Teeter FitSpine X1 vs. Ironman Gravity 4000 – My Honest Review

Are you looking for a great inversion table?  In this article, I will compare the Teeter FitSpine X1 vs. Ironman Gravity 4000.  These two inversion tables share some similarities but have some pretty significant differences as well.  Sit tight, and we will dissect each of these popular inversion tables and see which one is right for you.

I have been dealing with back problems for about 20 years, and using an inversion table is one of my go-to methods for pain relief. I have used an inversion table to recover from injuries, and now I use one to maintain a healthy back.

There are a lot of different choices when it comes to inversion tables.  Today I want to take a look at two top-rated models, the Teeter FitSpine X1 inversion table vs. Ironman Gravity 4000.  I currently own a Teeter but have also used the Ironman Gravity inversion table.

I will take a look at different categories that I feel are important and tell you which inversion table has the advantage. So let’s take a look at these two top-rated inversion tables.

Teeter FitSpine X1 vs. Ironman Gravity 4000


Backrest

Teeter FitSpine X1

Teeter uses the FlexTech backrest on the X1, and this is an excellent feature.  The backrest is (as the name implies) designed to flex with your movements.  The 8-point floating suspension system flexes as you move.

I can tell you from experience that Teeter backrests are very comfortable, durable, and flexible. The FlexTech bed is also equipped with built-in handgrips for side to side stretching, acupressure nodes, and a lumbar bridge for your lower back. Teeter has put a lot into the design of the backrest and its top-notch.

Ironman Gravity 4000

The Ironman table uses a memory foam backrest that is comfortable to lie on and easy to clean.  Again, I have experience using this table, and the backrest is comfortable.  The backrest is not designed to bend or flex with your movements, and some argue will prevent decompression because you sink into the foam.

The backrest does not include acupressure nodes, but it does come with a lumbar pillow.

Advantage: Teeter FitSpine X1


Inversion angle adjustment

There are two different mechanisms or concepts when it comes to adjusting the inversion table angle.  I will discuss each option and tell you which I prefer and why.

First, there is a pushpin type system, where you have preset inversion angles.  The preset angles typically come in 15 or 20-degree increments, like 15, 30, 45, 60, or 20, 40, 60 degrees as the options.  These are great for most people, and they are foolproof, pick your angle, and rotate backward. These do have limitations, though, more on that in a minute.

The tether strap is the other option, where you can set any angle you want.  You adjust the strap length, and that establishes your inversion angle.

I mentioned limitations earlier when using a push pin inversion angle because you are limited to the preset angles, which is a problem for folks like me.

In late 2015, I suffered a pretty severe back injury and was dealing with spinal stenosis, which meant I was bent over about 30 degrees at the waist. I couldn’t stand up straight (or lay down flat on my back). The pain was unbearable.

As I progressed in my recovery and was able to lay flat, I began to use my inversion table.  Thankfully my table has a tether strap.  See, I had to start with a shallow angle like 15 degrees and slowly work my way to a steeper angle from there.

During my recovery, there was no way for me to make a 15 or 20-degree jump. I had to make much smaller adjustments.  That is why a preset, pushpin inversion angle adjustment would not have worked for me.

Again, this is something that might not be an issue for some people, but it’s worth noting.

Advantage: Tie, both use a tether strap


Ankle locking system

When you are hanging upside down, you want to feel secure, like you are not going to end up headfirst on the floor. The ankle locking system on an inversion table is critical.

I break the ankle system down into three components, locking/release handle, the ankle cushions, and the footbed.

Teeter FitSpine X1

This unit has a short locking/release handle, and that is one strike against this machine. Let me explain.  A shorter handle means you have to bend over farther to secure your ankles in the unit.  If you have back problems, as I have in the past, bending over is not ideal, or may not even be possible.

Teeter does make up for this with very comfortable ankle cushions. The cushions are contoured to fit securely around your lower leg, just above your ankles.  These ankle cushions are very comfortable.

Finally, we have the footbed, which is what you step onto when you get on the inversion table. Teeter is one of the few inversion tables that has an adjustable height footbed, which helps to customize your fit.

Ironman Gravity 4000

The Ironman model has a long handle, which is a plus in my book since it requires less bending over.

The ankle cushions are comfortable enough and are designed to cup the front and back of your leg for a comfortable and secure fit.

The footrest is not adjustable on the Ironman inversion table, but this may not be an issue for some people.

Advantage: Ironman Gravity 4000, the more extended handle wins out.


Weight capacity

Teeter FitSpine X1

The weight capacity of this unit is 300 pounds, which will work for a lot of users.

Ironman Gravity 4000

The Ironman unit is known for being a “high capacity” inversion table, with a weight limit of 350 pounds.

Advantage: Ironman Gravity 4000


Price

Teeter FitSpine X1

At around $330, this is the more expensive of the two models.  Teeter does offer a payment plan and a 30-day in-home trial.  With the FitSpine X1, you do get acupressure nodes included, the FlexTech backrest, and adjustable height footrest.

Ironman Gravity 4000

Coming in at around $200, this is the less expensive of the two models.  The Ironman version has fewer features, but if you are looking for a more bare-bones option that will get the job done, this might be your best bet.

Advantage: Ironman Gravity 4000, strictly based on price


Assembly

FitSpine X1

Teeter has made assembling an inversion table very efficient.  These inversion tables arrive about 85% already put together.  There is an app to help you finish the job so you can start using your inversion table right away.

Ironman 4000

The Ironman requires a bit more work to assemble, but it is not terribly difficult.  Plan on about an hour, maybe less.

No matter which table you choose, I recommend having someone help you build the table.  Inversion tables are cumbersome and awkwardly shaped. If you are dealing with a back problem, having someone to help assemble and set up is a great idea, speaking from experience here.

Verdict: Teeter FitSpine X1 vs. Ironman Gravity 4000

First off, I will say that you can’t go wrong with either one of these inversion tables.  If you are looking for a budget-friendly model, I think Ironman is a great option.  The Ironman Gravity also has the more extended locking/release handle, which is a must, in my opinion.

The FitSpine X1 does come with some features unique to Teeter, but I think, in this case, the Ironman offers substantial value.
