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 OP-4D Master Ten airbags that press down over the tops of the shoulders.

The OP-4D Master's defining feature sits at the top of the backrest. Ten airbags in the shoulder section press down over the tops of the shoulders, where the air cells in most chairs only squeeze from the sides. Osaki places this model in its Platinum line.

Below the shoulders, a 4D mechanism runs a laser-crafted steel SL-Track from the neck and shoulders to the hamstrings. Osaki lists muscle tension detection, and the chair offers 16 automatic programs and 6 massage styles: kneading, two tapping styles, two shiatsu styles and rolling.

The chair carries 46 air cells in total. Each foot sits over three rollers, and the footrest extends automatically by up to 8 inches. Heat warms the lumbar area and the feet.

Recline is one-stage zero gravity, and the frame needs 3 inches of wall clearance. Upright it measures 68 inches long, 31.5 inches wide and 50.5 inches high, and 72 inches long reclined. A swivel touchscreen, a side panel, Alexa voice commands and Osaki's app control it; Bluetooth speakers, a phone charging surface, a USB port, a negative ion generator and LED lighting complete it.


Construction

What the OP-4D Master is built around.

01Ten Over-the-Shoulder Airbags

Ten airbags in the shoulder section press down on the tops of the shoulders. Standard shoulder air cells press inward from the sides; these press from above.

024D Mechanism with Tension Detection

The 4D rollers vary speed, depth and rhythm, and Osaki lists muscle tension detection to shape the program. Strength and speed can be set by the user.

03Laser-Crafted Steel SL-Track

The track follows the S-curve of the spine and continues under the seat to the hamstrings, so the glutes and the backs of the thighs are part of every full-body program.

0446 Air Cells and Three Rollers per Foot

Forty-six air cells work the shoulders, arms, legs and seat. Each foot sits over three rollers.

05Lumbar and Foot Heat

Heat warms the lower back and the feet during the massage, and the footrest heat runs while the foot rollers work.

06One-Stage Zero Gravity with 3-Inch Wall Clearance

The chair slides forward as it reclines into zero gravity, so it needs only 3 inches behind it. The footrest extends automatically up to 8 inches for taller users.


Buyer's Guide

What to compare in a 4D chair.

Start with the shoulders. Most chairs, including Osaki's JP-Nexus, compress the shoulders from the sides. The OP-4D Master adds ten airbags that press from above, and that is the reason to choose it over a 4D chair with a similar track.

Then compare program depth. The Master offers 16 automatic programs and 6 massage styles. The JP-Nexus matches the 16 automatic programs and adds 35 manual programs, and it is made in Japan. The Master answers with 46 air cells against the Nexus's 34.

Fit is the third check. The Master's seat is 18 inches wide and its shoulder width is 24.5 inches, and the footrest extends up to 8 inches. If you sit wider than 18 inches at the hip, try the seat before you buy.

Finally, the extras. Alexa voice control, the app, the phone charging surface and the negative ion generator add convenience, but the shoulder airbags, the 4D rollers and the SL-Track decide the massage.
