Osaki OS-Pro 4D+4D DuoMax SE Massage Chair

The Osaki OS-Pro 4D+4D DuoMax SE Massage Chair is a premium dual-mechanism chair built for people who want simultaneous upper- and lower-body roller work instead of waiting for one massage mechanism to travel from one area to another. Two independent 4D mechanisms create an eight-roller track massage, while the SL Flex Track, calf rollers, foot rollers, heat, and 38 air cells extend the massage beyond the back.

The hardware backs up the flagship positioning: dual 4D+4D mechanisms, 20 automatic programs, 11 massage styles, intelligent health detection, zero-gravity reclining, a 7.8-inch automatic footrest extension, and a 330 lb maximum user weight. Osaki includes a 5-year warranty consisting of 3 years of full service plus 2 additional years of parts coverage.

Why the 4D+4D Duo Mechanism Matters

The defining feature of the DuoMax SE is its Duo Mech 4D+4D massage system. Instead of a single roller carriage covering the entire back one section at a time, the chair uses two 4D mechanisms that can work different areas at the same time. The rollers adjust massage depth and speed to create a more targeted, human-like massage rhythm across the upper and lower body.

SL Flex Track for Coverage and Stretching

The DuoMax SE uses an SL Flex Track designed to follow the spine while also changing its angle with the backrest. That flexibility allows the roller system to maintain coverage from the neck and shoulders through the lower back and toward the hamstrings while giving the chair more freedom to open the body during recline and stretching programs.

Intelligent Health Detection

Osaki's integrated health-detection system tracks readings including heart rate, blood oxygen level, microcirculation, and fatigue index. The chair uses that information as part of its personalized massage experience. These readings are wellness features of the massage chair and should not be treated as a substitute for medical evaluation or diagnostic equipment.

Lower-Body Massage Goes Beyond Air Compression

The DuoMax SE gives the calves and feet dedicated mechanical massage rather than relying only on airbags. Vertical calf rollers move through the lower legs while air compression adds surrounding pressure. Under the feet, two specialized rollers per foot use reflexology-style ridges to work from heel to toe.

The automatic footrest can extend up to 7.8 inches to accommodate different leg lengths.

Piano-Key Arm Massage and 38 Air Cells

Air compression covers the shoulders, arms, hips, calves, and feet through 38 air cells. The arm section also uses Osaki's piano-key massage design to create more active compression through the hands and forearms than a basic squeeze-and-release arm airbag system.

Two Heating Cores Plus Lower-Back Heat

Two heated jade cores move with the massage system to combine roller pressure with targeted warmth. The chair also provides lower-back heat, with Osaki listing the heating-pad range at approximately 75–83°F.

Zero Gravity Without Requiring a Large Wall Gap

Zero-gravity reclining redistributes body pressure while the massage mechanisms work. Osaki's space-saving design requires approximately 5.5 inches of wall clearance for a full recline, helping a large premium chair fit more efficiently into the room.

20 Automatic Programs and 11 Massage Styles

The DuoMax SE includes 20 automatic massage programs for different routines and focus areas, plus 11 massage styles for more manual control. Programs include options centered on relaxation, waist care, stress release, energy, full-body air massage, legs and feet, and other targeted routines.

Control It from the Chair or Your Phone

Control options include the chair's touchscreen controller, quick-access side controls, smart voice control, and the Osaki DuoMax mobile app for iPhone and Android. Convenience features also include wireless phone charging, USB charging, ambient LED lighting, and HD Bluetooth surround speakers.

The Mattress Clinic offers mattress delivery, in-home setup, adjustable base installation, and optional haul-away services for customers purchasing a new sleep setup from our Moore showroom. Delivery is available in Moore, Oklahoma City, Norman, and many surrounding metro communities.

The service can be as straightforward as delivering and placing a mattress or can include assembly and setup for more involved configurations such as adjustable bases and split king systems. If old-mattress removal is needed, haul-away options can be discussed before delivery is scheduled.

What Mattress Delivery and Setup Can Include

The exact service depends on what you purchase and the type of setup required. Available delivery services may include:

• Delivery of your new mattress to the home
• Placement of the mattress in the intended room
• Adjustable base assembly and setup
• Split king and dual-base setup
• Positioning and basic function checks before the delivery team leaves
• Optional removal of eligible old mattresses or sleep-system components

Delivery pricing, setup requirements, and any requested haul-away service should be confirmed before scheduling so you know what is included before delivery day.

Setup Options for Adjustable and Split King Systems

Adjustable Base Setup

Adjustable bases require more than mattress placement. Depending on the model, setup may include assembly, positioning, connecting components, installing legs or accessories, and confirming that the controls and movement functions operate properly. Customers building an adjustable sleep system can learn more about Adjustable Bases before choosing their setup.

Split King and Dual Adjustable Base Setup

Split king systems involve multiple mattress and base components that need to be positioned together while preserving independent adjustment on each side. If you are still deciding whether this configuration is right for you, see our Split King Mattresses guide. Once purchased, delivery and setup can be coordinated for the complete configuration.

