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 OS-4000LS A 2D chair with a 42-inch L-Track and 24 air cells.

The OS-4000LS is the L-Track model in Osaki's 4000 Series. Its 2D rollers run a 42-inch L-Track that starts at the neck, curves under the seat past the glutes and ends at the back of the thighs. That L-shaped lower section is the reason to buy it over a straight-track chair: the rollers work the seat and upper hamstrings instead of stopping at the lower back.

Osaki chose a 2D mechanism here. The rollers move up, down and side to side along a fixed path, without the depth control of a 3D or 4D chair, which gives a consistent, predictable stroke.

Twenty-four air cells add compression around the body, the chair massages the feet and calves, and two heating pads, one on each side of the lower lumbar area, warm the lower back. Osaki advises running the lumbar heat for no more than 30 minutes a day.

Six automatic programs combine kneading, tapping, shiatsu and rolling, and a body scan reads the user before the massage starts. A 3-level shoulder adjustment moves the shoulder airbags to suit different builds, and the chair reclines to a zero gravity position.


Construction

What the 4000LS is built around.

0142-Inch L-Track Roller Path

The track measures 42 inches and bends under the seat, so the rollers travel from the neck past the glutes to the back of the thighs. On a straight S-Track chair, the seat and hamstrings get air pressure at most; here they get roller work.

022D Roller Mechanism

The 2D rollers move vertically and horizontally along the track without pushing forward into the back. The result is a steady, even pressure, a reasonable fit for users who find deeper 3D and 4D chairs too firm.

0324-Cell Air Compression

Twenty-four air cells inflate around the body to add squeezing pressure the 2D rollers do not provide. Outer shoulder airbags are part of that system.

04Dual Lumbar Heating Pads

Two pads, one either side of the lower lumbar spine, warm the lower back during the massage. Osaki's guidance is to keep heat sessions to 30 minutes or less per day.

05Body Scan with 3-Level Shoulder Adjustment

A body scan reads the user before the program starts, and the shoulder airbags can be set to one of three levels, so the shoulder compression lines up with users of different heights.

06Zero Gravity Recline

The chair reclines to a zero gravity position with the legs raised, which moves more of your weight onto the backrest and the rollers.


Buyer's Guide

Choosing between 2D and 3D on a budget.

The first decision with an entry-level chair is the mechanism. The OS-4000LS uses 2D rollers, which trace the track without changing depth. A 3D chair such as Osaki's 3D Dreamer V2 adjusts how far the rollers press forward, which lets the chair go deeper into the back when you want it.

The second is track shape. The OS-4000LS's 42-inch L-Track reaches under the seat to the back of the thighs, the same coverage zone the Dreamer V2's SL-Track reaches. If you sit for long hours and want the seat worked, an L-shaped track matters more than the roller dimension.

Air and heat are where the two chairs separate. The OS-4000LS has 24 air cells and lumbar heat. The Dreamer V2 has 72 air cells and heat at the lumbar area, hips, feet and rollers.

The OS-4000LS keeps to the basics that define an L-Track chair: roller coverage to the back of the thighs, body scan, zero gravity and lumbar heat, on a simpler 2D mechanism with six programs.
