Osaki OS-Aster - 2D L-track with smooth rollers @ an affordable price   

  • Osaki Aster - L-Track Massage Chair

    47" SL-Track Roller

    The Osaki Aster offers a comprehensive and consistent massage experience with their 47" SL-Track Roller. Rollers begin at the neck and follow the curvature of the spine (like an S-Track) to the tailbone where the rollers curve around the glutes in an L shape (L-Track) massaging all the way to the glutes and hamstrings.  

  • Osaki OS-Aster - Zero Gravity

    Zero Gravity Position

    Originally created by NASA engineers to eliminate the stress and compression astronauts experienced during take-offs and landings, the Zero Gravity position has become a very popular feature.  Considered by many chiropractors as the "healthiest way to sit."  The Osaki OS-Aster features a zero gravity position to enjoy all of your massages in.

  • Osaki OS-Aster - Full Body Air Compression

    Full Body Air Compression (18 Airbags)

    The Osaki OS-Aster features an 18 airbag full body air compression system that will gently squeeze and compress your muscles to enhance and deepen the overall massage experience.  Airbags are located in the shoulders, arms, calves and feet.  Air compression helps to increase your blood circuation in order to improve your overall experience and promote healing.

  • Osaki Pro Maxim - Foot Rollers

    Foot Rollers

    Two rows of spinning reflexology massagers are located on the bottom of the feet of the Osakie Aster.  These rollers provide a refreshing/kneading massage to the bottom of the feet similar to reflexology.  If you've never experienced a massage chair equipped with foot rollers, you are in for a major treat!  The rollers stimulate acupuncture reflexology points along the bottom of the foot while the airbags inflate along the sides to create a much deeper and satisfying massage.

  • Osaki OS-Aster - Space Saver Technology

    Space Saving Technology (10" clearance)

    If you have space constraints, this chair will not disappoint.  With only 10" of clearance required from the wall, the Osaki Aster is able to fit into the smallest of spaces.  Most typical massage chairs take up a lot of space with many requiring up to 3 feet behind the backrest in order for the chair to fully recline. 

  • Osaki OS-Aster - Easy to use Remote

    Easy to Use Remote

    The Osaki Aster offers a very intuitive and easy-to-use remote control with an easy view screen displaying the functions that are activated in the chair.  You can select the type of massage, speed and location.  You also have the option to operate in manual mode too.

  • Osaki OS-Aster - Extendable Footrest

    Extendable Footrest

    The Osaki OS-Aster Massage Chair is even suitable for very tall people with an extendable footrest of up to 7 inches.

Additional Features:

  • Osaki Pro Maxim programs

    6 Automatic Programs + Manual Mode:  

    The Osaki OS-Aster has 6 pre-set massage programs loaded into the computer diagnostics of the chair.  Each program is unique:  Comfort (loosens the muscles), Relax (deep tissue massage throughout key acupressure points to relax sore areas), Full Body (full body overall massage), Neck & Shoulder, Back & Waist, Stretch (footrest and backrest will move together combined with the air pressure to gently stretch your body).  There are also 5 distinct massage styles featured:  Kneading, Tapping, Shiatsu, Knocking and Kneading/Tapping. 


The Apex, Osaki and Titan brands are all covered under the same warranty policy of Titan Chair, LLC.  Titan offers a very comprehensive warranty package that covers parts, labor and structural framework.

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 info@wishrockrelaxation.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 questionable upon 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.