Curbside Delivery

For customers who do not need in-home placement or assembly, curbside delivery may also be available. Ask about this option when arranging delivery so the drop-off location and delivery expectations can be confirmed in advance.

Old Mattress Haul-Away

If you are replacing an existing mattress, ask about haul-away when arranging delivery. Eligible old mattresses and other approved sleep-system components can be removed as part of the scheduled delivery service so you do not have to arrange a separate removal afterward.

Because removal availability can depend on the item and delivery circumstances, confirm what needs to be hauled away before your delivery date. This page refers to haul-away associated with our mattress delivery services rather than a standalone mattress disposal or junk-removal service.

Before Your Mattress Delivery

A few simple preparations can make delivery and setup easier:

• Clear the path from the entrance to the bedroom.
• Remove fragile or obstructing items from hallways and stairways.
• Make enough space around the bed area for mattress placement or base assembly.
• Secure pets before the delivery team arrives.
• Let us know ahead of time about narrow stairways, difficult access, or other conditions that could affect delivery.

Larger installations, particularly adjustable or split configurations, can take longer than a standard mattress delivery. Delivery timing and any special setup requirements can be discussed when the appointment is arranged.

Mattress Delivery in Moore and the Oklahoma City Metro

Our primary delivery area includes Moore, Oklahoma City, Norman, and surrounding communities. Delivery may also be available to areas such as Newcastle, Mustang, Yukon, Midwest City, Del City, and other locations depending on scheduling and distance.

If you live outside the immediate Moore or Oklahoma City area, ask us about delivery availability and pricing before purchasing. We can confirm whether your location is within the current delivery area and what service options are available.

Arrange Delivery, Setup, and Haul-Away

Delivery details are arranged through The Mattress Clinic when you purchase your mattress or sleep system. Before scheduling, we can confirm the delivery location, what is being installed, whether haul-away is needed, and any access considerations that may affect the setup.

We help our customers compare options, test comfort levels, and choose what best matches your body and sleep needs. We take a lot of pride in getting this right the first time — and the vast majority of customers never need a comfort exchange. If you ever decide you’d prefer a different feel, our 365 Night Mattress Exchange gives you a clear backup plan. And if you do need to make a change, we’re not guessing — we use your real feedback from the first mattress to guide you into an even better match.

This program is designed to give you confidence when you buy. You’re getting real guidance up front, and a safety net after, so you can feel secure in your decision either way.

Why This Helps You Buy With Confidence

Your body and a new mattress both need time to adjust. A mattress that feels “different” at first often becomes the perfect fit once your body settles in and pressure points change. The 365 Night Mattress Exchange is built around that reality. It encourages you to give your mattress a real chance, while still protecting you if you truly need a comfort change later.

And if you do exchange, that second selection is usually even more dialed-in — because we’re making the decision based on what you experienced over real nights of sleep, not just a few minutes in the showroom.

What the Exchange Gives You

The 365 Night Mattress Exchange allows you to reselect a different comfort option within one year of purchase. You’ll stay in the same mattress size, and you’ll have the freedom to choose a comfort level that fits you better. If your new choice is a higher value, you pay the difference. If it’s lower, the exchange still gives you the ability to reselect based on comfort.

How to Start an Exchange Request

If you ever need to begin an exchange request, email us at contact@mattressclinic.com with a picture of the law tag and a description of what you’re experiencing. From there, our team will guide you through the next steps and help you make the best possible reselect.

If the Exact Same Mattress Drops in Price, We’ll Make It Right

Buying a mattress is a big decision, and price confidence matters. If you find the exact same mattress advertised for less after your purchase, we want you to feel confident you paid the right price.

That’s why The Mattress Clinic offers a 180 Day Price Match on qualifying mattresses.

If a valid lower advertised price appears within 180 days of your purchase, we’ll review it and make it right.

How the 180 Day Price Match Works

If you come across a lower advertised price, the process is simple:

• The mattress must be the same brand, model, and size

• The price must be publicly advertised and currently available

• Bring the advertisement (link, screenshot, or printed copy)

• Visit our showroom so we can verify the details in person

Verification is completed in-store to ensure accuracy and fairness for everyone. All requests are subject to verification and approval.

What This Covers

• New mattresses purchased from The Mattress Clinic

• Name-for-name product comparisons

• Valid price match requests made within 180 days of purchase

This is designed to protect you from price regret — without games or gimmicks.

Why Local Pricing Still Works

Many shoppers worry that buying locally means paying more — especially with so many online deals available.

At The Mattress Clinic, that isn’t the case.

We operate differently than large chains and online-only retailers. By keeping operations efficient and managing most areas of the business in-house, we’re able to control costs without sacrificing service, selection, or support.

That’s why we can confidently stand behind our pricing — and why our 180 Day Price Match exists in the first place.

If you find the exact same mattress advertised for less, we’ll review it and make it right.
