Teeter Inversion Table Reviews: Comparing the FitSpine X1, X3, LX9 and EP-560

The Current Teeter Lineup: X1 vs X3 vs LX9 vs EP-560

Teeter’s own product sitemap lists four inversion tables for sale today: FitSpine X1, FitSpine X3, FitSpine LX9 and the EP-560 (Teeter). The FitSpine X2, which many older lists still feature, is no longer in it. So any review that ranks the X2 alongside current models is describing a table Teeter no longer sells.

The three FitSpine models share a frame family and a weight rating. Here is how their published specs compare side by side.

The table makes one point clearly. Capacity, height range, warranty and FDA status are identical across the three.

FitSpine X1: The Entry FitSpine

The X1 is the starting point of the FitSpine series. It has the FlexTech backrest on an 8-point Floating Suspension, Ergo-Embrace ankle supports with a spring-loaded closure and T-shaped grip, and an angle tether you adjust by feel rather than by printed marks (Teeter). It still offers full inversion with a secure lockout, like the rest of the range.

What it gives up is precision. Without degree markings, you find your angle by adjusting the tether and trying it. That works fine for someone who already knows how far they like to go. It is less comfortable for a first-time user who wants to start at a known, shallow angle and stay there. Our Teeter FitSpine X1 review goes through its specs and setup in full.

FitSpine X3: Marked Angles and an Easier Ankle Lock

The X3 adds two things over the X1. The first is the EZ-Angle tether, marked at 20°, 40° and 60°, so you can see and set your limit before you lie back (Innova’s ITX9600 sets a limit with a pin whose degrees are in its manual). The second is the Deluxe EZ-Reach ankle lock, with an extra-long handle and a micro-adjusting closure, which means less bending and less fiddling to secure your feet.

Long ankle-lock handle, 5-year warrantyMaker source

by TEETER

Best for beginners who want a visible, marked 20 degree limit.

Skip it if bending down to your ankles or balancing while you mount is genuinely difficult: the LX9 adds a raised boarding platform for that.

What the premium over a cheaper table buys is the longer ankle-lock handle, the 5-year warranty against Innova's 1 year, and a tether marked at 20°, 40° and 60°. The Innova ITX9600 also lets you set a limit with a pin whose degrees are listed in its manual, so a marked angle is not exclusive to Teeter.

These are product settings, not a recommended progression. Follow the current manual and any restrictions given by your clinician.

For most people buying a Teeter because of back pain, those two changes are the whole case for the X3. A beginner whose clinician or manual calls for the lowest angle can see that limit marked on the tether. Our Teeter FitSpine X3 review covers its dimensions, setup and safe use in full.

FitSpine LX9: The X3 Plus a Boarding Platform

The LX9 keeps the X3’s angle system and ankle lock and adds an arched frame and a raised boarding platform. Both are about the moment of getting on and off: you step up into the ankle lock instead of reaching down to it. If you have trouble bending, balancing on one foot, or reaching your ankles, that is a real difference. If you don’t, you are paying for convenience you won’t use.

Raised boarding platformMaker source

by TEETER

Best for people who have trouble bending, balancing on one foot or reaching their ankles.

Skip it if getting on and off is easy for you: you would be paying for convenience you won't use.

Same angle system as the X3, plus a boarding platform with an arched frame. Worth the step up only if getting on and off the table is the hard part for you.

We cover the LX9 on its own, feature by feature, in our full Teeter LX9 breakdown. Here it is enough to know what it adds to the X3, and that it adds nothing to capacity, warranty or angle control.

EP-560: The ComforTrak Classic, With Optional Heat and Vibration

The EP-560 belongs to Teeter’s older ComforTrak series rather than FitSpine. Its bed is the ComforTrak backrest, and its ankle system is the Ergo-Embrace support with a T-pin closure, the same style as the X1. Teeter lists it as UL Safety Certified at a 300 lb weight rating, with a five-year warranty (Teeter). If you own or are looking at an older ComforTrak model, our page on the Teeter EP-960 covers what its manual says and what to check on a used one.

It is also the only current Teeter table sold with heat built into the package. Teeter offers the EP-560 in a configuration with a Heat and Vibration Comfort Cushion, which it describes as having six vibration motors and radiating heat, and sells the cushion on its own as an accessory (Teeter). The FitSpine models do not come with heat or vibration as standard.

The EP-560 is still for sale on teeter.com. It is not discontinued, and the heated version is also sold as the EP-560V, the EP-560 with the cushion in the box. One detail before you buy it for the heat: Teeter’s own page for the cushion lists a one-year warranty, separate from the table’s five years (Teeter). The table, the cushion and the folded size are on our Teeter EP-560 inversion table page.

Is Teeter FDA-Registered? What the FDA Record Actually Shows

This is where Teeter really does separate itself from most of the market, and where most Teeter inversion table reviews get vague. Here is the record itself.

What K162702 Covers

The FDA cleared Teeter’s manual inversion table through its 510(k) process under number K162702. The application came from STL International, the company behind Teeter, was received on September 28, 2016, and was decided on December 30, 2016 as “Substantially Equivalent.” The device type is “Apparatus, Traction, Non-Powered,” product code HST, regulation 21 CFR 888.5850 (FDA, 2016). The same clearance also names Teeter Gravity Boots and three Teeter decompression devices.

