Kahuna EM-8500 Massage Chair

The Kahuna EM-8500 is a 4D adjustable massage chair fitted with its advanced HSL-track roller mechanism. The HSL-track system is an Advanced SL-track system with an additional curve in your spine and then wraps around the glutes while giving you complete control over the intensity with the 4D mechanism. The Kahuna EM-8500 has some very advanced features including a Negative ion system, 3 stages of Zero Gravity, dual foot, and calf rollers plus 24 auto massage programs and 6 manual programs. The Kahuna EM-8500 is suitable for people up to 6'2" tall and 250 pounds.


  • Advanced 4D Mechanism

    The Kahuna EM-8500 Massage Chair comes equipped with the new 4D Massage Mechanism with width control. What this means is that the rollers feature variable speed where the massage strokes speed up and slow down mid-stroke to create the feeling of a real person massaging you. It’s perfect when you want different pressure and speed in different areas of your body.

  • HSL-Track

    The Kahuna EM-8500 Massage Chair also comes with the latest massage rolling track, which massages from your neck, all the way down to your glutes and upper hamstrings. This is called an "HSL" rolling track or Hyper SL-Track.

  • Zero Gravity (3-Stage)

    The Kahuna EM-8500 Massage Chair comes with zero gravity, giving the user a weightless feeling during the massage. Zero Gravity gives the user an option on how far back they want their chair to recline automatically, or you can adjust the chair manually in the remote.

  • Automatic Body Scan

    Upon startup, the Kahuna EM-8500 Massage Chair performs a body scan to precisely map the key areas of the neck and back in order to ensure the chair adjusts to fit every body type perfectly. The scanning technology will detect the length of your spine and the width of your shoulders in order to give you the most customized experience possible. 

  • Automatic Massage (24 Auto Programs)

    This Kahuna EM-8500 Massage Chair comes with 24 Automatic programs and is divided into three sets of programs called Basic, Specialty, and Elite Target. Basic programs for your daily life are Renew, Refresh, Recovery, Stretch, Morning, Night, Anti-stress and, Energize. Specialty customized programs for different lifestyles are called Salesman, Housewife, Office Clerk, Game Player, Driver, Sports Man, Server, and Senior. And the last program is called the Elite Target that specialized in the Neck, Neck&Shoulder, Back Relief, Waist, Leg Feet, Upperbody and Lower Body.

  • SPACE SAVER (3")

    Along with the Zero-Gravity recline, the Kahuna EM-8500 Massage Chair comes standard with space-saving technology, that allows you to place the chair within 3 inches of the wall, even while fully reclined. The chair will move out first and then up while moving into Zero-Gravity.

  • Massage Techniques (6)

    The Kahuna EM-8500 Massage Chair comes with 6 unique massage techniques in the manual mode; Kneading, Tapping, Rolling, Flapping, Tapping + Kneading, and Combination.

  • Heat Therapy (Lumbar, Legs, Feet)

    The Kahuna EM-8500 Massage Chair has heating pads located on the Lumbar, Legs, and Feet area. It offers heat therapy which is a great compliment to the roller and airbag massage. Heating the body’s temperature is known to increase blood circulation and loosen tense muscles.

  • LEG EXTENSION (6")

    Titan Kahuna EM-8500 Massage Chair has an extendable footrest that can be extended up to 6 Inches to reach the desired comfortable position which fits a user’s various height. 

  • Bluetooth

    Titan Kahuna EM-8500 Massage Chair is equipped with Bluetooth technology that allows the user to listen to their favorite music and phone calls on high quality speakers in the headrest.

  • SIDE PANEL CONTROLLER

    Designed that the user can easily control the chair without using a remote tablet. The user can adjust the 4D intensity, reclining positions, Zero Gravity, Auto massage program, and Heating function.

  • Tablet Remote & Quick Controls

    The Kahuna EM-8500 Massage Chair remote is upgraded to Touch Screen Remote Tablet. It has an easy view screen displaying the function of the chair. It also has a magnetic holder that holds the remote into place. The interface is very easy to navigate and adjust settings.

Shipping & Return Info

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.

Cancellation

All canceled orders are subject to your cc fees (close to 3%) which are non-refundable plus a $20 processing fee, whether or not your order has shipped. If your order has shipped, you (the buyer) will also be responsible for actual return shipping charges and any re-consignment fees associated. Refunds will only be issued to the original credit card that you used when placing your order.  

Shipping

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!  

If you choose white glove delivery, there will be an additional charge of $250 (even though we may spend more than $600 for this delivery option). Your item will be delivered to your home, placed in the room of your choice exactly where you want it and set up.  All debris will also be removed.  

  • Your chair will travel the bulk of its journey via LTL Freight and then transfer hands to the final mile/white glove delivery company.  Because we have to use an outside contractor for this service, your delivery time will be extended by one week. 
  • You will need to notify the White Glove company how many stairs are required for the delivery into the house and location of your choice when they call you to schedule your delivery.  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 will 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.
  • All debris (boxes) will be removed with white glove delivery. If you end up returning your item or exchanging it for something else, it will also require a white glove pickup which can be quite costly.  Please keep this in mind as the delivery company is removing your debris.

