The Ironman Gravity 4000 inversion table was released in 2009, and isn’t currently in production – though it is still available on Amazon. Despite this, it is still an innovative, useful inversion table today.

Sturdiness over Portability

The Ironman Gravity 4000 is no different to tables from other top brands in that it is very strong. It boasts an extra wide frame, capable of holding a body weight of up to 350 pounds, and is long enough to accommodate users who are up to 6ft 6″. This is larger than most tables, including Teeter hang ups who’s tables can only hold a maximum user weight of 300 pounds. As a result of such sturdiness, the Gravity 4000 is quite heavy – about 75 to 80 pounds – and so it’s not the most portable inversion table (particularly if you have back problems already). The table can be folded away, but as it’s so big, folding it up doesn’t save a whole lot of space anyway. You can see from the advert below (at 2:21) the size of it when it’s folded.

This does make for a very durable model, so if you’re willing to leave it out and you have the space for it, there shouldn’t be a problem. It has a tough, powder coated finish, which makes it a lot less likely to be scratched and damaged than cheaper brands. Some of the higher priced models, such as the Teeter Hang Ups EP-550 come with a chrome plated finish, which in my opinion is stronger and more aesthetically pleasing.

Other Features

Your feet will be locked in by what Ironman call their “ratchet gear system” which includes their patented “push release”. This refers to the metal bar that reaches up from your feet. Upon pushing the top of this, your ankles will be released. You do have to bend a little to reach it, but it’s definitely better than having to lean all the way down and release your ankles manually.

Other conveniences include an optional lumbar pillow (which actually works for many users, unlike Teeter’s acupressure nodes), foam covered long safety handles, that enable you to lower yourself more comfortably, and non-skid floor stabilizers – a feature to be expected in any decent inversion table.


Takes about 30 minutes, and isn’t particularly difficult. Most of the bigger branded tables come with pretty clear instructions. Should you run into any problems, the customer service is probably a bit better than Teeter’s.


For the price, this table does a very solid job. You won’t be disappointed, but it does lack the special something of more up to date models. Similarly, there is no warranty offered on the Gravity 4000. This shouldn’t be a problem, as it’s such a sturdy model, but I would always advise purchasing a model with a warranty when buying a product of such size, designed for heavy use. If you’re on a budget, this is a great model, as you do pay dearly for some higher branded features that aren’t totally necessary.
