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 Sleep Great or Exchange Guarantee

180 Night Low Price Promise

Return Policy 



365 Night Sleep Great or Exchange Guarantee

A new mattress is like a new pair of shoes—it takes time for the new materials and your body to adjust to each other. And with the wrong socks (bedding), you could end up hating the correct shoes for you. Typically, it takes about 35–40 days for a mattress to start performing at its best if you use the proper bedding. After this “break-in period,” if you feel a different mattress style might work better, you may exchange your mattress up to 365 days from the purchase date. Using our bedding products with our mattresses ensures that the bedding isn’t causing any issues and that it is, in fact, the mattress that’s the problem. This is why you need a protector & pillow from us to receive the Exchange Guarantee.

These policies constitute the “365 Night Sleep Great or Exchange Guarantee” 
A $199 or 10% Exchange Fee (whichever is greater) applies to all reselections. This fee covers delivery for swapping the mattresses up to 20 miles from the store. The Mattress Clinic will allow a one-time re-selection ONLY after the 35-day adjustment or “break-in” period (Tempur-Latex 40-days). You have 365 days from the purchased date to exchange your mattress. You may select a mattress of equal or greater value of the same size. If you select a sleep surface of greater value, you will be responsible for the difference in price. If a reselection is of lesser value, no refund will be given. The original mattress purchase must include a mattress protector and pillow purchased before the mattress is received. The mattress surrendered must be stain free and odor free. We are unable to exchange stained, unsanitary, odor damaged (smoke/pets etc.), or damaged (ripped, burns, etc) mattresses under the Exchange Guarantee. Products must have been used only for their intended purpose. This includes using the product on an appropriate base, frame, or foundation.

Please take your time in your reselection choice; only ONE comfort exchange is allowed per customer. keep all receipts and original tags on your mattress. The Exchange Guarantee will be voided if you remove the original tag from the mattress or lose your proof of purchase. 
 

Reselections are not allowed for issues regarding mattress size or height. Bedding accessories such as pillows, protectors, sheets, adjustable bases, bedding foundation or furniture, are not eligible for exchanges. Reselections are not valid on “special sizes” (California King, split Queen, Etc.), custom orders, clearance merchandise, floor models or warranty exchanges. Your mattress reselection will be sold at “normal” sale price. Any discounts/gifts given with your original purchase of mattress, sheet set(s), mattress protector(s), pillow, and/or non-purchased gift cards will be added to the exchange fee. This means if you receive a discount/gift with your mattress and/or qualifying items and want to exchange it for the same mattress but a different feel, you are to pay the difference of the discount(s)/gift given, the exchange fee, plus any price increases made since your purchase (if increased). Your re-selection must be the same size as your original mattress purchase, Example: Queen for Queen.
