, the reach the lower mechanism needs to do its job.

0362-Cell Air System with 3-Segment Armrests

Sixty-two air cells cover the shoulders, arms, seat, calves and feet. The armrest airbags inflate in three segments along the forearm and hand, pressing in sequence rather than as one block of air.

04Calf Rollers and a 16-Airbag Footrest

The calf rest combines 8 airbags with 2 rollers, and the footrest adds 4 foot rollers and 16 airbags. The footrest extends automatically by up to 7 inches to meet longer legs.

05Button-Operated Sliding Side Panel

A panel slides back to open the side of the seat. For anyone who finds stepping over a fixed armrest awkward, this is what makes a large dual-mechanism chair practical to use every day.

06Armrest Sensor and 41 Automatic Programs

Rest a fingertip on the armrest sensor and the chair recommends a program from its 41 presets based on the reading. You can skip the sensor and choose a program, or one of 5 manual programs, from the 8-inch wireless touchscreen.


Buyer's Guide

Choosing between Osaki's dual-mechanism chairs.

A dual-mechanism chair splits the work between two roller sets, so the useful question is what the second set can do. In the Grand Duo both mechanisms are 4D. In Osaki's Manhattan Duo and 4D Orion Duo Mech the lower mechanism is 3D, which controls depth but not the speed and rhythm changes of a 4D roller.

Air coverage is the next difference. The Grand Duo carries 62 air cells, 16 of them in the footrest alone, against 26 in the Manhattan Duo. The program library follows the same pattern: 41 automatic and 5 manual programs on the Grand Duo, 16 automatic and 7 manual on the Manhattan Duo.

Size is the trade-off. The Grand Duo is 33.5 inches wide and weighs 332.3 lb, against 31.5 inches and 273.2 lb for the Manhattan Duo. Measure doorways and hallways against that 33.5-inch width before delivery, and plan for two boxes of 340.6 lb and 56 lb.

Placement is easier than the footprint suggests. The Grand Duo needs only 1 inch between the backrest and the wall to recline fully, and in full recline it grows to just 70.9 inches long while dropping to 34.6 inches high, so it fits a room where a standard recliner would need a clear gap behind it.

FAQ

Questions buyers ask about the Grand Duo.

How do the two mechanisms divide the work?

Each is a separate 4D roller system. One covers the neck and back, the other the glutes and hamstrings, and both run at the same time along a 53-inch SL-Track.

How close to the wall can it sit?

1 inch. At full recline the chair is 70.9 inches long and 34.6 inches high.

What does the armrest sensor do?

It takes a fingertip reading, and the chair uses that reading to recommend one of its 41 automatic programs. You can also choose any program or one of the 5 manual programs yourself.

How do I get into the chair?

Press the button and the side panel slides back, opening the seat from the side so you do not have to step over a fixed armrest.

Where does the chair heat?

The back and chest, the calves and the feet.

What warranty does Osaki list?

Osaki lists the Grand Duo with a 5-year warranty: three years of full service, followed by two additional years of parts coverage.
