If you have a large frame or are tall, Ironman 4000 inversion table is the best choice. It has a 350 pounds weight limit, higher than most models, and provides support for heights from 4’10” to 6’6″.
The ironman gravity 4000 is quite easy to use. Most of the customer reviews found its ankle locking system extra long safety handles very helpful to adjust the tension without bending over
The height is easy to adjust. However, additional stability and weight capacity make this inversion therapy table quite bulky and heavy-duty. It measures 26 x 65 x 49 inches when set up, and the folded dimensions are 26 x 17 x 80 inches.
Though it’s foldable for storage, it remains quite bulky, and its weight of 75 pounds can be hard to handle. This bulkiness is unavoidable in such a sturdy table. Still, you need to decide if you’re ready to sacrifice storability for stability.

Ironman Gravity 4000 Inversion Table Review of Key Features
The Ironman Gravity 4000 features an extra-wide, robust tubular steel frame and one of the market’s sturdiest. The steel frame has a powder coated finish, which increases the resistance to abrasions, rust, and scratches.
The 2.5-inch memory foam vinyl covered backrest is sturdy and comfortable. Plus, it has vinyl side covers for a comfortable inversion. Overall, you’ll feel secure and supported when doing your inversion therapy session or trying to relieve your back pain.
There are three starting inversion angles, and this inversion table can also go to a maximum angle of inversion. Inversion is smooth and operates on your body weight. To invert, you only need to lie on the table, put your feet into the ankle supports, and raise your arms to hang upside down at a right angle.
The ankle lock system is palm activated, and you don’t have to bend as much as you would with the spring-loaded design of previous models. Your position is secured with an easily adjustable safety tether strap.
When you are done inverting, you need to use the extra long safety handles to pull yourself in the initial position.
The removable lumbar pillow provides increased lower back support. Ankle cushions are ergonomically molded and reduce your ankles and joints’ pressure.
The price tag of Ironman Gravity 4000 is well justified for such a premium, feature-packed inversion table. Finally, a 1-year warranty ensures a worry-free purchase.
