The Ironman Gravity 4000 Inversion Table is one of the latest from Ironman and is known for both its comfort and effectiveness.

Packed with comfort features to enhance your inversion experience and relax your muscles, it is an improvement on their earlier Gravity 1000 and Gravity 2000 models.

The inversion table is an important item of equipment used for inversion therapy by doctors and other health care professionals.

This particular table is quite possibly one of the most sturdy on the market today and is a must for those wanting, or needing, to carry out inversion therapy.

The Gravity 4000 is very easy and comfortable to use during inverting routines due to its high quality memory foam padding, providing comfortable support throughout the exercises. This frees the user to concentrate on the therapy session for maximum effectiveness.

The Ironman Gravity 4000 Inversion Table


Whether it’s just to relax or you want to use it for your back or neck therapy, the Ironman Gravity 4000 inversion table has been designed to make using it as comfortable as possible, which is  especially important the older we get.

Using the table requires the use of your hands and fingers as you rotate.   Because of this, the designers have made it a point to protect your hands and fingers by the provision of vinyl side covers.


The Gravity 4000 inversion table is very easy and straight forward to assemble as it comes with clear and easy-to-follow instructions.  You should therefore be able to have it up and running in no more than about 30 minutes.

Not only that, it’s also easy to use, can be used at any time and will adjust to your comfort requirements.

Build Quality

Engineered for endurance, this inversion table is well known for its extra wide, durable heavy-duty tubular steel frame with an anti-scratch finish giving additional stability, durability and security during the inversion process.

It also has a memory-foam vinyl covered backrest for comfort with extra comfort being provided by means of a removable lumbar pillow for lower back support.

Whether it’s just to relax or you want to use it for your back or neck therapy, the Gravity 4000 inversion table has been designed to make using it as comfortable as possible, which is especially important the older we get.


Ankle Support

At the same time, less bending is required to get the ankle clamp on. This is made easy by the Gravity 4000’s easy-to-reach Palm-Activated adjustable ratchet type locking system.

When you compare this method against some other inversion table models which use rollers, this is much more comfortable.


The table frame will work for people who are tall as the frame is height-adjustable up to a maximum of 6 feet 6 inches and comes with a safety lock that keeps the table securely in place.  The table also supports users of up to 350 pounds weight.


There are some inversion tables around where people have a hard time getting down and an even harder time getting up!  This is not the case with the Ironman Gravity 4000 Inversion table.

The device has three adjustments for different starting inversion angles.

At the completion of your inversion therapy session, it is a simple matter using the extra- long safety handles to rotate your body back to the upright or normal position without any undue strain.

Because the 4000 is very sturdy, at around 75 pounds, it is quite a heavy piece of equipment and care should be taken when moving it.


One of the major concerns when picking an inversion table is safety. The Ironman Gravity 4000 comes with durable rubber, non-skid, floor stabilizers. These enable the user to invert themselves confidently and without having to worry about whether the table will slip or not.

There are also extra-long U-shaped handrails for additional stability. This ensures that the Gravity 4000 provides maximum stability, does not move around and is completely safe in use.
