Order the KOYO 303TS 4D Massage Chair Online

The KOYO 303TS 4D massage chair delivers a versatile, full-body massage experience using advanced 4D massage technology, an SL-track system, and precision-engineered components for smooth, controlled performance. Order this massage chair online and have it delivered to your home, combining Japanese-built reliability with nuanced, human-like massage movements. Designed to replicate the feel of a skilled massage therapist’s hands, the 303TS blends intelligent customization, consistent pressure, and long-term dependability into one refined system.

Why the KOYO 303TS 4D Massage Chair Stands Out

• 4D massage mechanism with anthropoid silicone massage heads
• Hybrid SL-track system for precise, full-body coverage
• Precision brushless motor for quiet, accurate performance
• Calf and low back heat for muscle relaxation
• Full-body air massage system from shoulders to feet
• Automatic body scan for personalized positioning
• Zero gravity recline for improved circulation and comfort
• Built in Japan for performance and durability

4D Massage Technology and Performance

The KOYO 303TS features a 4D massage mechanism designed to replicate the feel and movement of human hands, using anthropoid silicone massage heads and variable speed control to adjust intensity throughout each session.

This system performs a range of massage techniques including kneading, tapping, rolling, and pressing, helping to improve circulation, reduce muscle tension, and provide full-body relief. The precision brushless motor allows for accurate control and quiet operation, making the massage feel smooth and consistent rather than mechanical.

The hybrid SL-track combines the extended reach of an L-track with the contouring shape of an S-track, allowing the rollers to follow the natural curve of your spine while continuing through the lower back and into the hips. This ensures more complete coverage without losing contact in key areas.

Comfort and Customization Features

The automatic body scan system detects your shoulder position at the start of each session, allowing the chair to tailor the massage to your body type for better alignment and consistent pressure.

Full-body air massage uses strategically placed air cells to provide compression across the arms, shoulders, hips, legs, and feet. This helps rejuvenate fatigued muscles, improve circulation, and enhance the overall massage experience.

Zero gravity reclining positions your body to reduce spinal pressure and improve comfort, while infrared heat in the lower back and calves helps loosen tight muscles and enhance relaxation.

The touchscreen remote is designed for simplicity, with clear menus and easy navigation, while the fingertip control dial allows quick adjustments without interrupting your session.

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

(405) 735-6688

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.
