My Personal Experience Using Infinity IT-8500 Plus Massage Chair

Being knowledgeable about massage chairs, I have had ample opportunity to use the Infinity IT-8500 Plus Massage Chair. I must say, it is quite an impressive machine. One of the standout features that caught my attention is the 3D roller technology.

The roller track of the IT-8500 Plus massage chair is more advanced than traditional chairs as it can move in multiple directions, allowing you to focus on specific areas of your body. I found the deep-tissue massage to be vigorous but not uncomfortable.

I was impressed by the airbag compression massage feature in the chair. The chair has airbags distributed across the shoulders, arms, hips, and calves. This massage helps improve blood circulation, reduce muscle soreness, and I found it especially useful for my calves after my workout.

For those seeking relief from muscle tension or arthritis pain, the chair includes heat therapy as an excellent feature. The heated rollers work together with the airbag compression massage to provide a calming and relaxing experience.

I found the IT-8500 Plus chair’s customization options to be great. Although it already has six auto programs like Relax, Refresh, and Deep Tissue, you can still personalize your massage by modifying the intensity, speed, and roller width according to your preferences.

The chair has advanced TrueFit technology in its hardware and software that can measure the user’s size and shape, resulting in custom massages.

The IT-8500 Plus has a good zero-gravity feature that lifts your legs over your heart, easing the pressure on your spine and aiding relaxation. It’s worth noting that the massage function is quite loud, which is a minor drawback. Nonetheless, the benefits of the massage are more significant than the noise.

Compared to Other Chairs

The main competitor IT-8500 Plus has the highest price tag, while the Brio Plus is a bit cheaper, Osaki OS-Pro 3D Admiral is the most affordable massage chair in this mid-price segment of the market.

Positive Posture Brio+

See Price
The IT-8500 Plus massage chair is a superior model compared to the Positive Posture Brio+ Massage Chair. IT-8500 offers many more features, including an Inversion Feature, 8 motors instead of 2, Neck/Head Airbags, 38 airbags/aircells instead of 26 on the Brio+, and 45 minutes of max massage cycle time compared to the 30 minutes of the Brio+. Ultimately, the IT-8500 Plus provides a more comprehensive massage experience. Additionally, it offers greater customization and comfort for users, making it the better choice for those seeking an effective and relaxing massage chair. Overall, Infinity is the clear winner between these two models. It provides a more comprehensive range of features and functions than the Positive Posture Brio+, making it an ideal choice for those seeking a higher quality massage chair.

Osaki OS-Pro 3D Admiral

See Price
The IT-8500 Plus and the Osaki OS Admiral Pro massage chairs provide a range of features to suit different needs. The IT-8500 Plus is more feature-rich than the OS Admiral, providing 8 motors as opposed to 6, a music system, and neck/head airbags for added comfort. Additionally, the Infinity model has an in-version feature and waist airbags that are not available on the OS Admiral. Therefore, for those who are looking for a higher level of comfort and features, the IT-8500 Plus may be the better choice. However, if budget is a priority, then the Osaki OS Admiral Pro might be more suitable.

The final decision should be based on personal needs and preferences. Overall, all three massage chairs offer excellent massage capabilities that can provide a comfortable and relaxing experience.

Here is a table that compares some of the features of the Infinity IT-8500 Plus Massage Chair and the Positive Posture Brio+ Massage Chair:

What Makes Infinity IT-8500 Plus Massage Chair Stand Out from the Competition?

The Infinity IT-8500 Plus Massage Chair stands out from the competition with its advanced features and technology. It is designed to give users all the features they need for a deep-tissue therapeutic massage. Plus, the best-in-class spinal decompression feature provides a full body stretch second to none.

The chair has received some serious upgrades, including a color screen LCD remote, app functionality, and in-built nature sounds. Users can seamlessly play their favorite tunes through the chair’s Bluetooth®-enabled sound system. Plus, the Apple® and Android™ app allows you to easily control your massage from your device.

The IT-8500 Plus still includes feature favorites such as a body scan sensor system for a more accurate massage experience, an unprecedented spinal decompression stretch, soothing lumbar heat, and rejuvenating foot rollers.

The 4-Node back massage mechanism provides five different massage techniques as it travels down your back. It was designed to realign the spine with a Decompression Stretch, Waist Twist Therapy, and Near-Flat Reclining S-Track that reaches true inversion.

Infinity IT-8500 Plus Massage Chair Notable Benefits & Features

Quad Style Roller

Featuring a quad massage roller that has a 30″ track length, the Infinity IT-8500 Plus massage chair can massage your lower lumbar area and neck. Suitable for people of 5’1″ to 6’4″ in height, and with three width adjustments, it fits most body types. A Quad Style roller has four massage heads that mimic human hands.

With six adjustable speeds, the roller moves up and down your back according to the S shape curve of your spine.

Body Scan Technology

An extensive body scan feature comes standard with the Infinity IT-8500 Plus. By scanning your body with this technology, you can pinpoint the shape of your spine and where your curves are located. This type of technology helps massage chairs become more versatile and capable of massaging a wide range of body types and sizes.

Automatic Programs

You can choose from seven automatic programs with the Infinity IT-8500 plus massage chair: Sports Refresh, Extension, Rest & Sleep, Working Relief, Neck & Shoulder, Waist & Spine, and Demo.

Waist & Spine Program

Waist & Spine’s spinal correction feature uses powerful stretching techniques to extend and decompress your spine, reducing back pain. A milder option for back pain relief is waist twisting, which is included as an alternative on the IT-8500 Plus.

