4D Massage Roller
The Osaki Japan Premium 4S Massage Chair comes equipped with a 4D Massage Roller. This allows the massage chair to press in and out up to 12.5cm to provide a better massage and also allows for 12 strength adjustments to further customize your massage.
Double Sensing Body Scan
The Japan Premium 4S Japan Massage Chair is equipped with a dual auto detection body scan that optimizes the roller to detect your acupoints along your back and even optimize the depth of the massage. This will enable you to get the most customized massage possible as the computer will map the length of your spine and width of your shoulders.
12 Strength Adjustments
There are 12 levels of strength adjustment in the Osaki Japan Premium 4s to really fine tune the applied strength of the massage rollers. Most massage chairs have 3-5 levels of adjustments, and having 12 makes the Premium 4S even more versatile.
Located in the feet area and lumbar area are infrared heating pads that warm up your muscles and joints. As the muscles warm up, the tissue will loosen up and allow the massage chair to provide you with a better, more therapeutic massage. Note: you will not feel the heat as prevalently as you would with normal heating elements however you will get even more healing benefits at a cellular level with the Infrared featured in the 4s.
Leg, Calf & Feet Massage
The airbags will inflate and deflate both the side and back of the calves to stimulate the Zu San Ri acupoint. This has been known to boost your immune system and even your overall energy levels. The airbags also press your feet into the acupressure nodes at the bottom of the soles that will help alleviate fatigue and tension.
Osaki Japan Premium 4S Air Compression
There are 34 airbags that provide a thorough and full body compression massage targeting your feet and legs, hands and arms, shoulders, and waist and pelvis. The soothing air massage combined with the massage roller offers a full body massage to work out any tension and stress that you may have. The Triple Mode Air System will provide therapeutic relief for sore muscles and promote blood circulation. This flow rate adjustment comes with 3 modes to tailor your massage to your needs: Knead, Pulse, and Normal.
Osaki has re-engineered its air massage technology, reducing the total airbags but increasing the surface area coverage. This reduces the stress on the air pump and valves, ultimately extends the longevity and dependability of this component.
Outer Shoulder Massager: located on the upper sides of the backrest, there are 2 airbag massagers on each side. As the air bags inflate it will compress the shoulder inwards. The shoulder airbags may also inflate to hold you in place as the back rollers apply a soothing massage.
Hand & Arm Massager: As you insert your arms into the unique butterfly design, it will position the palm of the hands vertically. Simultaneously the hands and forearms will be massaged as the air bag inflates. The tapered design will contour the arms for an even massage.
Hip Massage: Along the sides of the seat base are airbags on each side. As they inflate it will squeeze the hips.
Foot & Calf Massage:The calve massage is curved on the outer walls so that it will wrap around the calves as it inflates. There are also airbags on the back of the calves for a more complete massage. The feet are massaged by airbags which are lined the along the sides, pressing the feet down to the base of the foot massager.
New Dimensional Kneading Technique
Kneading technique is the heart of the massage chair. Kneading in Osaki Japan Premium 4.0 relies on a new sensor which optimizes the rubbing by further implementing the new dimensional massage.

All of our items have a FREE SHIPPING OPTION within the contiguous United States (we will need to quote out all Alaska, Hawaii, Puerto Rico and Canadian orders)
We strive to ship your items as fast as humanly possible--and try to regularly beat our goal of 5 business days from your order date. We will send you tracking information within 24 hours of your order leaving the warehouse to the e-mail address you provided when checking out. If you do not receive tracking information from us within six business days of your order, feel free to follow up with us at email@example.com.
All orders canceled after 48 hours are subject to cc administration fees (since those are not refundable to us), if your order has not shipped.
If you choose our free shipping option,you can expect to receive your item curbside within 7-10 business days of your item shipping--oftentimes sooner. Our carriers will typically bring your chair to the front door for you--many of our chairs come in 2-3 boxes. Oftentimes, the chair arrives fully reclined in one big box with the armrests in another box and the footrest in the last box. Typical assembly requires attaching the armrests and the footrest. In some cases, a pedestal for your remote. We have many installation videos available on our site and youtube channel. If you do decide to go with curbside delivery, expect to have help with moving the chair into your home and desired location as many of our chairs are quite heavy.
A dolly (or 2)will greatly assist in moving your chair to the right location in your home
Tip for moving your chair once it is assembled: fully recline your chair; place dolly next to the chair and "tip" chair onto its side on the dolly. You will then be able to roll your chair wherever you would like! (Note: this is not advisable for the OHCO M.8 and would void your warranty)
If you choose white glove delivery, there will be an additional charge of $250. Your item will be delivered to your home, placed in the room of your choice exactly where you want it and set up. Because we have to use an outside contractor for this service, your delivery time will be extended by one week. Also, if you have a difficult location (several stairs with challenging turns etc) please send us pictures so that we can make sure the delivery company is prepared. If they arrive and it requires a 3rd man, there'll be extra charges such as an extra return trip and fee--we don't want you (or us) to have any surprises. Please really think about if you need white glove delivery--it's a lot more challenging and expensive to add it after your order has been placed.
We will do everything possible to ensure that your item arrives in the same condition that it left the manufacturer. Any product damage or loss is the responsibility of the shipping company, not Wish Rock Relaxation.
BEFORE you sign the shipping weigh bill, please THOROUGHLY INSPECT YOUR ITEM.Signing for receipt of a damaged product removes the liability of the shipping company and Wish Rock Relaxation. Once you accept your shipment as non-damaged, the item is yours.
***If your item looks questionableupon delivery, CALL US at 803-574-9474 (WISH) and we'll immediately get the manufacturer involved while the Shipping Agent is on-site.****
30 Day Return Policy
We want this to be one of the best purchases that you've ever made! If you don't completely love your item, we will work with you to get into the right chair OR you can simply return it within 30 days of the ship date.
If you'd like to exchange your chair for another chair we carry, we would love to keep your business and will work to absorb all the fees to help you get into a better chair to meet your needs.
Item must be repackaged in it's original packaging, and must include all parts, hardware, controller and accessories. If you no longer have packaging, you will need to supply or pay for repackaging and likely a white glove pickup.
Applies only to orders within the continental US. If we've shipped a chair to you in Hawaii, Alaska, Puerto Rico or abroad the shipping fees were likely $800-$1200 in one direction.
In the event that you have technical/quality issues with your chair, we will work with you and the manufacturer to make sure that we either repair your chair, replace it or exchange it for an equal or better chair. We will do everything possible to make this right. If you choose to refuse repair or replacement, you will be responsible for the shipping in both directions and any fees associated.
FFL Brands (OHCO, Panasonic, D.Core and Positive Posture) no longer accept any returns; because of this, FFL Brands are now completely excluded from our return policy.
Restocking fees are also typical in the industry. Specifically, several of our suppliers do charge them -- Human Touch, Cozzia (Svago, JP Medics, ErgoTec) and UltraComfort are 15% while Synca (Johnson) is 20%.
We will work with you to absorb the shipping and restocking fees if you choose to switch to another chair with us. If you end up wanting to return your item, you will be responsible for the shipping in both directions and any applicable restocking fees.