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. This applies to all of our manufacturers except for UltraComfort and our Refurbished/Open Box/Certified Pre Owned chairs. They now no longer accept any form of return or SWAP out due to buyer's remorse.  However, if your chair arrives damaged, they will replace it. 

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 its 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. 
  • If there are quality issues with our chair, we will work with you to get the chair repaired, replaced or exchanged for a different chair. If you refuse repair, replacement or even an upgrade, then you will be responsible for the shipping in both directions and any applicable restocking fees.

Restocking fees are also typical in the industry.  Specifically, several of our suppliers do charge them -- Human Touch and Cozzia (Svago, JP Medics, ErgoTec) are now 15% while Infinity (Kyota, Sharper Image and Rockertech), Daiwa and Synca (Johnson, Inner Balance Wellness) are at 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 actual cost of shipping in both directions and any applicable fees and restocking fees. 

*Swapped chair orders are final sales.  (If you have exchanged one chair for another, the new chair is considered to be a final sale)

 

NOTE:  If you have chosen white glove delivery and then wish to return your chair, you will be responsible for all actual shipping fees incurred with your order.  Because the boxes and packing materials are removed in a white glove delivery, you will also need a white glove pickup of your item which is often much more costly. 

If you refuse repair or replacement of your item, you will be responsible for all shipping fees in both directions and any fees associated.

    Massage Chair FAQs

    General FAQ's for Massage Chairs

    Absolutely!  As long as you use it regularly.  Massage chairs can do things that massage therapists simply can’t – like put you into the weightless zero gravity position.  Also, it’s nice to have a massage available to you on-demand in your home, whenever you’d like to use it.  Massage chairs often will pay for themselves in under a year–especially if you’re someone who regularly gets massages from a therapist.

    Most chairs are suitable for people from 5’ to 6’3” tall and up to 270 pounds.  We do have several models that work for much taller people that are up to 6’4” - 6’9” tall and up to 300 pounds.  We do have a few models that accommodate larger people up to 400lbs.

    We recommend looking at the dimensions of your chair vs your body–if you’ve got a much longer torso, measure the height for seat from the back of the chair up to the top of the seat.  Also of consideration – how big are your feet?  Closed-toe footrests are typically good for people with a size 13 or smaller shoe; anything bigger and it’ll be snug.  Open toe footrests seem to work best for taller people with bigger feet.

    The short answer is that it’s safe for you to use your chair daily.  We recommend 15-30 min sessions daily, depending on your schedule and how you feel.  The more you experience deep tissue massage, the easier it is for your body to tolerate and more used to it you become.  Massage chairs can often deliver a much deeper tissue massage than a therapist over a more sustained time period.  The technology has dramatically improved, allowing for real-time Ai sensing and adjustment to enhance the experience.  It’s a nice addition to your daily health routine.

    Massage chairs work best where you will use it the most!  That being said, massage chairs tend to fit best in living rooms, bedrooms, offices, man caves, relaxation rooms or fitness rooms. 

    Space saver chairs require very little room behind the chair when fully reclined and are perfect for those with smaller spaces. By moving the chair forward during the recline, as little as 1” is required behind the chair.  Make sure you know your space requirements, including where you’d like to put it, how much room you need behind the chair and how big your doorways are. Space saver chairs are perfect for those with smaller spaces.  We also have several compact chairs too.

    All of our massage chairs are made for use in the United States and North America and have standard 110V cords.  We recommend plugging your chair into a surge suppressor to protect it from any power surges during storms. Should you move or need to ship a chair overseas, you will be able to use a transformer to step up or step down the voltage. 

    The zero gravity position has become a common feature in almost all massage chairs because it removes all the pressure from your spine.  By reclining back while raising the legs to heart level, you’re able to achieve a weightless position.  Inspired originally by NASA engineers, zero gravity is now considered the “healthiest way to sit” by many chiropractors and helps to improve circulation, reduce swelling and pressure on the back and spine.

    Delivery & Set-up

    Most of our massage chairs have wheels in the rear for you to easily move it to a different room or out of the way for cleaning. If you have smaller doorways, we have some other ways that will work to move your chair into another room.

    One of our tricks in the industry to easily move it between rooms or into a tighter doorway is to:

    Recline the chair all the way back

    Place a furniture dolly next to the chair

    - Gently roll the chair on its side onto the dolly - this is best done with 2 people to ensure safe placement on the dolly

    - Roll your chair to the  new desired location

    - Gently roll back onto solid ground

    We offer free curbside delivery.  Most of our chairs ship LTL freight throughout the continental US.  We strongly suggest that you request a 2-4 hr delivery window and a “courtesy call” or text when the freight company calls you to schedule your delivery.  They will not schedule your delivery with us; you will need to schedule your delivery directly with the freight company.  White Glove deliveries typically require an extra week or two as your chair will first be delivered and change hands from the long-haul carrier to the final mile white glove delivery company.  Don’t get concerned if your delivery status says ‘delivered’ for a White Glove order–that simply means that it is now in the hands of the white glove agent and you should be expecting a call

    Free Curbside Delivery:  your chair is delivered on a pallet with typically 2-3 boxes.  One for the main body of the chair and the other for the footrest and side panels. Assembly is typically very fast and all tools are included in the box. The hardest and longest part will be breaking down all of the boxes for disposal / recycling. Our delivery team will call you to schedule your delivery.

