8-Point Floating Suspension Bed by FlexTech

The 8-point suspension provides the efficiency of static beds seen on other brands and the flexibility to move and bend them. The FlexTech shifts with you as you pivot and stretch, providing additional support. You’ll find that the bed doesn’t tilt too much or too little but rather adjusts to your movements. Teeter products, including the X3, are FDA-approved for relieving pain and compression caused by various spine and neck conditions. The Teeter X3 is FDA-approved for back pain, sciatica, spinal degenerative joint disease, spinal curvature caused by tight muscles, degenerative disc disease, and spinal stenosis. You may also use it to treat herniated discs, facet syndrome, and muscle spasms in the neck and back. Inverted therapy relieves the usual spinal compression caused by gravity, allowing the spine to be gently stretched and elongated to alleviate pain and immobility.

Deluxe EZ-Reach Ankle System

Due to back or hip issues that cause you to have a hard time bending over, you may have been discouraged to use other inversion tables since they require you to bend down to lock in your ankles and feet.  The Deluxe EZ-Reach Ankle System includes a lever that helps you secure ankle support without bending. This fantastic feature allows you to bypass the initial pain and discomfort and move right into pain relief. 

EZ-Stretch Traction Handles

The EZ-Stretch Traction Handles are designed for beginners, but they’re helpful regardless of your experience level. With these handles, you can control the amount of spinal decompression and stretch you get, regardless of the angle. So, if you don’t like the feeling of being at a 60-degree decline but like how your back feels, you can use these handles to achieve similar results at 20 degrees.

EZ-Angle Tether

The EZ-Angle Tether is a clever idea. This angle tether is used to restrict how much the inversion table can tilt, and the EZ-Angle Tether comes pre-marked with precise angles. As a result, you can quickly set the angle to 20, 40, or 60 degrees without having to measure or guess. You even have the option to remove it entirely and hang it upside down. In any case, this is an excellent choice for those who need a quick and accurate angle adjustment.

Stretch Max Handles

You can count on the Stretch Max handles to assist you in your stretches. They’re used to aid you in positioning your body to achieve a deeper stretch than you could without any assistance. This function comes in handy for relieving muscle tension and back spasms. Part of what sets the entire FitSpin line of inversion tables apart from their competitors is that they’ve undergone extensive UL testing, even though it isn’t required for inversion tables. That in itself makes us trust Teeter even more.


The following is an in-depth review of the Teeter Fitspine X3 Back Stretcher Machine, including its advantages and flaws. 


The Teeter FitSpine X3 features a sophisticated and trendy build. In terms of design, this back stretcher machine almost seems futuristic that when you leave it sitting out, it will certainly catch someone’s eye. Non-use dimensions are 58” x 29” x 61” and weighs approximately 66 pounds.  The large size and heavy construction of this Teeter Hang-Ups product can make it difficult to move and store once installed, but it feels very sturdy and provides a great sense of safety and security once you use it.


The FitSpine X3 inversion table doesn’t have many of the assembly issues that other inversion tables do. It will arrive at your doorstep already 85% pre-assembled. All that’s left for you to do is click some of the primary components together and then attach the handles. This back stretcher machine also comes with an instructional DVD and an assembly app to make the installation as quick and easy as possible. There are also instructions for additional models, which can be a little confusing at first.

Build Quality

Once you see the Teeter Fitspine X3, it’s already apparent that quality was a significant focus at the design stage of this inversion table. Not to mention the certification it received from Underwriters Laboratories (UL) for outstanding quality and safety.  In most regions, heavy-gauge steel components are used to improve durability and longevity. The use of steel throughout may add some weight to the table, but it’s well worth having a product that can withstand time and continuous use.

Ankle Support

With ergo-embrace straps, you’re sure to get ample support for your ankles. These straps ergonomically encircle those ankles to help distribute weight more effectively, thus improving comfort and safety.   There is also an adjustable platform near the feet that can be modified to fit your specific foot size. This feature further increases ankle support and comfort.


The X3 model of the Fitspine perfectly suits users between 4′ 8” and 6′ 6” in height and weighs a  maximum of 300 pounds. That capacity is sufficient enough to cover a wide range of people.  However, those who are particularly short or tall will have to invest in another model.


With the X3 model, inverting is now more convenient and beneficial compared with most other types of tables. Thanks to the decompression surface that it utilizes, you’re now able to perform a greater number of body slides during inversion. Much-improved stretching is also made possible through the grip and stretch handholds.  The bed itself has an 8-point suspension system that can flex with the body while inverting. Finally, the X3’s state-of-the-art suspension system improves decompression rates while reducing back pain. 


This Teeter FitSpine X3 model is designed for convenient storage through simple folding when not in use. Its broad dimensions and weight make it difficult to store properly and are particularly bothersome for the elderly, who may find it challenging to move 70lbs of steel into their closet.  However, minus the mobility and storage concerns of the X3, you’ll be able to fold it with relative ease.  


Teeter has nearly four decades of experience manufacturing inversion tables and related products. This experience has provided the company with a thorough understanding of the requisite safety features, including cam locks, specially-designed bearings, and auto-locking hinges.  All of these features guarantee that the back stretcher machine you’re getting will function properly without endangering any of its users. A UL safety certification and stamp of approval from the FDA provide sufficient validation for these claims. 

Additional Features of the Teeter FitSpine X3 Back Stretcher Machine

Apart from its numerous safety and design features, the Teeter FitSpine X3 also comes with acupressure nodes, an EZ-angle tether, and traction handles, making it a truly feature-rich product. The acupressure nodes provide a much-needed pressure point relief at specific areas along the back.  You may also download a supported mobile app that allows you to monitor sessions, chart statistics, listen to tips, and contact customer support.


The FitSpine product comes with the option of a “free double warranty” for ten years. However, this warranty offer is only available if you purchase the product in full rather than the trial and payment installation program. Otherwise, you still get to enjoy a standard 5-year warranty and the option of returning the product within 30 days of purchase.

510(K) Medical Device

The Teeter X3 is the only inversion table on the market that is FDA-approved as a 501(k) medical device for muscle strain, back pain, muscle spasms, sciatica, and various other conditions. It can offer relief for these conditions in as fast as 30 days.


The Teeter FitSpine X3 isn’t exactly within the range of affordable, but it’s certainly worth the price tag. You can take advantage of two purchase options available: full payment or an easy monthly payment plan over 3, 6, or 12 months.


If a medical professional recommended the use of an inversion table to relieve your back pain or muscle spasms apart from your usual stretching routine, you’d be hardpressed to find a better model than the Teeter FitSpine X3 inversion table. Quite simply, it’s one of the best inversion tables out on the market today. Although it has its own set of flaws, like every other back stretcher machine, the Teeter FitSpine X3 is also the only inversion table on the market that is FDA-registered as a medical device.  If you want to test the product without any risks involved, you always have the option to do so within its 30-day trial period.  However, before testing healthcare products, make it a point to consult with a physician or your primary healthcare provider for appropriate advice and supervision.
