Comparing the Infinity IT-8500 & the Positive Posture Brio

8500 vs brio

The Infinity IT-8500 vs the Positive Posture Brio 

When investigating massage chairs, particularly fairly expensive chairs, some features can make or break your decision. When you look at the IT-8500 and the Brio, the style of massage they offer and the additional features included contrast greatly. Which of these $4,999 massage chairs will offer the massage you want? These chairs provide an S-Track or L-Track massage, and there are some supplementary features that differ as well.

Let’s start with understanding the most important feature- the massage track.


The S-Track, named after the S-shape of the human spine, is the standard track found in a massage chair. The S-Track rollers move up and down your back without losing contact with you as they follow the natural curvature of your spine.

It moves more forward at your neck and lower back and comes back a bit at the middle back and tailbone so that you receive the most comfortable, most effective massage. Spines aren’t straight lines, after all, so you don’t want the track to be a straight line.


l-track it-8500

As developments in massage chairs progress further, the S-Track was extended into the L-Track. The L-Track can travel down the spine under the seat to the glutes and hamstrings. The first L-Track prototype was an Inada.

However, Inada took time to perfect their chair, and because of this Infinity launched its Iyashi model, the first commercially available L-Track massage chair. More and more models have come out since then, and many have started to implement the extended L-Track for greater massage coverage.

S-Track vs. L-Track

When you’re examining each track, think of it this way. The L-Track is an extension of the S-Track that massages your seat and hamstrings. It can work the glutes, piriformis, and hamstrings just as effectively as the neck, mid-back, and lower back. Before the L-Track was created, these areas could only be reached by airbags.

If you suffer from tight or sore glutes or have sciatica or piriformis syndrome, an L-Track could be a great addition to your massage chair. And remember, an L-Track massage chair still delivers the benefits of an S-Track. After all, the L-Track is just an extension of the S-Track.

Now, let’s take a look at what these specific chairs offer.

Infinity IT-8500

it-8500 feature set

The Infinity IT-8500 massage chair is one of the best-selling Inversion therapy massage chairs offered by Infinite Therapeutics. Designed with several high-end features, this chair provides a quality massage experience using innovative technology like inversion therapy positions that relax parts of your body that the massage roller can’t reach. Learn more about this inversion therapy massage chair below.


Inversion Therapy

Inversion therapy is what Infinity massage chairs are best known for. By putting gravity to work for you, the IT-8500 lengthens your spine, allowing the vertebrae to decompress and relieving pressure throughout your back. This chair has numerous pain-relieving benefits for both your neck and your lower back.

Zero Gravity

The zero gravity position, introduced by NASA a few decades ago, is designed to mitigate stress on the body as the result of gravity. The Infinity IT-8500 offers two stages of zero gravity that raise your legs above your heart to promote better circulation and minimize gravity’s influence on your spine and joints.

Spinal Correction

Through the Tru-Grip V Stretch program, you can improve your posture each time you enjoy a massage. As the airbag system works with the back rollers, the chair grabs you and stretches out the muscles along your spine to relieve tension and promote proper alignment.

Waist Twist

The seat twists your hips from side to side to stretch the lower back and hip muscles. This loosens up tension in the lower back and hips that cause lower back pain. This feature has three levels of adjustable speed and is available at the push of a button. You can combine this with your massage or use it alone.

Optical Body Scanning

Every time you start a massage program, the rollers glide up your back to map of your unique shape and curvature. This ensures that the rollers hit all of the right muscles. This has become a staple in modern massage chairs so that every user can receive a customized massage.

Quad-Style Massage Roller

The IT-8500’s massage roller features four massage heads that mimic the feel of human hands. There are three levels of width adjustment as well as six adjustable speed levels. This style of massage roller is advanced and has become a staple in most modern chairs.

30” S-Track

The S-Track accurately mimics the curvature of the human spine for a uniform massage across your entire back, including often neglected areas such as the lower back and the upper shoulder areas. At 30” long this track makes the IT-8500 ideal for users from 5’1” to 6’4”.

Elaborate Airbag Massage System

There are 38 airbags strategically placed throughout the chair that offer a compression massage to your hands, arms, legs, shoulders, and feet. This system is the basis for almost all of the stretching programs in the IT-8500. The system works in tandem with the rollers and by inflating in the shoulder, lower back, and foot area, you’ll receive a deeper tissue massage.

Lumbar Heat

Heat therapy is a quick way to loosen up muscles. Two heating elements have been placed in the lumbar of the backrest to help loosen up the large muscle groups in the area. This home massage chair allows your back massage and stretch programs to be even more effective, and greatly improves the benefit you receive from your massage.

Foot Massage Rollers

Massage rollers built into the leg rest deliver a vigorous, relaxing reflexology massage that targets acupoints at the bottom of your feet. There are three massage rollers in each footrest that offer three levels of adjustable speed to suit your personal tastes.

Intuitive Panel-Style Remote

The remote provides easy access to everything you need to quickly personalize your massage. There are four automatic programs and six massage styles to choose from to customize your massage.

