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 Manhattan Duo A 4D upper mechanism and a 3D lower mechanism in one frame.

The Manhattan Duo divides the massage between two mechanisms. A 4D roller set works the neck and back while a separate 3D set works the glutes and hamstrings at the same time, both guided by an SL-Track that runs from the neck to the hamstrings.

A smart body scan sets the rollers to your frame before the program starts, and a sensor in the armrest takes a reading that the chair uses to tailor its choice among 16 automatic programs. Seven manual programs are there when you want to set the session yourself.

Twenty-six air cells hold the shoulders, arms and legs, the calf rest kneads, and foot rollers work the soles. Heat warms the lumbar area, the seat and the calves. The legrest extends automatically by up to 10 inches: 7.5 inches at the foot section and 2.5 inches at the calf.

Upright the chair measures 58.5 inches long, 31.5 inches wide and 47 inches high, extending to 79 inches reclined, and it weighs 273.2 lb. A thinner 7-inch touchscreen, quick side controls and voice control run it, and Bluetooth surround speakers, a wireless charger and USB port, LED lighting, hand reflexology and a removable pillow complete it.


Construction

What the Manhattan Duo is built around.

014D + 3D Dual Mechanism

The upper 4D mechanism varies speed, rhythm and depth across the neck and back. The lower 3D mechanism works the glutes and hamstrings at the same time, so the session covers the whole back of the body in parallel rather than in sequence.

02SL-Track from Neck to Hamstrings

The track follows the curve of the spine and runs under the seat, giving the lower mechanism the reach it needs to work the glutes and the tops of the hamstrings.

03Smart Body Scan and Armrest Sensor

The body scan reads your shape and sets the roller path. The armrest sensor adds a reading the chair uses to adjust roller tension and pick an automatic program.

0426-Cell Air Massage with Calf and Foot Work

Air cells hold the shoulders, arms and legs while the rollers work. The calf rest adds kneading and foot rollers work the soles.

05Lumbar, Seat and Calf Heat

Heat runs in three zones: the lower back, the seat and the calves., so the seat is warm while the lower 3D mechanism works the glutes.

0610-Inch Two-Part Legrest Extension

The legrest extends 7.5 inches at the foot section and 2.5 inches at the calf, under remote control., which lets the legrest adjust to both lower-leg length and foot position.


Buyer's Guide

Is a 4D + 3D dual chair the right choice?

A dual-mechanism chair works the upper and lower body at once. The question is how much capability you want in the lower half. The Manhattan Duo uses 3D rollers there, which control depth. Osaki's Grand Duo uses a second 4D set, adding speed and rhythm changes to the glutes and hamstrings.

The Grand Duo also carries 62 air cells and 41 automatic programs against the Manhattan Duo's 26 and 16, and adds a sliding side panel. It is also 2 inches wider at 33.5 inches and 59 lb heavier at 332.3 lb.

Osaki's 4D Orion Duo Mech shares the Manhattan Duo's 4D + 3D layout and the same 16 automatic and 7 manual program count, so compare the two on finish and features rather than on the mechanism.

Plan the room around the 79-inch reclined length. The Manhattan Duo is 31.5 inches wide, needs a 31.5-inch doorway, and ships in one box of 50.8 x 33.5 x 57.9 inches weighing 329.6 lb.
