Product Description

The feature-rich KOYO® 303TS is designed and built in Japan to provide a versatile and nuanced massage experience with maximum performance and dependability. Its 4D massage mechanism with anthropoid silicone massage heads faithfully replicates the feel and movements of a Japanese massage master’s hands.

Product Features

Calf & Low Back Heat

Soothing infrared heat complements the therapeutic calf and low back massage, loosening tight muscles aiding in relaxation.

Full Body Air Massage (arm, shoulder, feet, leg, seat)

Strategically placed air cells provide relief to your feet, calves, thighs, hamstrings, arms, hands, and shoulders.

SL-Track

The KOYO® hybrid SL-track combines the benefits of a traditional L-track’s broad body coverage and zero gravity recline, with the addition of a curved S shape that conforms more closely to the contours of your body, allowing for a more precise massage.

Auto Body Scan

KOYO® chairs provide a personalized massage experience by beginning each session with an automatic body scan, allowing the 4D massage mechanism to tailor its movements to each part of your body.

4D Massage Mechanism with Anthropoid Silicone Massage Heads and Precision Brushless Motor

The KOYO® 4D massage mechanism is programmed to mobilize your spine, relax your mind, and help you recover from the stresses and strains of your day. With carefully designed kneading, tapping, rolling, and pressing movements, it improves blood flow and soothes tired muscles. Its varying speed capability and pliable silicon massage heads make the massage feel like human hands on your back. The precision brushless motor provides accurate speed control and extra-quiet operation.

Zero Gravity

With the push of a button, enter the rejuvenative and deeply relaxing zero gravity recline position. Improve blood circulation, breathe easier and deeper, and alleviate pressure on your joints and spine.

Bluetooth Sound System

Drift off to your favorite classical piece. Energize with some hard-driving rock ‘n’ roll. Or listen to a peaceful nature soundtrack. Just sync your smart device to the chair, and your soundtrack will be as personalized as your massage.

Foot Rollers

Thoughtfully-shaped foot rollers rub, roll, and squeeze your tired and sore feet. Working in concert with the foot air massage cells, KOYO’s® foot rollers encourage blood flow, work muscles, and mobilize your entire foot.

Super-Simple Touch Screen Remote

Life is stressful enough. Your massage chair remote shouldn’t be. We have designed the KOYO 303TS remote to be simple to learn to use. In just minutes, anyone can learn to control the full functionality of the chair. Menus are clear. Buttons are big. This touchscreen remote is dazzling in its simplicity.

Fingertip Control Dial

This simple tactile control located at the fingertips of your left hand allows for instant and intuitive personalized adjustments to the feel of your massage, without having to open an eyelid.

365-Night Comfort Exchange

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.

Shop With Price Confidence for 180 Days

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

The Mattress Clinic
803 North Moore Avenue Ste 103
Moore, OK 73160
(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.


Questions? We’re Here to Help

If you’re unsure whether a price qualifies, feel free to call or stop by before making the trip.
