As of 2015, Teeter and Ironman Gravity manufacture the best inversion tables, according to BestInversionTables.org. Important rating factors include each table's weight capacity, warranty, price range and ability to fold for easy storage.
The Teeter product consistently outperforms competitors in almost all categories. Teeter models are on average slightly more expensive, but provide a variety of features in a more compact, easy-to-use package. Ninety percent of the Teeter EP-560 is shipped pre-assembled, and it offers auto-lock hinges, pressure-reducing ankle foam and the ComforTrak bed. This inversion table also comes new with a five-year comprehensive warranty. It is the highest-rated model Teeter offers due to its range of features and reasonable price point.
The comparable Ironman Gravity product weighs 15 pounds more than the Teeter product and is less user-friendly. While it costs less than the Teeter model, the Ironman Gravity 4000 is bulkier and more difficult to assemble. The IG 4000 handles a load of 350 pounds, which is 50 more than the Teeter, but the warranty on the Ironman spans only one year.
Lesser models of note are the Health Mark Pro Max and Body Power, which offer similar products, but with fewer features and much higher prices. While the Health Mark Pro Max can handle a load capacity of 600 pounds, it also weighs nearly 100 pounds, making it very inconvenient and dangerous to move around.