    • Pro Tip:  we highly encourage you to give your delivery team some snacks / beverages. Sometimes a small tip. If you’re kind, they may bring it into your home, though they are not required to with a curbside delivery
    • **If your box appears to be damaged in any way and you are concerned about the integrity of your chair, please:
    • - Take pictures of the box
    • - Refuse Delivery
    • - Call us immediately at 803-574-9474 and explain what’s going on so that we can assist you

    White Glove Delivery:  we recommend this if you are bringing your chair up or down stairs as these are typically very heavy chairs (sometimes over 300lbs).  There is an extra fee ($250 + depending on the chair/manufacturer) involved and extra time also required.

    We recommend white glove delivery if you are bringing your chair up or down stairs. These are often very heavy chairs that do sometimes require light assembly.  If you cannot find help or manage moving the chair into your home by yourself and desired room of choice, we do recommend white glove delivery.  

    Occasions where White Glove would be necessary:

    • - Placing the chair up or down stairs
    • - Physical impairment making moving the chair into your home and/or light assembly impossible
    • - You prefer having it all done for you hassle free and don’t mind the extra week or so in delivery time.

    With White Glove Delivery, our team will bring your chair into your home, place it exactly where you’d like it and assemble it.  Then, they will remove the debris making it a very easy, hassle-free process.

    Notes: 

    • - White Glove delivery does take a bit longer. Your chair will be ship LTL for the long haul of its journey and then change hands to the final mile white glove agent.  

    • - When you receive your tracking, it may show your chair as being delivered.  Don’t be worried!  This just means that your chair has been delivered to the final mile / white glove agent.  

    • - Once the white glove team has your chair, they will call you to schedule your delivery.
    • Pro Tip: you can call them once the chair is delivered to expedite / get ahead of the delivery process. They will not deliver your chair without a scheduled appointment.  

    • - White glove fees are non-refundable. If for some reason you decide not to keep your chair, you will be responsible for boxing your chair back up and/or paying for a white glove pick up which can be pretty expensive.  If you’re not sure about the chair, we recommend keeping the boxing material to make it an easier and less expensive process.

    Some of our massage chairs arrive fully assembled.  Most of our chairs require some light assembly.  All tools are included.  Assembly should be intuitive and take 20-30 min.  It is often helpful to have 2 people for the assembly as one can balance while the other makes the connections. 

    Assembly typically entails putting on the side panels and the footrest.  

    • - Side Panels:  connect the airhose and electric securely. Next you will need to attach the side panel onto the base of the chair–usually with a bolt system.

    • - Footrest:  securely connect the airhouse and electric; position and connect the male/female cotter pin attachment; zip up the enclosure

    • - Plug in your chair and enjoy. 

    Health & Safety

    Massage chairs have been known to dramatically improve people’s sleep, are fantastic for relieving stress, muscle tightness/tension and pain.  Here’s a short list of some of the health benefits:

    • - Relieve pain and loosen muscles in the back, neck and shoulders.  
    • - Improve blood circulation
    • - Boost lymphatic drainage
    • - Reduce stress, anxiety and cortisol levels
    • - Improve your sleep
    • - Shorten your recovery time after workouts
    • - Improve your posture over time

    Yes! Many chairs are beneficial for both conditions.

    • - Sciatica:  gentle stretching and glute massage from either an SL track or dual track chair can help to ease nerve pressure and pain.

    • - Neuropathy:  gentle kneading and compression will improve circulation and bloodflow to nourish damaged nerves and reduce numbness or tingling; airbag compression and foot rollers can provide a reflexology massage to stimulate sensory nerves; heat and gentle massage can ease the burning or aching sensations and overall reduced muscle tension.

    • - Arthritis:  heat and light compression can help to reduce joint stiffness, inflammation and improve your overall mobility.

    The short answer – yes! Let your body be the guide. If something feels too intense or hurts, back off on the intensity. It will be critical to make sure that you have a chair that allows you to easily adjust the intensity, duration and style of your massage.  You may find that during this time you prefer a gentler experience.  Most of our 3D and 4D chairs are very adjustable.  Also, the manual mode will be very beneficial so that you can directly control the position and intensity of the roller to get targeted relief.  Be sure to consult your doctor before using if you have medical concerns.

    Yes–with the right model.  Many of our chairs are senior-friendly with gentle programs and the ability to control the intensity, width and speed of the roller mechanisms.  Remotes have become far more intuitive with the better models that have touchscreen tablets, Ai to directly sense your body and adjust the intensity of the program to suit your immediate needs.  A robust manual mode will also help you to pinpoint exactly the right massage for your needs on any given day.  People with pacemakers, recent surgeries or spinal issues should consult their doctor before use.
