Inversion tables let you hang at an angle, partly or fully upside down, to stretch your back and decompress after a long day of sitting or standing. Teeter is one of the best-known brands, and two of its models come up often when people shop: the FitSpine X3 inversion table and the DEX II decompression and core training bench. This guide compares the two, explains what to check before buying and covers important safety points.

Talk to your doctor first
Inversion is not suitable for everyone. Conditions such as high blood pressure, heart or circulation problems, glaucoma or other eye conditions, pregnancy, recent injuries and certain bone or joint problems are commonly listed as reasons to avoid it. Ask your doctor whether inversion is appropriate for you before you buy or use one. Our general guide to choosing an inversion table covers the basics in more depth.
What to look for in an inversion table
- Weight and height capacity: check the maximum user weight and height range in the listing, and make sure you fall well within them.
- Ankle locking system: you should be able to secure your ankles easily and firmly while seated.
- Adjustable angle and safety features: look for a way to limit how far you rotate so you can start with a slight tilt.
- Frame and stability: a sturdy frame, wide base and non-slip feet matter.
- Comfort: padded backrests, handles and a smooth pivot make a difference.
- Certifications: check what safety and regulatory claims the listing makes, and verify them from the manufacturer if they matter to you.
- Storage: check folded dimensions against the space you have.
Teeter FitSpine X3 Inversion Table
The listing describes the FitSpine X3 as an inversion table that comes with accessories and a deluxe easy-reach ankle lock. It lists a 300 lb capacity, states that it is FDA registered and UL safety certified, and says it was designed and patented in the USA. The easy-reach ankle lock is meant to make it simpler to secure your ankles, which is useful if you are using the table on your own.
