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 5D+4D Kairos Duo Two roller mechanisms, a 5D upper and a 4D lower, running at once.

The Kairos Duo carries two separate roller mechanisms on one SL-Track. A 5D head works the neck, shoulders and upper back while a 4D head works the lower back, glutes and hamstrings at the same time. A single-mechanism chair has to move one head down the whole back; the Kairos Duo covers both halves in parallel, so a full-back program spends more time on each area.

Osaki's 5D head uses smart pressure sensors that read the back in real time and adjust the head as you shift in the seat.

Twenty automatic programs and five manual modes run from a touchscreen, an armrest button panel, or voice commands. Say "Hello Osaki" or "Hi Osaki" followed by a preset command and the chair starts that function. Fifty-six air cells compress the body.

Heat comes from three places: the upper roller heads, the calf area and a removable heating shawl laid over the front of the body. Foot rollers with reflexology ridges and calf kneading work the lower legs. The chair needs about 1 inch from the wall to recline fully and is rated for users up to 280 lb.


Construction

What the Kairos Duo is built around.

015D Upper and 4D Lower Mechanisms

Two heads share the SL-Track, one above the other. Running both at once means the upper back and the glutes are worked in the same minute, rather than in turn.

02Smart Pressure Sensors

The 5D head reads pressure against the back as it moves and adjusts as you change position. A chair that scans only at the start cannot respond if you slide down the seat mid-session.

03Voice Control and Three Ways to Operate

The chair answers to "Hello Osaki" or "Hi Osaki" followed by preset commands listed in the manual. A touchscreen and an armrest panel cover the same functions by hand.

04Shawl, Roller and Calf Heat

Heated upper roller heads warm the shoulders, a removable shawl warms the chest and front of the body, and calf heat warms the lower legs.

0556-Cell Air System, Foot Rollers and Calf Kneading

Fifty-six air cells cover the body. Foot rollers with reflexology ridges work the soles, and calf kneading adds a rolling motion to the lower legs.

061-Inch Wall Clearance

The chair needs about 1 inch from the wall to recline fully. That keeps a 70-inch reclined chair practical in a smaller room.


Buyer's Guide

Is a dual-mechanism chair worth it?

A dual-mechanism chair earns its place in full-back sessions. With one head, a 20-minute program splits its time between the neck and the glutes. With two, each half of the back gets the whole session. If you mostly target the shoulders, a single-mechanism chair does the same job.

Next, compare heat. Many chairs warm only the lower back. The Kairos Duo heats the upper rollers, the calves and the front of the body through a shawl, which matters most in a cool room.

Osaki's Ai Apex Duo also pairs a 5D upper and 4D lower mechanism. It steps up to 46 automatic programs, 62 air cells, sliding side doors, a 3-stage zero-gravity recline and AI health detection, in a larger 332 lb frame. The Kairos Duo keeps the same dual-mechanism layout at a smaller size.

The Kairos Duo measures 62 inches long, 33 inches wide and 47.5 inches high upright, and 70 inches long reclined. It weighs about 284 lb and ships in two boxes. Plan for a 33-inch doorway with the chair assembled.
