Ironman Gravity 3000 Inversion Table Review

Also known as the Ironman 5800, the Ironman Gravity 3000 Inversion Table features a number of upgrades over the earlier 2000 model.

This includes switching the standard back support foam for multi-layered memory foam for increased comfort, and using Ironman’s patented ratchet locking system for easy release of the rubber heel holders.

In this review we’re going to take a closer look at the design features, as well as making some important comparisons with other models in the Gravity collection to determine which is the best value for money.

Design features

The Gravity 3000 allows for a full 180 degree inversion range

Although inversion tables don’t tend to require particularly long sessions (2-5 minutes being recommended by Ironman, twice per day), it’s still important to feel comfortable.

That’s why as we move up from the Gravity 2000 model, one of the improvements has been to use memory foam for the back support cushion. This has been enclosed in a water resistant vinyl cover and sealed with double stitching to increase durability.

The 2.5″ thick memory foam does an excellent job of keeping your back aligned and receiving as much support as possible, despite the lack of a lumbar pillow (available on the Gravity 4000).

Also, if you’re new to inversion therapy, you might not want to take advantage of the full 180 degree range of motion right away. This is why Ironman have fitted an adjustable tether strap to the underside of the back support. This joins to the front of the double U-frame and limits the inversion angle to something you’re more comfortable with.

This is also helped by the pivot arms, which offer three different angles for creating a greater or lesser degree of inversion.

If you do decide to go straight for the full 180 degree motion, the extra long, foam-covered safety handles make it much easier to pull yourself back around to an upright position.

Strength and stability
The frame itself provides a higher weight capacity (350 lbs) than lower priced Ironman models, which is also an improvement over popular inversion tables from Teeter Hang Ups, such as the Teeter EP-560.

This is helped by the extra-wide tubular steel frame, which has been coated in a scratch-resistant powder-coated finish for improved durability and aesthetic appeal.

To improve safety and stability, the Ironman Gravity 2000 has also been fitted with safety vinyl side covers over the pivot point, and tough non-skid rubber floor stabilizers.

The final and perhaps most important feature we wanted to mention was the ratchet system. This is the handle that points upwards out of the rubber heel holders.

In earlier models (Gravity 1000 and Gravity 2000), this handle was much lower down, increasing the amount you had to bend to release your ankles from the holders.

By extending the length of the handle and switching from a spring loaded to a ratchet system, this reduces any strain that’s placed on your lower back.

Comparing the Ironman Gravity inversion trainers

Despite there being such a minimal difference in price between the Gravity inversion tables, we felt it was important to make some comparisons between key features to see which model represents the best value for money.

  • Weight capacity and product weight

    Despite the frame weighing around 40 lbs less than inversion tables in the higher priced ATIS collection, the Gravity 3000 actually has a higher weight capacity.

    The ATIS 1000, 3500, and 4000 each provide support for up to 325 lbs, while the Gravity 3000 is the lowest priced model in the Gravity range to offer the full 350 lbs.

    It’s also the earliest Gravity inversion table to include Ironman’s patented ratchet system for releasing the cushioned ankle holders.

  • Back support and comfort

    The back support has a maximum height adjustment to 6’6″, which is a standard that seems to be maintained across Ironman’s entire inversion table range.

    Although you’re missing the removable lumbar pillow that’s included with the Gravity 4000 model, you do still benefit from the added support created by the memory foam cushioning.

  • Warranty coverage

    The reason we wanted to compare warranty coverage is because we’ve seen it differ between models in the same collection for some types of fitness equipment.

    That’s not the case here, where the same coverage of one year on frame and 90 days on parts is available across all the Ironman Gravity inversion tables.

Ease of assembly and storage options

Assembly instructions for the Gravity 3000 include clear steps to follow and detailed parts drawings

To help cut down on the assembly time, Ironman have pre-assembled the frame and boom as much as possible, with the double U-Frame included as a single piece.

However, you’re still going to want to allow at least 60 minutes to be sure of getting the table setup in a single session.

The instructions themselves are broken down into easy to follow steps, with clear parts references and diagrams to help convey how each part should fit together.

The diagrams are particularly useful for instances where the textual instructions aren’t all that clear, such as when you’re attaching the nylon strap to the strap lock.

Although a lot of these stages are fairly self explanatory, it’s still useful to be able to follow along to make sure nothing is missed.

Reading through the user manual as you’re setting up will also help you decide which setting you use for the pivot arms. There are three available, each offering a greater or lesser degree of inversion.

Can it be folded flat?

The two main frame sections need to be separated if you want the table to fold flat

Due to the size of their footprint, this is one of the most common questions that gets asked of inversion trainers.

The short answer is yes, that the Ironman Gravity 3000 can be folded virtually flat (with the exception of the pivot arms). But it’s worth bearing in mind the effort involved.

As we mentioned in our earlier review of the Gravity 2000 model, the adjustable boom and back support need to be removed from the frame to fold down completely.

This means removing the protective covers from the tops of the folding arms, removing the handlebars if you have them attached, and lifting the adjustable boom and back support clear of the double U-Frame supports.

You’ll also need to detach the nylon strap that joins the two sections together.

When you consider the number of steps involved, and that the time it takes for disassembly and assembly may be greater than your inversion therapy session, is it really worth the effort?

Having the inversion table setup and ready to go means that a five minute session really does take five minutes, which is really the best option if you’re short on time in the mornings or evenings.

That’s why we would highly recommend finding a space where the Gravity 3000 can remain setup, particularly if you plan on making inversion therapy a part of your daily fitness routine.

There is an option to fold the double U-frame together and leave the boom and nylon safety strap attached. However, this means leaving the boom at an awkward angle with the ankle cushioners extending from the front, and it won’t be free-standing.

Although this particular model features a footprint of 49″ (L) x 26″ (W), this is no larger than the earlier 1000 and 2000 models, and actually considerably smaller than inversion tables in Ironman’s ATIS collection.

Ironman Inversion Table Buyer's Guide

Review Overview

Overall Review Rating

4.5 / 5

You might be surprised to see that the Ironman 2000 actually has a higher list price than the 3000 model on many ecommerce sites. However, when you add on the discounts the Gravity 3000 model usually costs around $20 more.

So is it worth the price difference?

In our opinion, yes. The memory foam alone makes for more comfortable inversion sessions, but you also have to consider the handles at the base for upper body stretching and the easy-release ratchet system for the heel holders.

Warranty coverage is the same whichever model you choose, as are the height settings, so you're not missing out there. The 50 lb added to the weight capacity may also be a deciding factor.

Although the list price for the Gravity 4000 is over $100 more than the 3000 model, it's often on sale for almost the same price, so it's worth checking both models on Amazon before making a final decision.