Note the wording. The record names the “Teeter Manual Inversion Table,” not the X1, X3, LX9 or EP-560 individually. So the accurate statement is that Teeter’s inversion tables are 510(k)-cleared under K162702. Any claim that a specific model “was cleared in 2016” goes further than the record does.

What a 510(k) Is, and What It Isn’t

A 510(k) clearance means the FDA accepted that a device is substantially equivalent to one already legally on the market. It is not a clinical trial, and it is not proof that the device relieves back pain. It says the product belongs to a known device type and meets the requirements for that type.

The FDA classifies non-powered traction apparatus, the HST code that covers inversion tables, as Class I, its lowest-risk class (FDA).

“FDA-Registered Class I” or “510(k)”? Both Are True

Teeter’s own copy uses both phrases. Its company story says its tables are “UL Safety-Certified and FDA-Registered as Class I medical devices” (Teeter), while its product pages call them a 510(k) medical device.

Some readers take that as a contradiction. It isn’t. The device type is Class I, and this particular product was cleared through the 510(k) route. The FDA record supports both statements at once.

Two claims we leave with Teeter. The UL certification is the company’s statement; we have not checked it in UL’s own database. And the product pages say the tables are indicated for “10 back pain conditions”; that is Teeter’s framing, and we don’t repeat it as a finding.

Why Most Other Tables Have No FDA Record

The FDA only regulates inversion tables whose makers claim a medical use, and most makers don’t, so most tables sit outside FDA regulation entirely (Kassay, 2023). The same paper notes that the FDA’s device reporting database lists serious injuries from inversion table therapy, including spinal cord injury, fractures, lacerations and death, without giving a count or a rate. A 510(k) doesn’t make a table safe for everyone. It does mean Teeter chose to make a medical claim and went through the FDA to do it, which most competitors have not.

What Clearance Doesn’t Tell You About Results

Clearance is about the device, not the outcome. On results, the broadest evidence is a Cochrane review of 32 traction trials, which found that traction of all kinds makes little or no difference to pain, function or return to work in low-back pain (Wegner, 2013). That covers traction in general, not Teeter or inversion specifically. The more encouraging data are narrower, and we go through them in our page on what inversion is actually shown to do.

Where Teeter Isn’t the Right Choice

Teeter is not the answer for everyone, and the comparison above makes it easy to see who it doesn’t fit.

If You Want Heat and Massage Built In

The FitSpine models have no heat or massage as standard. Teeter’s only heated option is the EP-560 with its cushion, the EP-560V, which is our heat pick in our guide to the best inversion tables. If you want heat built into the table for less, Innova builds it into three tables at lower price points, each with a different pad.

The trade is visible in the last two rows: a one-year warranty and no FDA clearance declared. Our Innova buying guide goes through which of the three suits which kind of pain.

If You Weigh More Than 300 lb

Every Teeter table is rated to 300 lb. That used to be the ceiling across the mainstream brands, but it no longer is. Innova publishes a 350 lb capacity for its ITX1200, with a three-position pin and a 4’10” to 6’6” height range (Innova). If you are over 300 lb, no Teeter table is rated for you, and you should not go past a published limit. The one Teeter product rated higher is the DEX II, at 350 lb, and it is not a table: it holds you at the hips rather than the ankles, as our Teeter DEX II review explains.

If the Budget Comes First

The FitSpine models with marked angles sit in the premium tier. If price is the deciding factor, our full inversion table comparison covers the cheaper frames that still pass our filters, along with what each one gives up.

If You Have a Condition on Teeter’s Own List

Teeter’s contraindication list, which the company says also appears in the owner’s manual, tells users not to invert until a physician approves if they have high blood pressure, heart or circulatory conditions, glaucoma, a history of retinal detachment, osteoporosis, hernias, severe acid reflux, pregnancy or recent surgery, among others (Teeter). No model upgrade changes that. Our page on who should not use an inversion table sorts that list into what has been measured and what is caution.

The Verdict From Our Teeter Inversion Table Reviews: Which Model to Buy

Put simply, pick the cheapest Teeter that solves your specific problem, and don’t pay for features you won’t use.

For Most Back Pain Buyers: the X3

If you are new to inversion and want to start shallow and stay there, the X3’s marked angles are the feature that matters. It has everything the LX9 has for angle control and ankle security.

If Getting On and Off Is the Hard Part: the LX9

Choose the LX9 over the X3 only if bending down to your ankles or balancing while you mount is genuinely difficult. The boarding platform is the reason to pay more, and it is the only one.

If You Already Know Your Angle: the X1 or the EP-560

The X1 gives you the FitSpine bed and the same warranty and clearance without the marked strap. The EP-560 is the choice if you specifically want Teeter’s heat and vibration cushion, sold with it as the EP-560V.

Whichever model you choose, the limits are the same across the whole range: 300 lb, a physician’s approval if you are on Teeter’s list, and short sessions to start.