Six Massage Styles

The six massage styles present include Kneading– deep strokes that focus on stretching the muscle, Tapping– quick, light taps on both sides of your back to relax muscles, Dual– combines Kneading and Tapping, Knocking– alternating tapping on either side of your spine, Shiatsu– firm strokes that relieve tension, and Synchronic- syncs up with your paired music device to provide a rhythmic massage.

Four Massage Programs

The four massage programs include Recover– full body massage for post-workout recovery, Refresh– ideal for morning time wake up routines, designed to revitalize and refresh the body, Extend– focuses on deep tissue massage and stretching, Relax– a lighter massage routine for relaxation and is ideal right before sleep.

Manual Massage Adjustments

Personalize every part of your massage from the technique being used and the area being massaged to the speed and width of the rollers. The remote lets you quickly make manual adjustments to your massage so that you can customize your massage to your needs at any given time.

Spot Massage

This feature allows you to pinpoint the location of your massage to work out specific areas of tension.

MP3 Player & Built-in Sound System

The sound system is quite impressive with built-in speakers that point inward instead of out into the room. It’ll create your own little world of relaxation. Plus, you can use any USB stick with your MP3’s on it and listen to your favorite music.

Independent Backrest and Footrest Recline

The backrest and footrest can be raised and lowered independently so that you can find an ideal position for lounging or sitting while receiving your massage.

Accu-roll Shoulder Massage Technology

This technology creates a more impressive upper body massage by tailoring the massage to your particular size and shape.

Now let’s look at the Positive Posture Brio.

Positive Posture Brio

The Positive Posture Brio provides an escape to rejuvenation and relaxation. L-Track massage technology allows the Brio to provide a true full-body massage from your head down to your hamstrings. Ten expertly choreographed massage programs can be paired with hundreds of manual massage combinations for customized relief. Quiet your body, clear your mind, loosen your muscles…and do it all from the comfort of your own home.


Intelligent Soft 4D Massage Mechanism

The Intelligent Soft 4D massage is based on traditional Chinese massage techniques. The Brio adjusts the depth of massage constantly during each programmed session and the soft-to-the-touch rollers recreate the sensation of a human hand relaxing the muscles in your back, neck, hips, and glutes.

L-Track Massage

l-track brio

The L-track extends the surface area covered down past your lower back, through your glutes all the way to your upper thighs while mimicking your body’s shape for a full-body massage.

Zero Gravity

True Zero Gravity® position improves blood circulation and alleviates joint and spine pressure. As your legs are raised above your heart it removes pressure from your joints and spine. This allows them to decompress and relax which deepens the effect of your massage chair.


Soothing, effectual heat in the lower back and feet helps soothe tension and promotes a deeper massage experience. Heat is a perfect addition to your massage as it helps to relax the muscles, making them more responsive to the rollers and airbags.

Body Scan

The Brio body scan determines your shoulder position and customizes each massage to your unique body type. The body scan feature is crucial when you’re considering a massage chair because you want your new chair to work well for your specific body size and shape.

Air Massage

Airbags can reach areas of your body that the rollers just can't get to. The Brio delivers a compression massage through the airbags that covers your fingertips to your shoulders, hips, and down to your feet.


space saving brio

Typical massage chairs may need up to three feet behind the chair to recline without damaging the wall. Positive Posture has engineered space-saving that allows the chair to slide forward as it reclines so that it only needs 10 inches to fully recline. Space-saving makes this innovative massage chair a very versatile piece of furniture.

Foot Rollers

The footrest rollers create a reflexology-style massage with soothing, kneading pressure. Acupressure points are stimulated with the inflation of airbags for a deeper massage experience for your feet.

10 Auto Programs

Ten program modes are available- Quick, Full Body, Refresh, Relax, Meditate, Stretch, Neck & Shoulder, Low Back, Feet & Calves, and Full-Body Air Massage.

Stylish Remote Control

Easy to read and use, the remote combines style and functional simplicity. Choose your massage, then store your remote in the pocket at the side of the chair so that you can totally relax during your massage.

Deciding Factors

best for you

When deciding between these two chairs, the massage experience you’re looking for is the most crucial factor in your purchase. Both of these chairs offer similar massages, some of the same features, but their massage tracks differ. 

The IT-8500 offers an S-Track massage whereas the Brio offers an L-Track massage. Additionally, the Brio provides zero gravity as does the IT-8500, but the 8500 also offers inversion. The inversion feature can be very nice if you have lower back pain or lower extremity swelling. The L-Track feature can be preferable to this if you want the massage rollers to attend to your glutes and hamstrings, which can be great if you’re active or a runner.

Plus, the Brio provides a deep tissue, 4D massage where the 8500 is a 2D massage chair, and the Brio is a space-saving chair. The IT-8500, however, provides a Bluetooth system, waist twist, and Accu-Roll Shoulder Massage Technology. These features are quite different from each other. Do you want a chair with more individual features, including music, or are you looking for a chair with a stronger base massage?

What it all comes down to, as it does with most purchases, is your personal preference in a massage. What experience are you looking for and what chair delivers that experience for you?