Decompression Stretch

Incorporating strong kneading and stretching movements, the Extension program decompresses the entire body.


From your neck to your lumbar region, Infinity’s S-track design suits the natural shape of your spine to hit all your areas of tension.

Lumbar Heat

As your body prepares for the massage, the heating modules at the back of the chair provide you with a soothing sensation and loosen your muscles.

Infinity IT-8500 Plus Modifications and Differences

Infinity IT-8500 X3 Massage Chair

  • Near Flat Reclining S-Track: From the neck to the lower back, the S-track rollers follow the spine’s curve, allowing you to get a full-body stretch – your hips are held in place and your legs are pulled down.
  • Spinal Correction and Decompression Stretch: As you recline the massage chair, its airbags grip your shoulders and legs to soothe and relieve your spine during this full-body stretch. To relieve back pain, the spinal correction feature uses powerful stretching techniques to extend your spine and decompress it.
  • Lumbar Heat: You will be able to relax your muscles and loosen your muscles before receiving a massage by using the heating modules in the lower back of the chair.
  • True Inversion: As you recline the chair below a horizontal level, your head will be inverted and your heels will be up. This technique relieves pressure on your spinal column by putting your head down and heels up.
  • Waist Twist Therapy: Tight muscles are stretched with a gentle twist of the hips in a compression massage.
  • Apple® & Android™ App Functionality: Its app-based functionality allows you to control the chair from your Apple or Android device.
  • Truefit™ Body Scanning: Using special technology within the chair’s hardware and software, the chair is able to measure the user’s size and shape, allowing for individualized massages.
  • 360° 4-Node Plus Massage: With its Enhanced 4-Node Plus Back Massage Mechanism, you will experience five comprehensive massage techniques over the length of your spine: kneading, tapping, kneading+tapping, shiatsu, and knocking.

Infinity IT-8500 Massage Chair

  • S-Track Design & Quad Rollers: There are some lower-end models of Infinity chairs that utilize tri-rollers rather than quads. These are marginally inferior and disadvantage Infinity’s less expensive chairs. There is a solution to that problem with the 8500 series, which combines S-Track with quad rollers, both of which are industry standard. This is a great start and gives the model a strong foundation.
  • 3D Body Scan: Two-pronged adjustment is available for the roller positions and the massage area width on the Infinity IT 8500 zero gravity massage chair. With the automated 3D body scan technology, your pressure points are located and adjusted automatically. As a backup, the 8500 comes with a remote control that lets you fine-tune the adjustments so that you’re always getting a world-class massage.
  • Zero-Gravity Seating: It’s always great to see zero-gravity seating implemented in a product like the IT 8500. The IT 8500 features two different positions that are all accessible with a single touch. Due to the positive impact it has on the overall massage experience, this feature is so popular. Your body’s weight is pressed down against the rollers as you recline to a position where your knees are elevated slightly above your heart. This results in a deeper, more penetrating massage.
  • Amazing Number of Options: Normally, Infinity excels at this aspect, but the base model didn’t quite live up to expectations (corrected in the X3).
  • Spot (“Part”) Massage Function: Infinity has implemented this feature quite well. In fact, users were impressed with how well it was implemented. There are two types of spot massage. Press the button once the rollers hit a sore spot, and they will remain within a six-inch radius of that spot until you release the button. A floating partial massage is also offered by the IT 8500 massage chair. Instead of selecting specific regions, as this feature is usually implemented, you can enter a partial mode while a massage program is running.

Infinity IT-8500 Plus Warranty

  • 5-Year Residential Limited Warranty.
  • 5 Year structural framework warranty.
  • 3-Year No-cost replacement on covered parts.
  • 1-Year Complete Care/No-cost parts & labor (in-home, if necessary).
  • Unlimited USA-based customer & technical support.

What Do Users Say About Infinity IT-8500 Plus Massage Chair?

There were a couple chairs at Brookstone I tried and I wasn’t very impressed with the deep massage roller. I was recommended this chair because of the deep massage roller. I have neck pains and I really like the program that uses the airbags in the pillow. I also like the stretch program for stretching my back. Thanks for the help, I use my chair all the time.”

“The foot massage and the way the chair squeezes my body makes me very relaxed. I admit I was skeptical of this chair because I saw some bad reviews. My experience has been excellent. I like the strength of the back massage and on days I’m not in the mood for something so strong I lay a small pillow over it. After having my chair for 6 months, I have noticed a lot of my body aches have reduced.”

Frequently Asked Questions

Where are Infinity Chairs Made?

China. Their massage chairs are manufactured in China, but most of the assembly takes place in the United States for quality control. They also custom-build every model to meet the specific needs of our customers.

Does IT-8500 Plus have a Consistent Spine Massage?

It retains tension in the spinal column, resulting in stiffness and fatigue due to a vast bundle of nerves. Using the IT-8500 Plus, long, continuous massage strokes are delivered from the cervical spine to the lower lumbar region through pressurized massage strokes. Allow the high-tech rollers to knead out tension, improve blood circulation, and even improve digestion as you sit in your massage chair.

Final Thoughts

With the new color screen LCD remote, app functionality and nature sounds, the Infinity IT-8500 Plus Massage Chair offers a unique experience. You can seamlessly play your favorite tunes through the Bluetooth sound system and even use the Apple or Android app to easily control your massage. 

It’s important to know that you’re investing in comfort and longevity when you buy a massage chair. Infinity even tested the IT-8500 Plus in a potent dose of sodium hydroxide for 72 hours to ensure unparalleled corrosion resistance and wear resistance. A very breathable material is used to maintain your chair, which is easy to clean and protected against extreme temperatures.
