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 Trion Flex Duo 4D+3D Two mechanisms, a flex track and leg rests that move like a walking stride.

The Trion Flex Duo's leg rests move independently. Osaki calls it Walking Technology: the two leg rests work in a scissor action that imitates a walking stride, stretching the lower back, glutes, hamstrings and knees one side at a time. A one-piece ottoman moves both legs together; splitting it lets the chair work each side separately, and the foot massage follows each leg's position.

Above the seat, Osaki's Duo Mech pairs a 4D mechanism for the back with a 3D mechanism for the glutes and hamstrings, both on an SL Flex Track. Osaki says the track bends with the spine's curve as the chair reclines, holding roller pressure and depth from the neck to the glutes.

Sensor handles feed Osaki's Intelligent Health Detection, which Osaki says reads muscle tension, heart rate and physical fatigue levels and then selects a session. Smart Voice Control runs the chair without the remote, and a body scan sets roller positions for each user.

Fifty air cells cover the body, three arm rollers work the forearms, and the foot rollers are heated. Heat also runs in the lumbar and calves. The chair has 12 automatic programs and 6 massage styles, two zero gravity stages, Bluetooth speakers, a wireless charging pad and a USB port, and authorized dealers rate it for users up to 270 lb.


Construction

What the Trion Flex Duo is built around.

01Walking Technology with Independent Leg Rests

The leg rests move separately in a scissor action that imitates walking, stretching the hamstrings, knees, glutes and lower back on alternate sides. Foot massage follows the position of each leg, so the feet stay on the rollers as the legs move.

02Duo Mech 4D+3D Mechanism

A 4D mechanism works the back, varying depth and speed through each stroke, while a separate 3D mechanism works the glutes and hamstrings. With two mechanisms, the lower body has dedicated rollers instead of waiting for a single carriage to travel down from the shoulders.

03SL Flex Track

The flexible track extends as the chair reclines and bends with the spine. Osaki designed it to keep roller pressure consistent from the neck and shoulders through the hips and thighs, including at full recline.

04Intelligent Health Detection and Smart Voice Control

Sensor handles take readings, and the chair selects a session from them. Smart Voice Control starts programs and adjusts the chair by spoken command, which matters most once you are reclined and the remote is out of reach.

05Heated Foot Rollers and Three Arm Rollers

The foot rollers carry their own heat, and Osaki lists three arm rollers that work the forearms in addition to the air cells. The hands, arms and feet get rolling pressure, not only compression.

0650-Cell Air Compression with Lumbar and Calf Heat

Fifty air cells cover the body, and the footrest unit carries its own compression cells. Heat runs in the lumbar and calves as well as the feet, so the lower body is warmed in three places during a session.


Buyer's Guide

Is a dual-mechanism chair worth it?

A single-mechanism chair has one roller carriage that travels the whole track, so the glutes and hamstrings get attention only when the carriage reaches them. A dual mechanism puts dedicated rollers on the lower body. On the Trion, that second unit is 3D and works the glutes and hamstrings while the 4D unit stays on the back.

The second question is what happens below the knee. The Trion splits the leg rest in two for Walking Technology, heats the foot rollers and adds calf heat. If the leg section matters to you as much as the back, that combination is the case for this chair.

Within Osaki's line, the Platinum Solis 4D also uses a flexible track and voice control, stretches further to 190°, and carries 54 air cells with lumbar heat. Osaki does not list health detection, a 3D lower mechanism or Walking Technology for it. The Platinum Vera 4D offers armrest sensors that steer a single 4D mechanism on a standard SL-Track, with lumbar and calf heat.

Check the footprint before ordering. The Trion measures 71 inches long, 33 inches wide and 47.5 inches high upright, and authorized dealers rate it for users up to 270 lb. It reclines through two zero gravity stages from the touchscreen controller or by voice.
